This paper reports on studies of Faidherbia albida trees and their effects on some properties of vertisols in the Ethiopian highlands. The study was carried at the experiment station of ILCA at Debre Zeit with 850 mm rainfall and at an altitude of 1850 m. Studies on the lateral and vertical influ...

Field experiments were conducted to study the effects of inoculation and application of P on the productivity of Desmodium intortum on an Ultisol and Sesbania sesban on a Vertisol, Alfisol and Ultisol in the Ethiopian highlands. On the Vetisol, the effect of drainage by using broad-bed-and-furrow...

Phosphorus deficiency is the major soil fertility problem limiting forage production in many parts of Africa. The objective of this study was to screen African Trifolium species for dry matter production, nutrient use efficiency and nitrogen fixation potential at different rates of applied Twenty...

Summarizes and discusses the results of an experiment carried out in 1983 with oats and Italian ryegrass on a soil with vertic properties near Debre Berhan area (Ethiopia) to examine the effects of improved drainage and fertilization (N/P).

Most soils in sub-Saharan Africa are P deficient, but the high cost of water-soluble P fertilizers limits the use of P fertilizers by resource-poor farmers. A low-cost alternative is to apply phosphate rocks. We evaluated the effectiveness of unacidulated (PR), 25 percent partially acidulated (PA...

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...
