FERTIFIELD NK 8-20 is an organo-mineral NK fertiliser obtained through a reaction between mineral matrices and organic protein components. The product is characterised by a high level of organic nitrogen derived from slowly mineralising scleroproteins, integrated with synthetic nitrogen and potassium. The specific proportion of fertilising elements makes FERTIFIELD NK 8-20 particularly suitable for cereal fertilisation (rice, maize, wheat), as well as for other herbaceous and forage crops. It can also be used for autumn fertilisation of orchards and vineyards, including under permanent grass cover. It is recommended for soils with a good level of available phosphorus; in fact, the consistent use of FERTIFIELD NK 8-20 over time contributes to rebalancing the availability of the main soil fertility elements. Its high nutrient content makes the product competitive compared to common NK compound fertilisers.
