DERMAFERT NPK 6-12-10 is a complete organo-mineral NPK fertiliser, obtained through a reaction between mineral matrices and protein components, capable to providing organic, ureic and ammoniacal nitrogen to the crops, ensuring a progressive, differentiated and constant nutrient supply during the entire vegetative and reproductive cycle. DERMAFERT NPK 6-12-10 is characterised by a high content of potassium from sulphate, highly available, and by an amount of phosphorus protected by the organic matter, which reduces insolubilisation processes. It can be used in potassium deficient crops (sugar beet, vegetable crops), in potassium deficient soil, and it is strongly recommended for fruit crops, vineyards, walnut and hazelnut.
