Topic 6: Properties of Soil
www.soil-net.comsilt, clay and organic matter in a particular soil play a large part in the way that it behaves, how it can be man-aged and what it can be used to grow. Sandy soils are easy to cultivate but tend to hold little water and may be droughty, whereas clay soils are more difficult to culti-vate, hold a lot of water and can become waterlogged,

Soils – Fundamental Concepts
web.extension.illinois.eduwater. Soils which have all of their pore space filled with water for several days after a rain are considered in many of the definitions of wet soils within NRCS programs. Except for gravel and rocks that occur occasionally in soils, there are three fractions, sand, silt, and clay.
Soils and Climate
www.soils.orgSoils that are more developed have more horizons and deeper horizons than soils that are less developed. Wet conditions favor leaching, or moving deeper with water, of clay and other minerals so that E and B horizons develop. Warm conditions promote the chemical and biological reactions that develop parent material into soil.
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
