Leaching decomposition

Webleaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer. This transport results in a porous and open top layer and a dense, compact lower layer. The rate of leaching increases with the … WebEven though AMF have no known saprotrophic capability and cannot directly break down organic nutrients (Herman et al., 2012; Smith & Read, 2008), past studies have reported that AMF can enhance decomposition of organic matter (OM; …
