The first 13 elements (with the exception of titanium), which are most often found in the earth’s crust, are part of the organic matter of plants, participate in all vital processes and play an important role in soil fertility. A large number of elements involved in chemical reactions in the bowels of the Earth, leads to the formation of a wide variety of compounds
