Mineral inputs to improve soil fertility

摘要

In the quest for biological farming, much emphasis is placed on the need for mineral balance in the soil in addition to, and many would say as a prerequisite for, biological soil fertility. Whether for plants or livestock (and humans who eat them), mineral ratios and assimilation to form proteins, amino acids and vitamins, etc, are very important. The goal of biological soil management is to achieve adequate levels of available nitrogen, phosphorous and potassium and for the cation exchange to comprise calcium, magnesium, potassium, sodium and hydrogen in the desired proportions, which in turn allow maximum nutrient availability to plants, increased plant vitality and high brix levels (sap sugar levels) with reduced susceptibility to insect attackdue to lower sap nitrate levels.
