Soil

While all of you should be well aware of the value of the biological components of our products (i.e., mycorrhizal fungi and rhizosphere bacteria), many of you may not fully comprehend the value of some of the other ingredients, like humic acids.

There is a lot of negative innuendo about sodium content is soil, and as a result, many assume that sodium is somehow very toxic. In fact, it is not the sodium itself that causes the problem. It is the amount of salts in the plant tissue or in the soil around the roots and the effect they have on water uptake that causes problems.

Soil is considered fertile if it is productive, that is, if it can support lush healthy growth of desirable plants, whether they be garden plants, landscape plants, or crops. But what makes soil fertile? What characteristics of soil determine whether it will be productive or not? This question has been asked repeatedly for many years. Here is a summary of our current understanding on this topic.

Leaching refers to the event whereby a material (such as a fertilizer) dissolves in the soil water and moves away, ultimately into groundwater or surface water. All soluble materials, including fertilizers, can leach. The real question is whether a fertilizer leaches rapidly or slowly. If leaching is very slow, then the chances are good that most of the fertilizer will eventually be consumed by the local plants and animals, leaving very little to can escape into the ground water. If leaching is very fast, then there is little time for the fertilizer to be consumed locally, thereby allowing a large percentage of it to rinse through the soil and into ground water.
