Leaching soil

The materials lost are transported downward (eluviated) and in a lower layer are normally redeposited (illuviated). This transportation results in a thick, compact lower layer and a brittle and free top layer. The leaching risk for a nutrient increases with its mobility in the soil. Among nutrient anions, nitrate is particularly easily leached because it shows negligible interaction with the negatively charged matrix of most Soil acidification is a natural consequence of chemical mineral weathering promoted by soil respiration and leaching in humid climates.

Soil leaching refers is the movement of nutrient elements from topsoil through the soil profile. Leaching causes significant nutrient losses, particularly in humid regions with high precipitation. Leaching is a natural process caused mainly by precipitation, acidification and nitrogen saturation.
