Effect Of Bacillus Spp. On Root Knot Nematode Population And Galling In Beans
(University of Nairobi, 2000)
Assessing The Ability Of Two Soil Types In The Removal And Retention Of N And P Nutrients From Fish Pond Effluents.
(University of Nairobi, 2004)
Effectiveness of two soil types found at Sagana, Kenya, black clay soil (eutric Vertisol) and a red clay soil (chromic Cambisol), in retaining nutrients from pond effluent was investigated. A laboratory experiment was ...
Evaluation of phosphorus uptake from Minjingu Phosphate rock, growth and nodulation of agroforestry tree species in an acid soil from Kenya. In: Assessment of soil phosphorus status and management of phosphatic fertilizer
(University of Nairobi, 2002)
Most acid soils of the tropics and subtropics show a widespread phosphorus (P) deficiency and high P sorption capacity, and therefore require substantial P inputs for optimum plant growth and production of food and fiber. ...
Available technologies to replenish soil fertility in East Africa
(University of Nairobi, 2007)
Low inherent soil fertility in the highly weathered and leached soils largely accounts for low and unsustained crop yields in most African countries. But in particular, the major nutrients, nitrogen (N) and phosphorus (P), ...
Agricultural intensification, soil biodiversity and ecosystem function in the tropics: the role of nitrogen-fixing bacteria
(University of Nairobi, 1997-08)
Among the nitrogen (N2)-fixing bacteria, the rhizobia in symbiosis with legumes are generally the most important in agriculture, although Frankia, cyanobacteria and heterotrophic free-living N2 -fixers may fix significant ...
Growth response of Grevillea robusta A. Cunn. seedlings to phosphorus fertilization in acid soils from Kenya
(University of Nairobi,, 1999)
Three experiments were conducted to assess the response of
G. robusta
to phosphorus fertilization using acid soils showing
low P
levels from Eastern (Gituamba-Andosols) and
W
estern (Kakamega-Acrisols) Kenya. In the ...
Indigenous populations of rhizobia, legume response to inoculation and farmer awareness of inoculants in East and Southern Africa
(1997)
The Rhizobium Ecology Network of East and Southern Africa (RENEASA) is a participatory research affiliation of microbiologists and agronomists which seeks to better understand biological nitrogen fixation (BNF) and promote ...
