Detailed explanation-1: -Sandy soils have large pore spaces and increase water drainage, but do not provide soils with many nutrients. Clay-rich soils, on the other hand, increase water holding capacity and provide many plant essential nutrients.
Detailed explanation-2: -The favourable soil for farming is loamy soil. It has an equal amount of clay, sand, and silt. They are highly productive for the growth of crops.
Detailed explanation-3: -Soils supply the essential nutrients, water, oxygen and root support that our food-producing plants need to grow and flourish. They also serve as a buffer to protect delicate plant roots from drastic fluctuations in temperature.
Detailed explanation-4: -Plants contribute to chemical weathering through root exudates. Soils can be enriched by deposition of sediments on floodplains and alluvial fans, and by wind-borne deposits. Soil mixing (pedoturbation) is often an important factor in soil formation.
