STUDIES ON THE USE OF ROM-AGROBIOFERTIL NP FERTILIZER IN DIFFERENT CROPS AND IN DIFFERENT AREAS IN ROMANIA STUDII PRIVIND UTILIZAREA INGRASAMANTULUI ROM-AGROBIOFERTIL NP IN CULTURI

Abstract

The researchers created a biofertilizer - Rom-Agrobiofertil NP - consisting of a mixture in equal parts of three live germ cultures: Azospirillum lipoferum, Azotobacter chroococcum and Bacillus megaterium. Embedded in the soil, the three bacteria enter into a partnership with the plants and act synergistically to provide the nitrogen and phosphorus necessary for their development through complex mechanisms: accelerating the decomposition of plant residues, greening the soil through the decomposition of chemical fertilizer residues, fixing atmospheric nitrogen, the metabolism of insoluble phosphates into easily assimilable soluble forms, the production of bacteriocins (antibiotics) as well as substances with antifungal action. The product is presented as a set of three components in liquid form, which are mixed together, diluted with water and can be administered by spraying on the soil surface. This study presents the results obtained in testing Rom-Agrobiofertil NP for increasing productivity in different areas of the country. The testing concerned 2 crops: potato and corn.
