FERTIFIELD NP 20-10 NBPT is an organo-mineral NP fertiliser obtained through a reaction between mineral components and organic protein matrices, carried out with a coextrusion process that optimises the interaction between the organic and mineral fractions. FERTIFIELD NP 20-10 NBPT is characterised by organic nitrogen with natural slow release, derived from high-quality protein matrices; ureic nitrogen with NBPT, a urease inhibitor that delays urea hydrolysis and significantly reduces nitrogen losses; assimilable phosphorus that becomes progressively available thanks to complexation with the organic fraction; and organic matter of protein origin. The use of NBPT represents an innovative element, ensuring greater nitrogen use efficiency and prolonged nutrient availability over time. FERTIFIELD NP 20-10 NBPT makes it possible to apply dosages specific to the actual needs of crops, optimising yields and management costs. It also contains phosphoric anhydride (P₂O₅), which, thanks to its interaction with the organic protein matrix, is made available to plants throughout the crop cycle. The use of FERTIFIELD NP 20-10 NBPT is particularly recommended in alkaline soils, in soils with low buffering capacity, and in those with a reduced organic matter content. The product is recommended for sowing autumn–winter cereals, such as common and durum wheat, as well as for spring and row crops including maize, sorghum, sunflower, oilseed rape and sugar beet. It is also used in industrial vegetable crops such as tomato, artichoke and spinach. It is of particular agronomic interest for tree crops such as citrus, olive and hazelnut.
