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×...

Adquisición y reciclaje de fósforo en sistemas de cultivos y pasturas en suelos tropicales de baja fertilidad
The effects of different types of land management on the soil macroinvertebrate communities on acid soil savannas of Colombia have been assessed using the Tropical Soil Biology and Fertility Program (TSBF) methodology. Invertebrates were identified among broad taxonomic units, TU (Orders or Famil...

Impact of land management on soil macrofauna in the Eastern plains of Colombia
This was especially due to the presence of a large glossoscolecid anecic species, Martiodrilus carimaguensis Jim\233nez and Moreno, which has been greatly favored by conversion of savanna to pasture. Endogeic species were dominant in the natural savanna whereas the anecic species accounted for th...
