Earthworm communities in native savannas and man-made pastures of the Eastern Plains of Colombia

Autor: Jiménez Jaén, J.J. Moreno, Alonso Decaëns, Thibaud Lavelle, Patrick M. Fisher, Myles J. Thomas, Richard J.

The structure and seasonal changes of earthworm communities were evaluated in a natural savanna and in a improved grass-legume pasture in a Colombian oxisol over a period of 18 months. One plot of 90×90 m was isolated in each of the systems and each month five samples of 1 m2×0.5 m and ten of 20×...

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

Autor: Rao, Idupulapati M. Ayarza, Miguel Angel Thomas, Richard J.

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 (C4), legume alone Pueraria phaseoloides (C3) and grass + l...

Evaluation of some physical properties of an oxisol after conversion of native savanna into legume-based or pure grass pastures

Autor: Gijsman, AJ Thomas, Richard J.

This study evaluated the effects of improved tropical grass and grass–legume pastures on the physical condition of an oxisol, previously covered by native savanna. Two long-term pasture experiments with different grass and legume species and with different stocking rates were used. Measurements w...
