pedogenesis is the study of soil
laterite soil undergo leaching.
the organic matter present in the soil which is formed from the dead rains of plants and animals is called humus.
characteristics-
red
1)the soil is red in colour due to the presence of oxides of iron.
2)it is an in-situ soil.
black soil
1)it is an in situ soil
2)the soil is claret in nature

Pedogenesis refers to the process of soil formation.
Various factors like change in temperature, actions of running water,wind , actions of decomposers are responsible for the formation of soil
The laterite soil is formed through leaching due to heavy rainfall.
Humus is found in the topsoil which is formed due to decomposition of dead plants by micro organisms present in soil. Humus content helps in providing nutrients to the soil
Characteristics of black soil ---
1) The soils are made of extremely fine clayey material.
2) They have excellent water holding capacity.
3) The black soil is rich in calcium carbonate, magnesium, potash and lime.
4) During hot weather, the soils develop deep cracks which helps in proper aeration of soil.
5) When wet, the black soil become sticky.
Characteristics of red soil ----
1) Red soil develop on crystalline igneous rocks.
2) The soil develop in areas of low rainfall particularly in eastern and southern regions of Deccan plateau.
3) The color of soil is red due to diffusion of iron in crystalline and metamorphic rocks.
