EVOLUTION N 7 is a new formulation in the Evolution line, characterised by an organic nitrogen content (N 7%) derived from dried blood and complex organic protein matrices, which ensure a gradual and prolonged release of nitrogen over time. The special composition optimises its efficiency and reduces leaching losses, suitable for use on all crops, both herbaceous and tree crops. The product is highly recommended for use as a top dressing for spring crops with high nitrogen requirements (e.g. maize, rice), as well as for open field and protected crops. EVOLUTION N 7 is also particularly suitable for tree crops such as orchards, vines, olive trees and nut crops, both after harvesting and for fertilisation at the end of winter. It is also suitable for use in nurseries and new plantations, being an ideal product for organic farming.
