STALFERT N 5 is a blend of organic nitrogen fertilisers with an organic nitrogen (N) content of 5%, made with organic protein compounds that provide a high level of humified carbon (C), which contributes a high content of humic and fulvic acids. It also contains iron (Fe), calcium (Ca) and magnesium (Mg) chelated to organic matter, which promote the development of bacterial flora and increase overall nutritional efficiency. STALFERT N 5 is particularly suitable for the formulation and enrichment of growing media thanks to its humified organic matter content. It is ideal for the pre-planting and planting phases of orchards and vineyards, horticulture and protected crops.
