Short-term effects of cover crop inclusion under no-tillage management on soil physical quality = Efectos de corto plazo de la inclusión de un cultivo de cobertura bajo siembra dir... por Villarreal, Rafael, Lozano, Luis Alberto, Melani, Esteban, Polich, Nicolás Guillermo, Salazar, María Paz, Bellora, Guido Lautaro, Soracco, Carlos Germán

“…Integrating cover crops (CC) in the crop sequence could lead to an enhancement of the notillage (NT) performance improving soil physical quality (SPQ). The objectives of this work were: i- to determine the SPQ on different moments of the crop cycle during the first year after incorporation of cover cropping (barley and vetch) (CC), as compared with bare fallow (BF); and ii- to measure the impact of cover crops on the top soil water content during the first year of its introduction. …”
