SOILS, SOIL CHARACTERISTICS AND SOIL MANAGEMENT
www.agronomy.k-state.eduSoils vary in their chemical, physical and biological characteristics. Because of these inherent differences in characteristics, soils have different use capabilities. They respond differently to various cropping, tillage, fertility, and irrigation practices. Soil scientists use the inherent characteristics of soils to give them
