However, the effects have not been measured tangibly. This research permits us to: i) evaluate in the medium term the effects of the systems of tillage, cover crops and maize rotations by the physical, chemical, and biological soil characteristics, ii) determine the effect of the best management practices of soil for maize yields, iii) conduct an economic analysis of the implementation of tillage, cover crops, and rotation.text/plaines-ESIn CopyrightConservation agricultureSoil conservationSoil qualitySoilEconomic impactsConservation tillageFarm/Enterprise ScaleEvaluación de sistemas de labranza, cultivos de cobertura y rotación con maíz duro (zea mays l.) en la microcuenca del río Alumbre, cantón Chillanes, Provincia BolívarEvaluation of systems of tillage, cover crops and rotation with maize in the Alumbre river watershed in Chillanes, Bolivar ProvinceAbstract
