Effect of different cover crops on C and N cycling in sorghum NT systems
(2016)In many no-till (NT) systems, residue input is low and fallow periods excessive, for which reasons soil degradation occurs. Cover crops could improve organic matter, biological activity, and soil structure. In order to ... -
Estudio de la contribución de nitrógeno por parte de los cultivos de cobertura al cultivo de maíz
(2013-03)El principal objetivo de este trabajo fue determinar los efectos del centeno como CC y del manejo de la fertilización nitrogenada del mismo, sobre la producción de grano y absorción de N de un cultivo posterior de maíz en ... -
High quality residues from cover crops favor changes in microbial community and enhance C and N sequestration
(2016)The objective of the study was to evaluate the effect of a change in management on the soil microbial community and C sequestration. We conducted a 3-year field study in La Pampa (Argentina) with rotation of sorghum (Sorghum ... -
Raíces de cultivos de cobertura. Cantidad, distribución e influencia sobre el n mineral = Cover crop roots: quantity, distribution and influence on soil mineral n
(Asociación Argentina de la Ciencia del Suelo, 2017)Los objetivos fueron: i) evaluar la cantidad y distribución de raíces de centeno y vicia como cultivos de cobertura (CC) y; ii) cuantificar el aporte de N de raíces en el perfil y su impacto sobre la disponibilidad de ... -
Vetch-rye biculture is a sustainable alternative for enhanced nitrogen availability and low leaching losses in a no-till cover crop system
(2017-12)The reliance of current farming systems on synthetic fertilizers caused concerns about their sustainability, and alternatives to supply nitrogen through biological processes have to be adapted to practical conditions. The ...
