Often our western soils have a problem with many of the 42 essential elements of plant nutrition being inhibited by the alkaline chemistry of the soil. This simply means that the elements such as iron, zinc, copper, calcium, etc, etc, etc, are cemented into the matrix of the soil by way of a precipitation reaction called concretion. This is where the term ‘Concrete’ comes from, where the mineral elements are not soluble with just water. The process of getting these elements available for plant uptake requires a “solutioning” of the elements from the concreted soil, which is provided by the supramolecular chemistry of the organic matrix of humic molecules, and by the mycorrhizal fungi that are hopefully also present. It’s one of the Mechanisms of Action for the Humic Molecules and the Mode of Action for the Mycorrhizal fungi. Another limiting factor is the availability of nitrogen in the form of amino acids, caused by a slow or weak Soil Food Web. The SFW is the Terrest
