EFECTOS DE LABRANZA Y BIOFERTILIZACIÓN EN PROPIEDADES DEL SUELO QUE AFECTAN A LA SOSTENIBILIDAD DE LA PRODUCCIÓN DE FRIJOL EFFECTS OF TILLAGE AND BIOFERTILIZATION ON THE SOIL PROPERTIES AFFECTING SUSTAINABILITY OF THE DRY BEAN PRODUCTION EFECTOS DA LABRANZA E BIOFERTILIZACIÓN NAS PROPIEDADES DO SOLO QUE AFECTAN A SOSTEÑIBILIDADE DE PRODUCCIÓN DE FRIXOL

Abstract Resumen Resumo Dry beans (Phaseolus vulgaris L.) is an alternative of production in a cereal-legume crop rotation because improves profitability and fixes atmospheric nitrogen to soil. Different tillage practices that leave crop residues on the surface, and minimally alerts composition, structure and natural biodiversity of soil are used to conserve the agriculture ecosystem. Biological fertilizers using vesicular-arbuscular mycorrhizal (Glomus intraradices) constitutes a feasible alternative that might complement or even replace chemical fertilizers. the objetive of this research was to evaluate the effect of tillage systems and biofertilization as sostenibility practices in the dry beans production. Four tillage treatments were evaluated; moldboarb plow, subsoil-bedding, shred-bedding and no-tillage (control) and two fertilization treatments: chemical fertilization (40-20-00) and biological fertilization on some soil sustainability indicators. Tillage treatments that acumulated of crops residue...
