Organic amendments as strategy to increase organic matter in particle-size fractions of a semi-arid soil
The distribution of organic matter (OM) in soil particle-size fractions is a key process in the dynamic and persistence of soil organic carbon. In order to study the distribution of organic amendments among the different soil particle-size fractions in a semi-arid, degraded soil (a sandy loam Haplic Regosol), a 9-month-incubation experiment was carried out after the application of composted organi
