Abstract

Organic matter of a soil amended with composted sludges and affected by simulated processes of soil degradation F.

These effects, normally, are avoided with the organic amendment of the soil surface. To model this process, indices of organic matter content of a forest soil classified as Rendzic Leptosol have been investigated in representative soil samples of Zarra (Valencia, Spain). Under laboratory conditions, soil samples amended with three rates of composted sludges (0, 5 and 10% wlw) were subjected to three energy levels of simulated wate
