Development of new eco-friendly biofertilizers based in microorganisms which, through sustainable strategies, enhance crop productivity reducing the environmental impact. In Naturbec we have developed Genesys and Nitrogénesys from selected microorganisms to reduce the use of chemical fertilizers. The strains included in them are able to fix Nitrogen, solubilize phosphorus and mobilize potassium that are not bioavailable. To ensure the optimal conditions for microbial activity, and to maximize the effect of biofertilizers, we have developed Tango, a prebiotic with high content in organic matter, humic extract, amino acids, and phytohormones from seaweed. Thereby, fertility of deteriorated soils by an excessive use of chemicals is regenerated, promoting more ecological methods and circular economy practices in agriculture.
