Organic mineral choices -
The organic forms are supposed to minimize the interactions and enhance the absorption and bioavailability of minerals Liu et al. However, greater bioavailability of organic minerals does not always result in improvements in growth Creech et al.
Typically, the use of organic mineral sources is more prevalent in diets for sows and nursery pigs Flohr et al. Decisions on which source of mineral to use should be based primarily on price per unit of bioavailable element, with organic minerals usually being more bioavailable but inorganic minerals are typically more economical.
A list of the chemical forms in which inorganic macrominerals and trace minerals are available is shown in Table 1 and Table 2 NRC, These minerals are all essential to the proper growth and development of your livestock.
A trace mineral colloidal silicate which contains a combination of nearly 50 mineral compounds. It can be fed free choice, used as a top dress, or mixed in a TMR. It can improve the nutrition, health, and profitability of all the animals on your farm.

Now that we are well versed in the definitions, let us look at each one as it relates to selecting parts and components for growing systems. Plant roots can be selective in what elements they let through the cell membranes and into the plant itself.
It is a system comprised of many components that work by allowing access for all elements smaller then a particular size by diffusion; actively moving very specific molecules such as nitrate or larger single elements; or other varied methods.
Mineral elements are the ones that will break down and be available faster then anything else. Since all elements, including those applied organically, must exist as a single element to cross into a cell excluding specialty molecules , and organically applied components are still complex molecules waiting further breakdown into usable end products, Synthetic Inorganic minerals will react quicker with a plant and can be controlled more precisely.
They are supplied in many combinations like Ammonium Nitrate, Calcium Nitrate, Potassium Sulphate, or Potassium Phosphate, ions that disassociate in solution and the plant can take them up.
This is especially true where heavy metals are concerned. These undesirable elements can either be deposited into the medium causing salt and other toxicity problems, or pass into the plant to be deposited into the cell vacuoles where they remain until consumed by the end user or degrade into the soil.
Organic, as the term is used in the Green Industry, implies two basic concepts. One is material based as in the source of Nitrogen is an organic molecule, and contains Carbon as noted earlier, that has to be broken down to be available. It also refers to the end product, plant or fruit, harvested or used, for example; the lettuce is Organic which means everything done to the crop was done with all Natural and Organic programs for feeding, pest control, etc.
Let us understand that a combination product like a fertilizer can have organic components with mineral elements combined and be either Organic or not, depending on both components.
Organic components are recognized as either synthetic or natural; they are either man made or not. When the subject is fertilizer, for instance, typically it is the Nitrogen that is worked with and everything else is incidental.
Natural Organic Nitrogen is sup- plied by whole components of once living things from plant to animal; components such as manure, leaf mold, or blood meal. These require organisms to finish the breakdown so they, too, must be present and the Nitrogen becomes available slowly.
Synthetic Organic Nitrogen includes compounds such as Urea, or Urea formaldehyde UF that release based on microbes, temperature, pH or other conditions of the medium. This Nitrogen is available fairly rapidly although some breakdown must occur. There are advantages to any of these and disadvantages, the faster they are available, the less time they spend available to the plant and the greater the chance of burn.
Also, to fit into the Organic Program, they have to be Natural Organic. The remaining component supplied elements are almost incidental in their presence in the fertilizer mix. Only by carefully selecting the most suitable feed stock for decomposition, selecting or designing the right microbes to break down the feed stock, and by engineering the pathway of decomposition can an organic fertilizer, such as BIOCANNA Bio Vega and Bio Flores for example contain a specific and known nutrient value.
If the other main components of a fertilizer are needed to make it complete, then it has to be added to the Nitrogen mix, or added separately.
Using a blend of plant and animal derived components will get close to all the required elements, but not for all. Certain components like Calcium are needed in large amounts but consumed in the degradation process. Bone meal can be added for the additional Phosphorous needed, but not for all organic consumers, some want no animal by-products to be used as well.
The next best option is to supplement what is needed to get the ratios correct, with naturally available elements such as Calcium Carbonate Lime or Rock Phosphate. As noted earlier, this same description, Natural and Organic, could apply to a Synthetic Organic Nitrogen and heavy metal contaminated Rock Phosphate.
Confused yet? So, as a review, we see that the term organic means many things and the same thing, so does natural, and yet both can be used at the same time to achieve better results.
What to do? A grower needs to understand a few important points first:. Certain components exist in almost all natural mineral soils fit to grow in, why grow in pure organic? Important components like Calcium are supplied in lime, phosphorous exists in all soils too, either as bound or as free, phosphate is the oxidized form and occurs in all mineral soils most is bound up in Calcium — Phosphate interactions and remains unavailable.
