ABSOLUTELY ALL SOURCES OF PLANT NUTRITION come from MINERALS, with the exception of nitrogen (N), derived from the synthesis of atmospheric ammonia nitrogen (NH3).

At first, however, the large companies condemned the use of minerals in agriculture, because their profits were significantly lower than with the sales of chemically modified products; that is, a mineral works similar to any chemical fertilizer - only CHEAPER..

Once a mineral is integrated into the earth and put into solution, the plant takes advantage of it in the same way as a chemical, since it feeds on the basis of differentials in the saturation of the soils. In other words, the plant is nourished by cations and anions, so it is essential to have a suitable temperature, humidity, pH and Cation Exchange Capacity for complete nutrition - whether by means of chemical, biological and / or mineral products.
