Complex fertilizers are multi-nutrient made of nitrogen (N), phosphates (P) and potassium (K). The individual composition is taylor made to best meet crop demands and contents for example minerals and trace elements.
Besides the main ingredients nitrogen (N), phosphates (P) and potassium (K), NPKs could be consist of Sulphur (S), magnesium (Mg), copper (Co), zinc (Zn), boron (B) or chloride (Cl).
In order to boost agricultural yields further in response to the world’s growing population, compound fertilizers of increasing complexity are entering the market. Depending on the specific plants to be cultivated, minerals and trace element must also form part of the mix. These protect the plants against nutrient shortages, and also help make them more resistant. NPKs make it possible to adapt soil nutrients levels to best meet the plants’ requirements.
