FERTIFIELD NP 8-15 is an organo-mineral NP fertiliser obtained through a reaction between mineral components and organic protein matrices, designed to maximise the protection of phosphates against insolubilisation. The product is specifically recommended for basal and pre-sowing fertilisation of cereals and leguminous crops, thanks to the presence of organic nitrogen with natural slow release, which ensures a gradual and constant nutrient supply during the early stages of vegetative development. The high content of phosphoric anhydride (P₂O₅) from mineral and organic origin, together with the presence of calcium (CaO) and a significant portion of organic matter (18%) derived from selected protein matrices, gives FERTIFIELD NP 8-15 a high agronomic efficiency.
