Answers


Faith
Ferralisation is the process by which weathered material is removed in solution or in suspension from horizon A of soil to horizon B leading to the formation of red soils in horizon A
Eluviation is a type of leaching in which weathered material are moved in solution from horizon A to horizons B and C
Illuviation is the process by which soil materials which have been leached to horizon B are redeposited to horizon A. This leads to concentration of mineral content at horizon A.
Podzolisation is the process by which horizon A is heavily depleted of all minerals especially the bases making the soil acidic.
Calcification is limited leaching which allows the redeposition of calcium compounds within the same profile.
Ribification is a type of leaching in which soils are desiccated during the dry season and leached during the rainy season.
Salinisation is a process in which soils are leached upward through capillarity.

Eluviation involves movement of weathered materials from horizon A to horizon B and C while illuviation involves redeposition of soil materials to horizon A from horizon B
