Abstract:
In 2C01 network experiments addressing several research themes were carried out alcng a bio-climatic gradient at several benchmark locations in East, West and Southern Africa using commonly developed research protbcols. The long-term on-stEtion ir als from which originated the technologies tested on-farm continued to run wit the ,Dbjective of identifying sustainability indicators. Soil samples from the long-term tria s were collected for measurement of these parameters using protocols provided by TSBF. Some of the indicators include microbial biomass, organic carbon and tract onation of soil organic matter. In addition, on-farm researchers and farmers' evaluatixls of soil fertility technologies were carried out at different sites. While po Aiig resources, this approach provides opportunities for wider use of the network research output, both to scientists and to farmer clients who are the end-users of the technologie
