Organic carbon transport under simulated rainfall conditions for different land uses

The demand for information on carbon transport led to the generation of data on the output of organic carbon in soil particles in suspension. Different land uses were considered: buffelgrass pasture (BGP), abandoned farmland (AFL) and native rangeland (NR). The rainfall simulation technique was used to generate runoff on runoff plots (3 x 1 m) in order to obtain in each land use a 0.5-liter aliquot, from which the solid sediments (soil and organic material) were separated and the carbon percentage determined by the Walkley & Black analysis method. A randomized block experimental design with three replications was used to determine differences in carbon content (%). The results show that the highest average values of carbon in suspended sediment were recorded in native rangeland and under initial moisture conditions (3.79 %), whereas the best land cover conditions in the buffelgrass pastures and abandoned farmland plots (1.20 and 1.18 % respectively) had lower carbon losses than those that occurred in the native rangeland (3.11 %).
