Trionem S Greenfer Plus is a revitalizing base fertilizer for tired and depleted soils, unique on the market as it is characterized by the presence of three types of plant cakes: Brassicaceae, Meliaceae and Liliaceae (hence the prefix Trio in the name of the product), and from two exclusive production technologies: Foamtechnology and Microzym Trio. The product provides a high content of highly humified organic matter, stable and with an optimal C/N ratio, which increases long-term fertility and nourishes the useful microbial population of the soil. These are precisely the microorganisms of the exclusive Microzym Trio production technology: Thermoactinomyces spp., Streptomyces spp. and Bacillus spp., to degrade the organic substance and to produce a series of volatile compounds that restore soil fertility. This is also thanks to the Foamtechnology component which, in contact with water, generates a micro-foam that oxygenates the soil making it more hospitable for the plant and its roots. Finally, Trionem S Greenfer Plus provides Iron and micronized elemental Sulfur which reduce the incidence of deficiency phenomena in plants and, by acidifying the circulating solution of the soil, increase the amount of nutrients available to the plant.
