ABSTRACT
The objective of this research was to study the effect of rabbit manure vermicompost (VC) use onto the different organic carbon fraction (C) considering time and soil depth, in order to analyze the organic amendment potential as a C source and the degraded soil capacity for its retention. The VC was place onto the degraded soil as a pile. Chemical and physicochemical determination was carried out at different times after the application, onto VC and soil, at two depths. The VC application increased the Cox, WSC (Water soluble carbon) and TN (Total Nitrogen) content. Carbon and their different fractions were retained, mainly, in the first 5 cm. The use of this kind of organic amendments, applied as a pile on the soil, is an important strategy for the C sequestration (enrichment) on degraded soils.
