The use of carbon isotope ratios to evaluate legume contribution to soil enhancement in tropical pastures

, : The use of carbon isotope ratios to evaluate legume contribution to soil enhancement in tropical pastures. Plant & Soil 162(2): 177-182

Soil carbon distribution with depth, stable carbon isotope ratios in soil organic matter and their changes as a consequence of the presence of legume were studied in three 12-year-old tropical pastures (grass alone - Brachiaria decumbens (C-4), legume alone - Pueraria phaseoloides (C-3) and grass + legume) on an Oxisol in Colombia. The objective of this study was to determine the changes that occurred in the 13C isotope composition of soil from a grass + legume pasture that was established by cultivation of a native savanna dominated by C-4 vegetation. The 13C natural abundance technique was used to estimate the amount of soil organic carbon originating from the legume. Up to 29% of the organic carbon in soil of the grass + legume pasture was estimated to be derived from legume residues in the top 0-2-cm soil depth, which decreased to 7% at 8-10 cm depth. Improvements in soil fertility resulting from the soil organic carbon originated from legume residues were measured as increased potential rates of nitrogen mineralization and increased yields of rice in a subsequent crop after the grass + legume pasture compared with the grass-only pasture. We conclude that the 13C natural abundance technique may help to predict the improvements in soil quality in terms of fertility resulting from the presence of a forage legume (C-3) in a predominantly C-4 grass pasture.
