Fertilizers are fundamental practices for the nutrition of the plants we cultivate and for the improvement of the soil we use for crops. There are various types of fertilizers, both chemical and natural fertilizers can be used. The chemical ones are the fertilizers that derive from chemical reactions and industrial processes; the natural ones instead are fertilizers that derive from substances present in nature. Fertilizers are further divided into simple fertilizers and complex fertilizers, complex ones are composed of either three elements (ternaries) or two elements (binaries). Basically the elements that make up the fertilizers are Nitrogen, Phosphorus and Potassium. Among the binary fertilizers there is also the fertilizer 18 46 known as «diammonium phosphate».

The doses of this type of fertilizer to be administered to the plants must be established on the basis of three situations: the type of cultivation, the climatic conditions and the characteristics of the soil used.
