Transient poverty among pastoral households in the semi-arid lowland of Baringo District, Kenya
(Ozean PublicationDepartment of Land Resource Management and Agricultural Technology,, 2012)This study was carried out in Baringo District of Kenya to determine poverty among sedentary and semi-nomadic pastoral households. Results indicate that the sedentary agro-pastoralists tend to diversify their sources of ... -
MIRCENS: Catalytic tools in agricultural training and development
(Department of Soil Science, 1986)A global network of Microbiological Resources Centres (MIRCENs) , set up by Unesco, includes five centres concerned with biological nitrogen fixation. These centres are Kenya, Brazil, the United States and Senegal-train ... -
Factors influencing transient poverty among agro-pastoralists in semi-arid areas of Kenya
(African Crop Science SocietyDepartment of Land Resource Management and Agricultural Technology,, 2012)In Africa, many pastoral households are increasingly settling in response to curtailed mobility and shrinking grazing areas. Households in pastoral areas are characterised by few resources, low income, low level of ... -
Population dynamics of soil microorganisms in relation to proximity of termite mounds in Kenya
(Department of Soil Science. University of Nairobi, 1982)Microbial populations estimated in termite-affected soils show that bacteria and actinomycetes are most abundant during the wet season. The highest density of bacteria recorded was 106 and, of actinomycetes, 105g dry soil. ... -
Effect of nitrogen fertilizer on yield of beans inoculated with Rhizobium phiseoli
(Department of Soil Science, University of Nairobi, 1982)There have been reports of legumes responding to application of nitrogen fertilizers and there are suggestions that even where legume seeds are inoculated with effective strains of Rhizobium phaseoli, a nitrogen starter ... -
Groundwater salinlty and depth effects on soil salinlty in a furrow lrirrigated area in Kenya
(2003)The effect of groundwater salinity and depth on soil salinity was investigated in a furrowirrigated area of Kenya dqring consecutive wet and dry seasons. The groundwater salinity was significantly (P < 0.05, R2 = O.75-O.88) ... -
Effects of ripe papaya (Carica papaya) seed powder on the seminiferous epithelium of the boar testis
(Department of Clinical Studies, Faculty of Veterinary Medicine, University of Nairobi, 2012)The effect of oral administration of ripe Carica Papaya seed powder on testicular histology of Sus scrofa domestica boars has been addressed in the present article. Fifteen pubertal Large White boars were randomly selected ... -
Factors Affecting Growth of Bdellovibrio on Rhizobium
(Laboratory of Soil Microbiology, Department of Agronomy, Cornell University Ithaca, New York, 1975)The extent ofdecline in the population density of Rhizobium sp. exposed to Bdellovibno was markedly reduced in the presence of montmorillonite, kaolinite or vermiculite but not by a soil clay fraction. Increasing levels ... -
The Socio-economic and Ecological Impacts of Small-scale Irrigation Schemes on Pastoralists and Drylands in Northern Kenya
(Department of Range Management, University of Nairobi,, 2001)Northern Kenya, as in other sub-Saharan arid and semi-arid regions, has faced challenges related to the prevailing socio-economy, ecology and polity in the last quarter of last century. In some of these areas, pastoralists ... -
Protozoa and the decline of Rhizobiurn populations added to soil
(Laboratory of Soil Microbiology, Department of Agronomy, Cornell University Ithaca, New YorkDepartment of Soil Science. University of Nairobi, 1975)A fall in Rhizobium abundance occurred in nonsterile soil inoculated with large numbers of the root-nodule bacteria but many of the rhizobia still survirved. No such decline was evident in sterile soil. Protozoa feeding ... -
Influence of some soil physical properties on infiltration rate and hydraulic conductivity of 3 salt.affected soils in Kenya
(Department of soil science, 2001)Infiltration rate (IR) is the volume flux of water flowing into the profile per unit of soil surface area (Parr and Bertrand, 1960) when the soil is subjected to a shallow depth of ponding at the surface (Ghildyal and ... -

Direct rapid analysis of trace bioavailable soil macronutrients by chemometrics-assisted energy dispersive X-ray fluorescence and scattering spectrometry
(ElsevierDepartment of physicsDepartment of Land Resource Management and Agricultural Technology,, 2012)Precision agriculture depends on the knowledge and management of soil quality (SQ), which calls for affordable, simple and rapid but accurate analysis of bioavailable soil nutrients. Conventional SQ analysis methods are ... -
Field assessment of the effect of cumulative soil loss on soil productivity
(Department of Soil Sciences, Swedish University of Agricultural SciencesDepartment of Soil Science. University of Nairobi, 2001)Soil erosion affects physical and chemical soil properties by reducing water infiltration rates, soil water holding capacity, soil fertility and Ieading to deterioration of soil structure. Research on the relationship ... -
Hydraulic properties of andosols following deforestation in the northern slopes of Mt. Kenya
(Department of Soil Science, University of Nairobi, 1999)Deterioration in soil hydraulic properties due to deforestation adversely affects the hydrology of catchments, especially those on mountain slopes. The effects of clearing natural forest (NF) for potato cultivation (PC) ... -
Mountain big sagebrush browse decreases dry matter intake, digestibility, and nutritive quality of sheep diets.
(1995-11)A metabolism study evaluated the influence of increasing quantities (0-30% dry matter basis) of mountain big sagebrush (Artemisia tridentata ssp. vaseyana Rydb. Beetle) on dry matter intake and in vivo digestibility of ... -
Soil organic carbon, nitrogen and phosphorus losses in eroded sediments from run-off plots on a clay soil in Kenya
(Depanmentofsoil Science. University of NairobiDepanment of soil sciences, Swedish universiry of Agriculrural sciences, 1998)Poor crop growth in many parts of Kenya may be due to unfavourable soil chemical characteristics brought about by unchecked accelerated soil erosion. However information on the effects of erosion on soil fertility is ... -
Feasibility for chemometric energy dispersive X-ray fluorescence and scattering (EDXRFS) spectroscopy method for rapid soil quality assessment
(Department of Land Resource Management and Agricultural Technology,, 2011)Soil quality assessment (SQA) is important for modulating agricultural productivity and thus requires simple and rapid analysis of soil (macro & micro) nutrients (here called soil quality indicators – SQIs). We report ... -
