How Are Almonds Grown And Harvested? You Haven't Seen So Many Fresh Almonds Yet!Almond production -
These orchards primarily maintain bare orchard floors with synthetic herbicides in , , ha of almond orchards were sprayed with glyphosate; California Department of Pesticide Regulation, , leaving exposed soil for most of the year.
Glyphosate and other pesticides also have significant human health impacts Beard et al. Further, organic production systems occasionally conflict with regenerative philosophies, making regenerative almond systems a rarity within the industry.
Ground cover may enhance the natural resource base of almond orchards in several ways. Exposed soils erode and lose soil carbon Kosmas et al. The loss of carbon via soil erosion negatively affects land and water quality, reducing yields Lal, ; Lal et al. Twenty percent of the eroded SOC is mineralized and released into the atmosphere in a gaseous state 0.
Bare orchard floors eliminate critical habitat and resources that support beneficial invertebrates and microbial populations Eilers and Klein, ; Paredes et al. Allowing for ground cover and reducing soil disturbances in vineyards increases microbial biomass Ingels et al. Increasing vegetation diversity increases invertebrate biodiversity in croplands Root, ; Lundgren et al.
Invertebrate diversity, abundance, and biological network interactions limit pest pressure through predation and competition, but also in ways that remain poorly understood Barbosa et al.
Further, increasing plant diversity in farmlands eliminates the yield gap between organic and conventional production systems Ponisio et al.
The impacts of increasing orchard floor vegetation coverage and reducing synthetic inputs in almond orchards involves complex chemical, physical, and biological factors which require systems-level scientific studies. This study compared established and successful regenerative and conventional almond orchards.
We hypothesize that practices that enhance soil health and carbon storage will also increase biodiversity. Specifically, we hypothesize that regenerative orchards will have higher levels of soil organic matter SOM , Total Soil Carbon TSC , lower soil bulk densities, higher rates of water infiltration, and more robust and diverse microbial and invertebrate populations LaCanne and Lundgren, ; Fenster et al.
We hypothesize that regenerative orchards will have reduced pest pressure relative to insecticide-treated conventional systems. Finally, we hypothesize that regenerative orchards will have lower yields while being more profitable.
We believe that this improved profitability will stem from a reduction in synthetic input costs as well as a greater market value for their product LaCanne and Lundgren, Overall, we do not believe these differences will be due to a particular management practice, but rather the interacting effects of stacked regenerative practices Fenster et al.
In four regenerative and four conventional orchards were sampled and in a new set of four regenerative and four conventional orchards were sampled. Regenerative and conventional orchard pairs were within The Web Soil Survey was used to select similar soil types for the conventional-regenerative orchard pairings NRCS, To further establish similar soil conditions between treatments in pairs soil samples were sent to the Oregon State Soil Lab, where the sand-silt-clay composition was determined via the hydrometer technique OSU, The clay percentages of the soils were considered as co-factors in all subsequent models that examined TSC.
The average age of the trees in conventional orchards was The ages of trees in regenerative orchards ranged in years from 8 to 38 y, while in the conventional orchards, trees ranged from 3 to 25 y.
All the orchards in the study were planted to at least two varieties to improve pollination Klonsky et al. Table 1. The regenerative matrix score is the sum of regenerative practices on each farm, as determined through grower surveys.
The treatments were defined by rankings derived from a character matrix of nine different practices that were considered as regenerative or conventional Table 1 LaCanne and Lundgren, ; Fenster et al. Engaging in a regenerative practice or abstaining from a conventional practice resulted in the farm receiving a score of 1 for that matrix category.
Therefore, the maximum regenerative score a farm could receive is 9. Use of organic amendments compost, manure, mulch, compost teas Bugg et al.
Using non-OMRI listed insecticides, herbicides, fungicides, and fertilizers forthwith referred to as synthetics inputs , bare soil, and tillage were all considered conventional practices, and received a 0 score.
Additionally, the literature suggests that OMRI approved fungicides containing copper have detrimental environmental effects Vukicevich et al. They do not biodegrade, thereby accumulating in agricultural soils Wang et al. Therefore, despite being OMRI approved, the use of fungicides containing copper resulted in orchards receiving a zero in the fungicide category.
Orchards that scored 5 or greater in our matrix were declared regenerative orchards, and those that received a score of 4 or lower were categorized as conventional orchards. A minimum of five regenerative practices was used as the regenerative threshold for two reasons.
First, there are five principles underlying regenerative agricultural systems: minimizing soil disturbance, eliminating or reducing agrichemical use, eliminating spatio-temporal bare soil events, maximizing plant diversity, and integrating livestock into a cropping operation Rodale, ; Rhodes, ; LaCanne and Lundgren, ; Gosnell et al.
Furthermore, in Fenster et al. These natural groupings could be divided at the score of 5. As a result, Fenster et al. In this study, all the orchards that qualified as regenerative were also certified organic. However, organic certification was not a requirement for a farm being defined as regenerative in this study, and organic orchards could be considered as non-regenerative.
Four study plots were established in each orchard. The plots were 40 × 40 m and separated by at least 15 m, resulting in 64 total observation points for the study. Plots were established 20 m into the field to avoid field margin effects. Smaller plots were used in one Capay Valley regenerative orchard and one Capay Valley conventional orchard approximately 30 × 15 m, 6 m margins due to the smaller sizes of these orchards.
Soil pH, soil macro, and micronutrients and Haney soil health scores were quantified in each orchard Ward Laboratories, Kearney, NE. Four soil cores 15 cm deep, 1. All samples were collected in the same week, and each regenerative and conventional orchard pair occurred within 24 h.
Soil cores for each orchard were combined in a sealed plastic bag and placed in a cooler with dry ice Franzluebbers et al. To determine SOM, the Loss on Ignition LOI technique was used.
Soil pH was quantified using the slurry method with a ratio soil: water Weil and Brady, Soil nutrients levels and the Haney Soil Health Score were measured on samples that were dried at 50°C. The samples were ground to pass a 2 mm sieve and divided into three subsamples two were 4 g each and one weighed 40 g.
The 40 g soil sample was incubated for 24 h at 24°C. This sample was wetted through capillary action by adding 20 ml of deionized water to a ml glass jar and then capped. After 24 h, the gas inside the jar was analyzed using an infrared gas analyzer IRGA Li-Cor A, LI-COR Biosciences, Lincoln NE for CO 2 -C.
The two 4 g samples were extracted with 40 ml of deionized water and 40 ml of H 3 A, respectively. H 3 A extracts NH 4 , NO 3 , and P from soil. The extractant, H 3 A, is made up of organic root exudates, lithium citrate, and two synthetic chelators DTPA, EDTA Haney et al.
The water and H 3 A extracts were analyzed on a flow injection analyzer Lachat , Hach Company, Loveland CO for NO 3 -N, NH 4 -N, and PO 4 -P. The water extract was analyzed on a Teledyne-Tekmar Torch C:N analyzer for water-extractable organic C and total N WEOC and WEON.
WEOC and WEON are the fraction of soil organic carbon and nitrogen present that is mobile and bioavailable to the microbial community Zsolnay, ; Zhang et al. The H 3 A extract was also analyzed on a Thermo Scientific ICP-OES instrument for P, K, Mg, Ca, Na, Zn, Fe, Mn, Cu, S, and Al Haney et al.
The Haney Soil Health Score provides a general estimate of the overall health of a soil system. The score combines five independent measurements of soil biological and chemical properties, consisting of NH 4 -N, NO 3 -N, WEOC, WEON, and 1 day CO 2 -C.
The calculation examines the balance of soil C and N and their relationship to microbial activity. Soil classification and surface bulk density BD samples were collected in three plots per farm, following the protocol outlined by the NRCS, These samples were collected during the fruiting period in and during the bloom period in A metal cylinder 7.
Wet weights of each soil core were recorded. The samples were then allowed to air dry for at least 40 wk at ~28°C. Soil samples were then microwaved to constant weight Usmen and Kheng, We compared the gravimetric soil moisture percentages for all the orchards as well as just the orchards, which were sampled in early March and therefore could not be affected by variations in irrigation regimes.
This weight was recorded to the 0. Bulk density is calculated by dividing the mass of the dry sample by the volume of the cylinder. The soil gravimetric moisture percentage was calculated by subtracting the dry weight from the wet weight and then dividing by the dry weight and multiplying by Sodium hexametaphosphate was added to the suspension and placed on a shaker overnight to overcome flocculation during settling.
Suspension was measured using a hydrometer in 1 L of water at multiple time points to determine the specific gravity of the suspension OSU, We determined that there were no treatment level biases in soil textures, pH, and clay percentages.
Water infiltration rates were measured twice per orchard in four regenerative and four conventional during the bloom and fruit development stages. Samples were taken from the middle of the tree row at randomly selected locations.
We followed the NRCS protocol, where ml of water was poured into a sheet-metal ring The time until all the water saturated into the soil was recorded to the nearest second. During the fruiting period in the Chico conventional orchard, the infiltration time assigned was 8, s with 1 cm of water remaining in the ring.
This process simulates an instantaneous 5 cm of rainfall Doran, The two samples were averaged for each farm. Soil samples were collected in each plot to determine TSC and total soil nitrogen TSN.
The probe 2. Each section of the core was placed into a plastic bag that was stored on ice until it could be transferred to a paper bag in the laboratory. Samples were weighed to the nearest 0. The air-dried weight of the soil was recorded to 0. All visible pieces of rock and organic matter were removed from the samples using tweezers, and the samples were ground using a sterilized mortar and pestle.
Samples were then passed through a sieve with 0. The samples were stored in manilla envelopes in a desiccator. Soil 12—15 mg was removed from the manilla envelope and placed into tin capsules 5 × 9 mm, Costech, Valencia, CA for elemental analysis. For each soil depth, three sub-samples underwent elemental analysis ECS , NC Technologies, Milan, Italy.
To calibrate the analysis, each group of samples on a multi-sample plate consisted of five bypass samples that removed any gas or residue from the machine 12—15 mg of soil , two blanks, and four standards, 0.
A standard was placed between every 10 soil samples to ensure accurate results. To control for the relative compaction and other circumstances associated with each vertical depth, the mass Mg of TSC per ha was assessed using the Equivalent Soil Mass ESM method, in which a cubic spline of Mg of TSC per depth layer was calculated Wendt and Hauser, Phospholipid fatty acid profiles were used to characterize the microbial communities.
Soil cores 10 cm depth, 1. All samples were collected within the same week; samples on each paired regenerative and conventional orchard occurred within 24 h.
The 16 soil cores for each orchard were combined in a sealed plastic bag and placed on dry ice Drenovsky et al. The microbial biomass and community composition were recorded as Total microbial biomass, Undifferentiated microbial biomass, Total bacteria, Gram-positive bacteria, Actinobacteria, Gram-negative bacteria, Rhizobia bacteria, Total fungi, Arbuscular mycorrhizal fungi, Saprophytic fungi, and Protozoa.
PLFA testing was performed by Ward Laboratories in Kearney, NE White, ; Zelles et al. The epigeal invertebrate communities were sampled using a 15 cm tall 0. The quadrats were placed at two random locations in the inter-row areas of each plot, and invertebrates collected were combined.
Sampling of the invertebrate communities occurred during the bloom, fruit development, and harvest periods. The biomass of the invertebrates per 0. Invertebrates were identified to the morphospecies level. Voucher specimens are all housed in the Mark F.
Longfellow Biological Collection at Blue Dasher Farm, Estelline, SD, USA. Percent ground cover was assessed using visual assessments in each invertebrate quadrat Hanley, The community composition and whether the ground cover was resident vegetation or planted was determined using information from farmer surveys and direct field observations.
We used pest damage to almonds collected from the orchard floor as an indicator of pest incidence. Pest damage to the tree was not monitored, nor were actual pest populations scouted.
In , almonds were randomly collected from the orchard floor diagonally across each plot, and almonds from each farm were pooled across plots. The samples were collected identically in , but almonds were collected per plot and were analyzed per plot. The almonds were each categorized as having no pest damage, navel orange worm damage Amyelois transitella [Walker]; Lepidoptera: Pyralidae , ant damage Formicidae , oriental fruit moth damage Grapholita molesta [Busck]; Lepidoptera: Tortricidae , peach twig borer damage Anarsia lineatella Zeller; Lepidoptera: Gelechiidae , leaf footed plant bug LFPB or stinkbug damage Hemiptera: Coreidae, Pentatomidae , and unknown pest damage Bentley et al.
Regarding the no pest damage qualification, this designation was separated based upon the USDA standard for serious damage USDA, These designations were: zero pest damage and no serious pest damage still edible and would make a USDA grade.
The samples were collected identically in , except the almonds per plot were not pooled across plots. Joseph, MI. For the other nutrients, the ground almonds were digested with nitric and hydrochloric acid to burn off organic matter. Hydrogen peroxide was then added to dissolve any fats and oils within the sample.
The samples were brought to a high boiling point and then cooled under the hood. Once cooled, the samples were brought to volume, mixed, and filtered.
Finally, the digested samples were placed into test tubes and the nutrient levels were determined via inductively coupled plasma mass spectrometry Thermo iCAP ICP-OES Duo, ThermoFisher Scientific, Waltham, MA. A producer survey was used to determine management practices, costs, and revenues that contributed to the direct net profitability of each operation Supplementary Materials.
No farm in the study reported additional revenue from grazers or additional revenue streams such as almond hulls, but two regenerative orchards reported revenues from selling value added products, such as almond butter.
For the yield analysis, one conventional too young and one regenerative orchard information not supplied from the Capay Valley were not included.
The study used the lme4 package to create the General Linear Mixed Models GLMM Bates et al. To calculate the biodiversity indices we used the vegan: Community Ecology package Oksanen et al. For non-parametric statistical calculations and comparing models the study used the RVAideMemoire: Testing and Plotting Procedures for Biostatistics and the Modern Applied Statistics with S.
Fourth Edition packages Brian et al. For linear regression analysis and performing the Bonferroni Outlier Test, the analyses used the Companion to Applied Regression car package Fox and Weisberg, The R base package was used for the multivariate analyses and the micompr R package Fachada, was used to ensure the assumptions were met for those analyses Supplementary Materials.
The R package Rstatix Kassambara, was used to determine collinearity. Th R base package and ggplot2 Wickham, were used for the Principal Component Analysis PCA. MANOVA was used to confirm the patterns in soil and biological response variables that were revealed by our univariate assessments, and investigate whether or not collinearity among the response variables was a driver of these relationships Supplementary Table 1.
Principle Component Analysis PCA was used to assess the interactions among the soil quality and biological metrics, as well as the importance of management practices in determining those metrics.
Further, this analysis was used to determine whether our designation of regenerative and conventional orchards accurately distinguished the response variables we observed.
To evaluate the association between management practices with the first two components of the ordination, we conducted Spearman rank correlations. The False Discovery Rate correction FDR was used to adjust for multiple comparisons.
Similarly, Spearman rank correlations were used to assess the degree of association among the soil quality and biological metrics.
The data was mostly normally distributed, so Welch's paired t -test was used for those samples. The exceptions were: total Phosphorus, inorganic Phosphorus, organic Phosphorus, and available Phosphorus. For these samples neither the data nor the residuals of the one-way ANOVA model were normally distributed, so we utilized the non-parametric Mood's Median test.
Soil water infiltration rates were only measured on the eight farms sampled in All these variables were analyzed using one-way ANOVA. Total soil carbon and total soil nitrogen data was analyzed at the plot level, with GLMM's used to analyze the data.
To investigate how Total soil carbon and total soil nitrogen varied across soil depths in regenerative and conventional orchards, we ran GLMM's. These models were run for the 0—3, Mg and 0—6, Mg ESM depth layers. Most of these models used a Gaussian distribution with the Gauss-Hermite approximation set to 1 corresponding to the Laplace approximation; Bates et al.
However, when examining TSC and TSN between the 3,—6, Mg ESM layers the GLMM had to be built using a Gamma distribution. Additionally, the integer scalar was set to zero which optimized the random and fixed-effects coefficients in the penalized iteratively reweighted least squares step Bates et al.
Due to the current interest in utilizing regenerative management to sequester carbon we isolated the effect of each regenerative practices by analyzing the effect of all the regenerative management practices and soil clay percentage on TSC via multiple regression.
While the data itself tended not to be normally distributed, the residuals from the one-way ANOVA models tended to be normally distributed allowing for the use of one-way ANOVA for most of these analyses. Plant species richness was assessed using one-way ANOVA analysis and ground coverage was assessed using Mood's Median test.
This normalized the data allowing for the use of Welch's paired t -test to analyze this data. To analyze the relationship between invertebrate biodiversity and pest damage we built separate GLMM's. These models used a Gaussian distribution with Gauss-Hermite approximation set to 1 corresponding to the Laplace approximation Bates et al.
To analyze differences in nutrient levels and the distribution of nutrients within the almonds we used a GLMM. These models used a Gaussian distribution with Gauss-Hermite approximation set to 1 corresponding to the Laplace approximation; Bates et al.
This data was normally distributed, resulting in the use of Welch's paired t -test to analyze this data. Regenerative orchards contained higher levels of Water Extractable Organic Matter WEOM , which is comprised of WEON and WEOC. Regenerative orchards also had higher levels of total Phosphorus, inorganic Phosphorus, available Phosphorus, Calcium, and Sulfur.
Conventional orchards had significantly more aluminum than regenerative orchards. The soil quality index, Haney Soil Scores, were higher in regenerative orchards Figure 1. Table 2. Figure 1. The soils in regenerative orchards had lower bulk densities and more effectively infiltrated water.
The mean surface BD in regenerative orchards was 1. Gravimetric soil moisture percentage was higher in regenerative orchards when comparing all the orchards and when only the orchards were compared orchards in which we tested for water infiltration.
Figure 2. Water infiltration rates were measured once per orchards during bloom and fruit development in A smaller number means that water infiltrated into the soil at a faster rate. Regenerative orchards had significantly higher levels of TSC, TSN, through all the ESM strata 0—6, Mg ESM layers; Figure 3 ; Table 3.
Through the 6, Mg ESM layer, regenerative orchards contained 5. The TSC:TSN ratio in regenerative orchards through the 6, Mg ESM layer was 9. Figure 3. The differences in carbon and nitrogen through the 0—6, mg Equivalent Soil Mass ESM layer ~0—60 cm in regenerative and conventional almond orchards mean ± SEM.
Table 3. The differences in carbon and nitrogen at different soil depths in regenerative and conventional almond orchards. Total Soil Carbon and TSN varied by treatment among the different soil depths.
In the top 1, Mg ESM of soil, regenerative orchards had significantly more TSC and TSN, regardless of how much soil clay was present Table 3. Clay became a significant factor in determining TSC at the 1, Mg ESM layer, but with TSN, clay was not a significant factor until the 3, Mg ESM layer Table 3.
The greatest percentage of TSC was found at the 0— Mg ESM layer. The duration that these orchards had been in their respective systems had significant effects on soil carbon. Ground cover was the parameter best correlated with TSC through the soil column.
Conventional orchards never had greater metrics of microbial community structure than regenerative orchards. Table 4. The soil microbial community in regenerative and conventional almond orchards.
Figure 4. This sampling occurred during the fruiting period. Regenerative orchards had significantly more plant cover on the soil surface than conventional orchards. Additionally, regenerative orchards averaged more plant species on the floors of their orchards.
The mean number of plant species on the orchard floor in regenerative orchards was 7. We identified different invertebrate morphospecies arthropod morphospecies from almond orchards, totaling 12, individuals.
Larvae and adults were considered separate morphospecies, as adults and larvae serve distinct ecological functions Pecenka and Lundgren, Supplementary Table 2. The invertebrate species consisted of eight classes across 23 orders: Araneae, Blattodea, Coleoptera, Dermaptera, Diptera, Entomobryomorpha, Geophilomorpha, Hemiptera, Hymenoptera, Julida, Lepidoptera, Lithobiomorpha, Neuroptera, Oniscidea, Opiliones, Opisthopora, Orthoptera, Psocoptera, Solifugae, Spirobolida, Stylommatophora, Symphypleona, Thysanoptera.
The orders containing the highest number of morphospecies were: Coleoptera 99 , Hemiptera 39 , Araneae 36 , Diptera 30 , and Hymenoptera The most abundant orders were Entomobryomorpha 3, , Opisthopora 2, , Hymenoptera 1, , Coleoptera 1, , Oniscidea , Araneae , Diptera , Hemiptera , Dermaptera , Lithobiomorpha Invertebrate community structure was significantly different in the regenerative and conventional orchards.
Invertebrate biomass in regenerative orchards was 5. Invertebrate abundance in regenerative orchards was The mean arthropod abundance in regenerative orchards was Mean earthworm Lumbricina abundance in regenerative orchards was Figure 5.
Invertebrate communities were collected during the bloom, fruit development, and harvest periods. Regenerative orchards were significantly richer in invertebrate and arthropod morphospecies, while having more evenly distributed arthropod communities.
The mean species richness of all invertebrates in regenerative orchards was The mean species richness of arthropods in regenerative orchards was Pest damage was similar in regenerative and conventional orchards.
Using the stricter criteria of zero pest damage the mean percent of undamaged almonds in regenerative orchards was Without this outlier the mean percent of undamaged almonds in regenerative orchards increased to Using the less strict standard, no serious pest damage, the mean percent of almonds without pest damage in conventional orchards was Almonds in regenerative orchards contained higher levels of magnesium Table 5.
To better understand this difference, we ran a GLMM with years under regenerative management and years under conventional management as fixed factors. Regenerative orchards were approximately twice as profitable as conventional orchards Figure 6.
The profitability of regenerative orchards not accounting for value-added products was significantly higher in the regenerative orchards vs. Figure 6. A producer survey was used to determine management practices, costs, and revenues that contributed to the direct net profitability of each operation.
One conventional and two regenerative orchards were not included. Principal Component Analysis confirmed our distinct treatments, and revealed that nearly all management practices were correlated with improved soil and biological properties of the orchards. Almond shells are used as livestock bedding, and hulls are valuable dairy feed, with research underway exploring new potential uses in the areas of recycled plastics, fuel, and regenerative agriculture.
Next stop: the processor for sizing, where the almond kernels drop into separate bins according to size. After sizing, almonds are kept in controlled storage conditions to maintain quality until they're either shipped or further processed into a variety of different almond forms for diverse culinary uses.
And the biggest almond lovers are right here in the U. Almonds are enjoyed in many ways, occasions, and locations! From whole almonds to blanched, sliced and diced ones—as well as almond flour, paste, butter, oil, milk, and more—almonds are incredibly versatile, satisfying, and packed with powerful plant-based nutrition, supporting healthy diets the world over.

EOSDA Crop Monitoring Manage your fields with high-resolution peoduction images for the most accurate and timely changes detection!
Primarily, this is achieved through proper care practices like watering, fertilizing, controlling pests and diseases, and pruning. Despite their ability to grow in the dry heat of summer, these plants require consistent irrigation.
It is essential in growing conditions, where annual rainfall is less than 20 inches mm Hart, R. New Zealand Tree Crops Association NZTCA. Keep the soil moist but not soggy, since overwatering might cause fungal diseases.
Almond plants growing in California, for instance, consume an average of 47 acre-inches m3 of water annually. Accurate weather data on your site is essential for planning almond irrigation. The EOSDA Crop Monitoring platform provides precise agrometeorological information, such as historical temperature and precipitation dating back toas well as reliable day forecasts of wind speed, solar radiation, relative humidity, and other variables.
If you want even more specifics on growing conditions, you can connect nearby ground-based weather stations to the platform.
Start fertilizing your tree in the spring. Small, consistent applications of nitrogen fertilizer to almond trees throughout the growing season are beneficial for young plants, while older plants have a significantly lower fertilizer need.
After your tree has become established and begun bearing fruit, you may promote its growing success with a one-time application of 2 pounds 0.
To find out where and how much nitrogen N to give your growing trees, use the vegetation maps provided by EOSDA Crop Monitoring. Since excessive N-application poses the risk of leaching and polluting soil and water bodies, zoning an orchard according to vegetation indices and then applying variable amounts of nitrogen based on the needs of each zone would help optimize resource allocation and foster a more sustainable agriculture practice.
The navel orangeworm is the most prevalent insect that attacks almond trees. This worm overwinters in nuts that were left on the tree after almond harvesting. Taking all the nuts off the tree will deprive these pests of their food source and keep them away from your orchard. Given their susceptibility to numerous pests, almond growing farms require regular inspections to protect both the trees and their fruits.
But how can you easily locate a problem on a large plantation? EOSDA Crop Monitoring comes into play here, streamlining pest and disease detection and reducing the cost of it, especially in large-scale growing areas. The first step is to use vegetation indices on the platform to keep tabs on your plantation and spot any unusual shifts in plant health and density.
Then, if pests seem to be present, you can send a scout to this specific growing area to confirm or disprove the cause of concern. The best way to keep tree diseases at bay is to put up a strong defense.
Follow these steps to ensure your orchard remains disease-free:. When pruning a mature tree, your primary goal should be to preserve its existing shape. Pruning is a great way to revitalize a mature tree and boost its productivity.
Almond harvesting is a multi-step process that requires specialized machinery and techniques. The almond harvest season is typically early August through late September, though this differs per variety. Nuts that have fallen from the tree are another sign to begin harvesting.
How To Harvest Almonds When almond harvest time arrives, machines called tree shakers go through the orchard and shake the nuts out of the trees. After 7—10 days of air drying inside their shells, the nuts are swept into neat windrows by a specialized sweeper machine.
A harvester, aka a pick-up machine, then gathers the nuts by vacuuming them into a shuttle or cart. Almost every orchard goes through this cycle two to three times because different varieties are gathered at different times.
The work of a farmer does not stop when the crop is harvested. After all, the trees need further care so that they can produce nuts in the next growing season, and the nuts themselves must be processed and stored. Providing nutrients and water to your trees after they have been harvested is crucial to their long-term health and increased crop yield.
Post-harvest care that is both sufficient and well-balanced helps trees recover and prepare for the growing season. It fosters enhanced root growth and carbohydrate rebuilding, as well as vigorous flower formation and leaf expansion in the next growing season.
After being harvested, almonds arrive at a huller facility, where they are cleaned by rolling over a grate. Clean nuts are size-sorted by a sizing machine and then kept in temperature- and humidity-controlled storage until they are needed for further use.
Is growing almonds bad for the environment? Since the trees require a lot of water to develop, they contribute to the spread of drought in places already vulnerable to water shortages, where they typically grow.
Another major issue is the extensive use of agrochemicals. Many of them pose threats to pollinators like honey bees and wild bees. Agrochemicals promote soil erosion and the loss of fertile topsoil. Furthermore, these pollutants may leach into the soil and water, causing damage to the local ecosystems.
On top of that, almond tree growing is a contributor to greenhouse gas GHG emissions. Almonds: Health, Cultivation, and Sustainability. Open Science, MDPI. The upside is that scientists and farming experts constantly attempt to find remedies to these issues, and some of them already have solutions.

: Almond production| Almond production | New branded products and new uses of almonds in cereals, ice cream, confectionaries and baked goods have been introduced. Another new use for almonds is processing the not-yet-ripe kernels of green almonds. They are harvested early, and the liquid kernels are used by chefs at gourmet restaurants to add a delicate taste to high-end dishes. Almonds are either sold as in-shell or as processed, which can include shelling, dry roasting, blanching, slicing, and chopped and converted into paste marzipan or flavorings. The majority of almonds are shelled during processing, and the excess casings the hull and shell are used in the livestock industry for both feed and bedding material. The United States is the dominant supplier of almonds. Nearly 70 percent of U. almonds are exported as shelled almonds, with the remainder being either unshelled or manufactured. The United States imported Almond Almanac , Almond Board of California ABC , - This annual publication summarizes the production statistics of the California almond industry. National Agricultural Statistics Service NASS , The U. ABC provides tools to California almond growers based on ABC-funded research on ways to reduce harvest dust to improve air quality.

Water Availability California almond growers are focused on responsible and efficient water use as water is often a limited resource, The Irrigation Improvement Continuum, launched in and based on ABC research and expert advice, is a mechanism for growers to improve water use efficiency. Each almond variety is harvested separately, so this process typically happens two to three times per orchard. Almond farmers practice a zero-waste approach , ensuring everything an orchard grows is put to use. Almond shells are used as livestock bedding, and hulls are valuable dairy feed, with research underway exploring new potential uses in the areas of recycled plastics, fuel, and regenerative agriculture. Next stop: the processor for sizing, where the almond kernels drop into separate bins according to size. After sizing, almonds are kept in controlled storage conditions to maintain quality until they're either shipped or further processed into a variety of different almond forms for diverse culinary uses. And the biggest almond lovers are right here in the U. Almonds are enjoyed in many ways, occasions, and locations!

| Regenerative Almond Production Systems Improve Soil Health, Biodiversity, and Profit | Taxon identifiers. To accomplish this, regenerative orchards replaced synthetic agrichemical inputs with more robust microbial communities, diverse ground covers, organic amendments, and invertebrate diversity that increased soil nutrient levels, made more water available to the trees, and managed pest pressure to a similar level. Soil pH, soil macro, and micronutrients and Haney soil health scores were quantified in each orchard Ward Laboratories, Kearney, NE. Chaplin-Kramer, R. To our knowledge, this is the first published examination of relative nutritional contents of regenerative farm products. |
