DERMAFERT NP 11-25 is an organo-mineral NP fertiliser obtained through a reaction between mineral components and organic matrices, aimed at stabilising and protecting phosphates from soil insolubilisation, thereby ensuring greater availability of the phosphorus over time. The main characteristics of DERMAFERT NP 11-25 are: the presence of organic nitrogen with slow natural release, which ensure a gradual and constant release of nitrogen and a progressive availability of the other nutritive elements; high level of phosphorous, both mineral and organic; high content of organic matter (15%), derived from different matrices of natural origin. This composition promotes a gradual release of nitrogen, increases the agronomy efficiency of fertiliser unit and improves the biological fertility of the soil. The high quality of the matrices used and the excellent agronomic efficiency of the formulation permit to obtain high level of the yields, with reduced management costs and a lower environmental impact, thanks to a more rational use of the elements. The fertiliser is recommended for basal and in pre-sowing application in cereals, as well as during the establishment and the production phases of fruit trees and vineyards. It is also particularly suitable for localized application on sugar beet, especially in soil well supplied with available potassium.
