Introduction Grain size in soil

range of particle siz The grain size of soil particles and their aggregate structures affect the ability of a soil to transport and retain water, air, and nutrients Grain size is classified as clay if the particle diameter is <0002 mm, as silt if it is between 0002 mm and 006 mm, or as sand if it is...
