Soil loosening persistence with paratill
In Argentina, no-tillage is the main management system where the absence of soil disturbance and the traffic of heavy machine has increased the problems of soil compaction. In order to reverse this phenomenon,decompaction is used, with contradictory results on the duration of the effect of soil loosing. The study wasperformed using a lateral angled decompactor (Paratill) in a Thapto Argic Hapludol. After two years, penetration resistance, bulk density, infiltration and dry matter production was evaluated under two treatments: decompacted; and control (without decompaction). No differences were found in bulk density or infiltration between treatments.Along the studied soil profile, the control treatment showed higher values of penetration resistance in comparison with the decompacted only between 7 and 30 cm, even below the maximum depth reached. Dry matter was higher under decompaction treatment, showing that the effect of decompaction was maintained two years after its application. In conclusion, the effect of decompaction is still evident after two years, improving the penetration resistance parameter and crop biomass production.

En la Argentina predomina como sistema productivo la siembra directa donde la ausencia de remoción y eltránsito de máquinas cada vez más pesadas han incrementado los problemas de compactación. Para revertireste fenómeno se utilizan descompactadores. Existen datos dispares de cuán prolongada es la duración delefecto de descompactación. Se realizó un ensayo utilizando un descompactador angulado lateral (Paratill) en un suelo Hapludol Thapto Árgico. A los dos años se evaluó la resistencia a la penetración, la densidad aparente, la infiltración y la producción de materia seca comparando el tratamiento descompactado con el testigo (sin descompactar). No se encontraron diferencias en densidad aparente ni en infiltración entre ambos tratamientos.Hubo diferencias en la resistencia a la penetración donde el tratamiento testigo alcanzó valores mayores aldescompactado en parte del perfil trabajado y aún debajo de la profundidad máxima alcanzada. La materia seca producida en el tratamiento descompactado duplicó a la del testigo evidenciando que el efecto de ladescompactación se mantiene dos años después de realizada. Se concluye que el efecto de la descompactación se evidencia aún dos años después de efectuada en el parámetro resistencia a la penetración y que el cultivo percibe estos efectos.
