The role of conservation soil management on soil and water protection at different spatial scales [PDF]

, 2006
Agriculture has a direct impact on the soil environment, altering soil properties, surface characteristics and erosion risk. This has led to a move away from conventional tillage to the adoption of conservation practices, aiming to minimise soil ...

Preparation of large sand samples using the air pluviation method – investigation of factors influencing homogeneity [PDF]

EPJ Web of Conferences
Air pluviation is a well-established technique for preparing sand specimens specifically for element and model-scale testing. In this method, dry sand is discharged from a hopper onto a perforated plate, which controls the bulk flow.
