GENERAL KNOWLEDGE

Detailed explanation-1: -Clay soil retains more water because of the presence of small and fine particles. Loamy soils have medium size particles, so it retains moderate amount of water. Sand with low nutritional content and larger particles retain the least amount of water.

Detailed explanation-2: -Clayey soil is composed of very fine mineral particles with high water holding capacity. Due to its good water holding capacity, clayey soil is used for growing crops in fields.

Detailed explanation-3: -Clay soils retain more water and nutrients than sand, but there is little percolation of the water and less oxygen for the plant due to smaller pore sizes than those of coarser textures.

Detailed explanation-4: -Soil textures with high clay content include clay, silty clay, sandy clay, clay loam, silty clay loam and sandy clay loam. Those textures with the word “loam” in their name generally have between 20 to 40% clay, with varying amounts of sand and silt indicated by the names.
