Leaching affects soil by it removes some minerals on horizon A and moves it down to horizon B.
E Horizon
Horizon B
Refers to the downward movement or loss of dissolved or suspended material within soil by leaching (i.e. salts, nutrients and silicate clays. elluviation leaves the topsoil or A horizon and creates the E horizon. Materials accumulate in the zone of illuviation or accumulation in the B horizon underneath the E horizon.
In soil, water seeps through the A horizon and reacts with humus and carbon dioxide to form acid .

The main difference between rendzina and podsol is B horizon. There is no B horizon in rendzina podsol which is termed as illuvial zone where leaching is most effective. Brown earth soil usually occurs when soil pore space are filled with air. This depends on rainfall , in podsol rainfall is usually higher and so water moves downwards filling the pores with water. Rendzina horizon has more air spaces and so the color is usually brown.
E horizons, or Zone of Eluviation, is one of the layers of soil. It is the layer that is below the topsoil, or A Horizon, and subsoil, or B Horizon. It is the leaching layer, and materials that are dissolved or suspended in water in the soil move down or sideways as the rainwater moves through it through a process called eluviation. It is made up mostly of sand and silt because most of its minerals and clay have been lost as water drips through.
