Sandy soil lacks humus content. Due to the presence of larger size particles, soil has more air spaces. It is highly porous, and water retention capacity is less. It is mostly found in desert areas. Thus, it supports the growth of plants like cactus. Clayey soil has fine particles with smaller air spaces. Hence, it has good water holding capacity. It contains some humus. This soil is the best for the growth of wheat and paddy crops. Loamy soil has humus content and is suitable for crops like lentils. It does not show waterlogging. Black soil contains dead and decaying organic matter and water. Thus, it is suitable for the growth of crops like cotton and sugarcane. Red soil is poor in humus content but becomes quite fertile when manures or fertilizers are added to it. It is suitable for the growth of groundnuts, rice, potato etc. Column A Column B Column C 1.
