Effects of Residue Management and No-Till on Soil Quality. Soil Quality-Agronomy Technical Note No. 3

摘要

Compared to water or air quality, soil quality is a relatively new concept and relies on indicators, like organic matter, bulk density, nutrient status, and microbial biomass for measuring. Of this, organic matter is probably the most vital in maintaining a quality soil resource. It improves aggregate stability and soil structure, reduces erosion potential, provides energy for microorganisms, is important to nutrient cycling, and improves infiltration, water holding capacity, cation exchange capacity, and the breakdown of pesticides.
