Quantifying soil macrofauna in a Colombian watershed
From April to September 1994, macrofauna density, total biomass, and species diversity of earthworms were measured across a range of land use types in the Cabuyal River watershed. The methodology recommended by the Tropical Soil Biology and Fertility (TSBF) Program was used. Macrofauna density, biomass, and diversity of earthworm species varied considerably across land use types, and depths. Initial factor analysis yielded three factors that accounted for 71.8% of the total variance in macrofauna density.

Proyecto Frijol Zona Andina: Antropologia: Informe final
Anthropological work carried out by the PROFRIZA project in Cusco over 2 cropping seasons, between 1988-90, are reported. The status of bean cultivation in the region was assessed, as well as the experience acquired in seed production, small farmer management of farming activities, and the integration of farming communities that have old ways of exchanging products and services. Appropriate technology to promote crop improvement was identified, and crop management aimed at achieving good results on just one field, instead of several fields, and perhaps with low yields.
