FERTIFIELD NP 7-14 BIO is an organo-mineral NP fertiliser obtained through a reaction between mineral matrices and organic protein components, which ensures the protection of phosphates against insolubilisation processes and increases their availability to crops. FERTIFIELD NP 7-14 BIO is a formulation based on exclusively organic nitrogen with natural slow release, derived from meat and bone meal, hydrolysed leather and hides, which ensures a progressive and constant nutrient supply throughout the entire crop cycle, and also contains assimilable phosphates and calcium. The combination of these characteristics makes the product particularly suitable for acidic or sub-acidic soils with a good supply of available potassium, as well as for soils deficient in phosphorus. Moreover, FERTIFIELD NP 7-14 BIO shows high agronomic efficiency of the fertiliser units, making it possible to achieve higher nutrient yields while simultaneously reducing environmental impact and fertilisation costs. The product is ideal for autumn and spring basal fertilisation of cereals and for the planting phase of fruit crops and vineyards, especially in soils with a good potassium supply.
