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...

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...

The dry matter yields of 22 accessions of 7 native annual Trifolium species from the Ethiopian highlands were evaluated for hay production at Shola near Addis Ababa, Ethiopia (altitude 2380 m and latitude 9°02' N). DM yields obtained at a fertiliser rate of 40 kg ha-1 ranged from 1473 kg ha-1 for...

Predictions of tree size and density from a remote sensing model were used together with allometric regression equations from the literature to estimate foliage and above-ground woody biomass in sparse woodlands. Study sites with woody cover ranging from 10-50 per cent were located in the Sudania...

En el Ecoparque Cerro de la Bandera, zona dedicada muchos años a la explotación carbonífera, se evaluó el efecto de dicha práctica sobre propiedades fisicoquímicas y flora microbiana de sus suelos. En tres zonas, bosque nativo (BP); zona intervenida en proceso de regeneración (BS); Zona erosionad...
