Sennhenna, ANjarui, Donald M.G.Maass, Brigitte L.Whitbread, Anthony M.[Can short-season grain legumes contribute to more resilient and productive farming systems in semi-arid Eastern Kenya?]Can short-season grain legumes contribute to more resilient and productive farming systems in semi-arid Eastern Kenya?

Planted fallow systems under slash and mulch management were compared with natural fallow systems at two farms (BM1 and BM2) in the Colombian Andes. The BM1 site was relatively more fertile than the BM2 site. Planted fallow systems evaluated included Calliandra calothyrsus CIAT 20400 (CAL), Ind...

Differences in shoot and root growth responses to varying phosphorus supply and soil type

Low phosphorus (P) supply is a major limitation to pasture establishment and production in highly weathered acid soils. Previous research showed that the forage legume, Arachis pintoi, was more efficient in acquiring P from infertile acid soils than the forage grass, Brachiaria dictyoneura. The m...

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×...
