STALFERT TOP N 2.5 BIO ACTIVE is a high-quality mixed growing substrate, obtained using selected raw materials that are tested and certified at every stage of the production process. The organic plant matter, characterised by a high humification rate, works in synergy with horse and bovine manure to improve soil fertility. STALFERT TOP N 2.5 BIO ACTIVE is also characterised by a pool of microorganisms that include mycorrhizae (Glomus spp.), rhizobacteria (Bacillus subtilis OG39365) and Trichoderma harzianum OG99566. These microorganisms, present in high concentrations, play a crucial role in root system development and in improving nutrient absorption. Their use is recommended on horticultural and fruit crops, both in open fields and in protected cultivation, and is particularly suitable during transplanting and seedbed preparation.
