Effect of soil properties on prediction of soil moisture retention characteristics in acid soils of Meghalaya.

摘要

Study was conducted to evaluate the effect of basic soil properties like mechanical composition, bulk density, CEC and organic carbon content of the soil on water retention characteristics in hilly ecosystem of Meghalaya based on statistical regression model. The predicted soil moisture characteristics from regression model were in good agreement with that obtained from laboratory measurement. Study revealed that mechanical composition i. e. sand, silt and clay contents played a significant role followed by soil organic carbon for soil moisture retention at different potentials and available water characteristics.
