Sometimes plants are not able to capture nutrients even though they are present in the soil. The problem is that they are not in chemical forms assimilable by the plant, or that the pH of the soil is not adequate. In these cases, it is useless to add more nutrients to the soil, but to find the most appropriate way to transform these nutrients into forms that can be assimilated by the plant.
Certain microorganisms perform the natural function of transforming non-assimilable inorganic molecules into others easily assimilated by the plant’s root. Therefore, solid humus is an excellent soil unblocker. They can also decontaminate, that is, modify toxic substances present in the soil, in other harmless ones for the crop.
