| Summary: | Soil compaction induced by agricultural machinery is widely recognized as a significant challenge in agricultural fields. This study evaluated soil compaction in six no-till vertisol and calcimagnesic field crops at the Chaouia region. The evaluated fields present different organic matter contents varying from 1% to 3% and notill adoption historic varying from 3 to 15 years. Bulk density ranged from 1.30 g/cm3 to 1.80 g/cm3 according to compaction and the limestone presence. The gradient of limestone (From 3% to 13%) amplified compaction of calcimagnesic soil as the impact of plasticity on compacting vertisol according to influence of soil moisture and timing of machines traffic. Soil strength measurement showed increased compaction from 4.5 MPa to 16 MPa in the vertisol and the calcimagnesic. Soil compactness was related to the limestone gradient according to the spatial correlation found between the soil strength and limestone levels (R2 of 90%). Results showed that compaction was important in the field extremities due to intensive machines/tools traffic and to timing of cropping interventions without respect of the soil plasticity state. The soil strength (as measured value) was correlated to precompression stress (as estimated values) to show the importance of using pedotransfer function as a significant method to evaluate indirectly compactness or susceptibility to compaction of the soil. |
