This University of Florida website educates the public about soil texture, which is the distribution of sizes of mineral particles found in soils. After learning the basics about soil separates, students and educators can learn about the USDA textural triangle and the characteristics of the twelve textural classes. Researchers can discover how to determine the correct soil texture in the field. The website addresses the important role soil textures play in the determination of proper land use activities and management practices. Visitors will also find a short discussion about other factors that affect the behavior and qualities of soils. [RME]
