Impacts of Different Tillage Practices on Soil Water Infiltration for Sustainable Agriculture

Over the years, cultivation using sustainable tillage practices has gained significant importance, but impact of on soil water infiltration is still a concern for landowners due to possible effects crop yield. This study investigates different managements rate sandy clay loam under semiarid environment. Field experiments were conducted in Chott Mariem Sousse, Tunisia. The consisted three treatments, including tine cultivator (TC, 16 cm), moldboard plows (MP, 36 cm) and no-tillage (NT). Three models, Kostiakov, Philip Horton, applied adjust observed data evaluate characteristics studied soils. Comparison criteria, coefficient determination (R2), along with root mean square error (RMSE) absolute (MAE), used investigate best-fit model. results showed that plowing enhanced capacity relative treatments. saturated hydraulic conductivity was highest MP, while it lowest NT, 33.4% 34.1% reduction compared TC respectively. Based obtained results, Philip’s model better higher R2 (0.981, 0.973 0.967), lower RMSE (3.36, 9.04 9.21) MAE (1.46, 3.53 3.72) recorded, respectively, MP TC. Horton’s had low regression between predicted values. It suggested two-term can adequately describe process area.
