Soil health is improved by disturbing the soil less, growing the greatest diversity of crops (in rotation and as diverse mixtures of cover crops), maintaining living roots in the soil as much as possible (with crops and cover crops), and keeping the soil covered with residue at all times. This handout produced by USDA Natural Resources Conservation Service summarizes why soil health is important and how to make improvements on your farm.
