Fertilizers are fundamental practices for the nutrition of the plants we grow and for the improvement of the soils we use for crops. There are several types of fertilizers, chemical and natural fertilizers can be used. Chemicals are fertilizers derived from chemical reactions and industrial processes; Naturals, on the other hand, are fertilizers derived from substances found in nature. Fertilizers are further divided into simple fertilizers and complex fertilizers, complex fertilizers are composed of three elements (ternary) or two elements (binary). Basically, the elements that make up fertilizers are nitrogen, phosphorus and potassium. Among the binary fertilizers is also the fertilizer 18 46 known as “diammonium phosphate”.

the diammonium phosphate It is made up of two elements: nitrogen and phosphorus. Nitrogen is present in the form of ammonia in a percentage of 18%; phosphorus, on the other hand, is present in greater quantity, at 46%. the fertilizer 18 46it has a solid, grainy consistency and is brown in color. The decomposition of this fertilizer only occurs in environments where the temperature exceeds 150°C. Despite its solid consistency, it is possible to dissolve it in water even if it releases quantities of insoluble substances. The advice, however, is not to use it with contextual irrigation fertilizations. This type of fertilizer is part of the slow-release fertilizers, in fact the nitrogen is in the form of ammonia and therefore the ammonium ion is metabolized by the bacteria present in the soil and then transformed into proteins.
18 46 Fertilizers: uses
Generally, this type of fertilizer is used to fertilize cereals. More than anything else, it is used for the fertilization of the bottom, or those relating to the soil. Some growers use the 18 46 fertilizer for double fertilization: the first is the soil and the second is the one used during cultivation. In this way, the beneficial effects of nitrogen in the planting phase and phosphorus in the cultivation phase are utilized. In regions with very high temperatures, it is recommended to use this fertilizer in a single solution during the pre-sowing or pre-sowing phase. The doses of this type of fertilizer to be administered to the plants must be established according to three situations: the type of crop, the climatic conditions and the characteristics of the soil used.
