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
(International Journal of Plant & Soil Science, 2025-07)Introduction:The widespread use of antibiotics in livestock production results in significant excretion of unmetabolized residues in manure, posing risks such as the emergence of antibiotic-resistant bacteria(ARB), ... -
Arbuscular Mycorrhizal Fungi Enhance P Uptake and Use Efficiency of Wheat (Triticum aestivum L.) in Ferralsols: A Study at Uasin Gishu County, Kenya
(Asian Journal of Soil Science and Plant Nutrition, 2025)Deficiency of macro and micronutrients is a major challenge to sustainable wheat production. Integrating biostimulants such as Arbuscular Mycorrhizal Fungi (AMF) and inorganic fertilisers has been shown to enhance wheat ... -
Findings from a survey in Western Kenya to determine the soil fertility replenishment technologies adoption rates
(International Journal of Agronomy and Agricultural Research (IJAAR), 2019)A survey on adoption levels of the existing soil nitrogen replenishing technologies amongst farmers in three counties in western Kenya was carried out in June 2011. Three farmer associations were Angurai Farmers Development ... -
The Role of Sorghum Legume Intercroping System in Improving Soil Productivity on Small Holder Farmers in Western Kenya
(International Journal of Research and Innovation in Social Science (IJRISS), 2022)Declining crops yield in the smallholder farmers cropping systems of sub-Saharan African (SSA) present the need to develop more sustainable production systems. Depletion of essential plant nutrients from the soils have ... -
Improving Soil Fertility and Crops Yields through Organic and inorganic inputs in Smallholder Farmers’ fields in Western Kenya
(International Journal of Research and Innovation in Social Science (IJRISS, 2022)Organic (FYM) and inorganic (Mavuno) manure and their combination were evaluated on sorghum grain yields and some soil chemical characteristics in the 2016 SR and 2017 LR growing seasons FYM, Mavuno and or their ... -
Effects of Source and Rates of Potassium Fertilizer on Yield Traits and Potassium Use Efficiency of Potato in a Kenyan Ferralsol
(Asian Journal of Soil Science and Plant Nutrition, 2023-09)Aims: Potassium (K) is one of the nutrient elements taken up in large amounts by potatoes, yet there is little research output on K fertilization of the crop in Kenya, due to the assumption that its natural soil reserves ... -
