Soil amendments have been proposed as an effective way to enhance soil carbon stocks on degraded soils, particularly in dryland farming areas. Soil organic carbon (SOC) plays an important role in improving soil quality, and soil aggregates are known to be crucial in sequestering and protecting SOC. However, how aggregation and protection of …

Bentonite increment in the soil increases the plasticity index of the mixtures, thus raising the optimum moisture content. The compaction effects are greatly reduced when more water is added to the sample. The reason for the rise in OMC is that a soil mass with a higher percentage of fine particles needs extra moisture to hydrate its particles.
