Question

What is difference between silt clay and sand

Answer 1

Clay has super fine particles that cling together and prohibit water and nutrient movement, while sand has course particles which allow water and nutrients to leach too rapidly. There actually is one more classification called silt which has particles sizedbetween clay and sand

Answer 2

Clay is the tiniest soil particle.
Compared to sand particles, which are generally round, clay particles are thin, flat and covered with tiny plates.
Clay particles tend to stick together and make very little movement through soil.
sand is a granular material composed of finely divided rockand mineral particles.
It is defined by size, being finer than gravel and coarser than silt.
