Última Soil structure and greenhouse gas production differences between row and interrow positions under no-tillage Scientia Agricola Silva,Alvaro Pires da; Ball,Bruce C.; Tormena,Cássio Antonio; Giarola,Neyde Fabiola Balarezo; Guimarães,Rachel Muylaert Locks. No-tillage in Brazil is an efficient agricultural system that improves crop productivity whilst controlling erosion caused to the soil by degradation. However, there is some concern regarding soil compaction. Our objective was to determine whether the function of soil structure in sustaining crop growth was dependent on row and interrow positions in long-term no-tillage. We took soil samples from a field in a commercial farm under long-term no-tillage since 1979 on a clayey Oxisol in Southern Brazil. We assessed soil physical quality using the revised Peerlkamp technique and measured bulk density, air-filled porosity and air permeability of intact soil cores. Samples were incubated to assess in vitro N2O and CO2 production. The soil physical and structural...
