FERTIFIELD NP 6-3 is an NP organic fertiliser obtained from meat meal, bone meal, leather and hydrolysed hides. The product contains organic nitrogen (N) with slow mineralisation and phosphorus (P) from organic origins, which are both permitted in organic farming. The protein and phosphate matrices ensure a gradual and constant release, improving the efficiency of the fertiliser units. It is particularly suitable for basal and maintenance fertilisation of orchards and tree crops. The balanced ratio of nitrogen and phosphorus gives the product versatility of use, even in mid to long-cycle horticultural crops. FERTIFIELD NP 6-3 is suitable for autumn and spring applications, even without of soil incorporation, thanks to the organic protein form of nitrogen, characterised by reduced susceptibility to leaching. It is specifically used for fertilising olive trees, vineyards, pome fruits and stone fruits, particularly in the post-harvest phase or during vegetative regrowth at the end of winter. It is also suitable for floriculture, both before transplanting and when planting young plants. It can also be used for pre-sowing fertilisation of autumn-spring cereals.
