Although the majority of soils in Africa are P deficient, the high cost of conventional water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effect of Egyptian rockphosphate (ERP) from two sources, applied at 50 kg P ha-1, on annual...

Poor drainage of Vertisols and nitrogen (N) and phosphorus (P) deficiencies are some if the major constraints to food and feed production in the Ethiopian highlands. The effects of soil drainage and P supply on N fixation by annual trifolium species and their residual value to succeeding crops wa...

Monitoring and research activities may hinder rather than improve conservation in tropical countries. Those concerned with conservation - particularly academics and aid agencies - too often overlook the practical realities of achieving conservation in the tropics. As a result, many initiatives di...

Tropical conservationists can benefit from understanding human thought processes. We are often less rational than we might believe. Our judgmental biases may sometimes encourage us to overlook or act against major conservation opportunities. Better appreciation of the tricks of the human mind mig...

Sex of calf and year of birth significantly affected birth weight and post-weaning growth. Pre-weaning weights, and pre-and post-weaning growth were significantly affected by season of calving. Cow fertility had a significant influence on weaning, 12- and 18-month weights. Although male calves we...
The effect of urea-molasses feed-supplement blocks (MUB) on feed utilisation and the inclusion of anthelmintic medication into the blocks at strategic times to control nematode parasites was studied in lambs grazed on low quality tropical pasture. 120 Menz ram lambs of 5-7 months of age were divi...
