DERMAFERT NPK 10-10-15 NBPT is an organo-mineral NPK fertiliser obtained through a reaction between mineral components and organic protein matrices, using a coextrusion technology, which optimise the integration and the stability of different fractions of the formulation. The use of the inhibitor NBPT is an innovation element, capable to delay the hydrolysis of the ureic nitrogen, reducing nitrogen losses. The product is a complete fertiliser, as it combines organic nitrogen with slow mineralisation, ureic nitrogen stabilised with NBPT and ammoniacal nitrogen. This combination ensures a progressive, differentiated and constant nutritional supply throughout the entire cropping cycle. In addition, DERMAFERT NPK 10-10-15 NBPT contain high level of potassium and phosphorous from sulphate, both fully available by plants and complexed with the organic matter, which, reduces insolubilisation processes. The product is suitable for all soil, resulting particularly effective in soil with high pH value and low organic matter content. It is recommended for autumn and spring basal fertilisation, as well as maintenance fertilisation of orchards, vineyards and vegetable crops. The formulation is also suitable for use in grassed systems or in conditions where soil incorporation is not possible.
