(Journal of Aquatic and Terrestrial Ecosystems, 2025-08)This study assessed Pb uptake and distribution in Raphanus raphanistrum (RR) and Brassica napus (BN) grown in agricultural soils from Moiben Sub-County, Kenya, under three soil treatments: Pb-spiked soil (to ≈1000 mg/kg), ... -
Assessing Status of Agroecological Biodiversity in Smallholder farming: Evidence from FAO TAPE Tool Localization in Busia County, Kenya
(Journal of Crops, Livestock and Pests Management, 2025-08)Agroecological biodiversity is the variety and variability of above ground organisms, that is crops, livestock, trees, and activities considered under agricultural systems. This study investigated the extent of above ... -
EFFICIENCY OF ARBUSCULAR MYCORRHIZAL FUNGI IN ENHANCING PHOSPHORUS AND COPPER UTILIZATION IN WHEAT GROWN IN FERRALSOLS OF UASIN GISHU COUNTY, KENYA
(University of Eldoret, 2025)Declining soil fertility characterized by deficiency of both macro and micronutrients is a major challenge to sustainable wheat production. Integrating bio-stimulants such as Arbuscular Mycorrhizal Fungi (AMF) with ... -
Spatial–Temporal Influence of Sand Dams on Chemical and Microbial Properties of Water from Scooping Holes in Degraded Semi-Arid Regions
(Water, 2023-09)Communities in semi-arid lands use sand dams to enhance access water during the dry seasons. However, there is limited information on the quality of water derived from these sand dams, especially in degraded lands where ... -
A Review on Challenges and Opportunities in Management of Soils of Arid and Semi-Arid Regions of Kenya
(East African Journal of Environment and Natural Resources, 2022)Arid and semi-arid lands occupy currently 88% of arable land mass in Kenya, a region with significant diversity of production systems and economic opportunities. However, these areas are characterised by low and erratic ... -
Drivers of Gully Erosion and its Socio- economic and Environmental Effects in a Tropical Semi-arid Environment
(Asian Journal of Soil Science and Plant Nutrition, 2024-03)Gully erosion is a form of severe land degradation, which is more pronounced in semi-arid and arid environments due to their vulnerable ecosystems. Establishing the causes and effects of gully erosion is therefore ... -
Enhancing Sorghum Productivity in Acidic Soils Through Lime– Fertilizer Synergism: Agronomic, Economic, and Composite Performance Analysis
(International Journal of Research and Scientific Innovation (IJRSI), 2025-11)Sorghum productivity in Western Kenya is severely constrained by acidic soils, particularly Ferralsols and Acrisols prone to aluminum toxicity and phosphorus fixation. This study assessed the performance of limeintegrated ... -
Soil-Plant Nutrient Dynamics and Fertilizer Use Efficiency in Maize & Desmodium Cropping System
(International Journal of Environmental and Agriculture Research, 2025-10)Soil fertility decline and inefficient nutrient use remain major challenges limiting maize productivity in the arid and semi-arid lands (ASALs) of Kenya. This study evaluated the effects of integrating farmyard manure ... -
Nutrient dynamics and decomposition of agroforestry litter in acidic soils of Uasin Gishu County, Kenya
(Journal of Soil Science and Environmental Management, 2025-04)Multiple forms of biomass, including litter, herbaceous, and woody biomass emanating from agroforestry systems, have numerous environmental and socioeconomic benefits, including improved soil health, biodiversity, carbon ... -
Response of Rice Beans (Vigna umbellata) to Different Phosphate Fertilizer Rates, Sources and Cropping Systems Established in Western Kenya
(International Journal of Plant & Soil Science, 2025-09)Rice bean despite being an underutilized crop is a multipurpose legume crop with a potential of improving food security in western Kenya. Acidic soils with low phosphate and organic carbon levels limit its production. ... -
Aerobic Composting of Antibioticcontaminated Manure: Degradation Processes and Their Effects on Greenhouse Gas Emissions
