Jiménez Jaén, J.J.Decaëns, ThibaudThomas, Richard J.Lavelle, Patrick M.[Soil macrofauna: an available but little-known natural resources]Soil macrofauna: an available but little-known natural resources

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...


Gijsman, AJThomas, Richard J.[Evaluation of some physical properties of an oxisol after conversion of native savanna into legume-based or pure grass pastures]Evaluation of some physical properties of an oxisol after conversion of native savanna into legume-based or pure grass pastures

It is widely believed that tropical soils (mainly Oxisols) have excellent physical characteristics such as high infiltration rates, high permeability of water, good and stable soil structure and that consequently, they can support mechanized agriculture. However in the Eastern Plains (Llanos Orie...
