Evaluación del potencial de los microorganismos del suelo para mejorar el desarrollo agrícola

Abstract

Abstract: The rhizosphere hosts a rich microbial flora that contributes greatly to the nutrition and health of all plants, favoring access to nutrients or protecting from pathogens. The objective of this paper is to investigate the effect of biological interactions between plants of three agricultural crops and microorganisms of local soils little or nothing disturbed anthropically for their potential application in the sustainable improvement of local agriculture. We have investigated the bacterial and fungal diversity of two ecosystems, wet forest floor in Podocarpus and dry forest in Paltas. The taxonomic composition of bacteria and fungi was higher in Podocarpus (55.27% and 80.40%, respectively) than in Paltas (33.81% and 38.48%, respectively). Three blocks of 15 plants per species and variety per treatment were prepared. Then, throughout the crop cycle, agromorphological and phenological characters were evaluated. The inoculated plants exhibited the characters with significantly higher values and, between both inocula, the inoculum Paltas produced better results. Finally, the results obtained contribute a fundamental knowledge to understand the role that this diversity can play in promoting sustainable agriculture.
