Crop Residue and Soil Physical Properties

2018-6-3 · Bulk Density: Bulk density is an important soil property because it affects soil porosity, which in turn affects water infiltration. Systems that produce and return more crop residue to the soil surface should reduce its bulk density because under no-till conditions the residue accumulates in the surface soil. This accumulation should do three

2015-12-25 · Slide 1. Slide 2. Density is defined as the mass in a unit of volume. Slide 3. In the SI unit system, mass is measured in kg and volume is measured in m 3, thus, the unit of density is kg/m 3 (kilogram per cubic meter). But this is inconvenient for most substances, therefore, g/cm 3 (gram per cubic centimeter) is a more common unit of density.
