Complex granular fertilizer with prolonged action. It restores soil fertility, promotes intensive tuberization of potatoes with excellent taste characteristics and long shelf life. The uniqueness of the fertilizer lies in the fact that it combines the best properties of both organic and mineral fertilizers. The ROSOMU technology allows you to preserve all the nutritional value of organic matter (several times higher than compost) and to ensure the assimilation by plants of up to 90% of mineral elements (ordinary mineral fertilizer is absorbed by 35%). Organic matter 70-85%, NPK 9: 8: 11 + 2.5% MgO + S + Fe + Mn + Cu + Zn + B.
