No Tillage Improved Soil Pore Space Indices under Cover Crop and Crop Rotation

The inclusion of a cover crop in a cropping system is a source of organic matter from biomass produced, which enhances biological activities and subsequently improves soil quality. However, the literature also contains the evidence of no changes in soil structural properties due to addition of cover crops. The soil pore system is a primary structural component controlling the air and water exchange in soil, and which is dominated by pore size abundance, tortuosity, and continuity. Gas movement in soil is a phenomenon that occurs mainly by diffusion. Pore space indices include both gas diffusion and tortuosity properties of pore spaces. the objective of the current study was to explore the effectiveness of a combination of tillage system, cover crop and crop rotation on selected soil physical properties a silt loam soil.
