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 ... -
Ultra‑Trace Analysis of Fallout Plutonium Isotopes in Soil: Emerging Trends and Future Perspectives
(Chemistry Africa, 2023)The measurement of isotopic abundances and ratio variations of plutonium can provide important information about the sources and behaviours of radiogenic isotopes in the environment. The detection of ultra-trace isotopes ... -
Spatial Prediction and Mapping of Gully Erosion Susceptibility Using Machine Learning Techniques in a Degraded Semi-Arid Region of Kenya
(Land, 2023)This study aimed at (i) developing, evaluating and comparing the performance of support vector machines (SVM), boosted regression trees (BRT), random forest (RF) and logistic regression (LR) models in mapping gully erosion ... -
Effect of land rehabilitation measures on soil organic carbon fractions in semi-arid environment
(Frontiers in Sustainable Food Systems, 2023-02)Soil erosion threatens the sustainable intensification of food systems among smallholder farmers in arid and semi-arid lands (ASALs). Intensifying adoption of soil mitigation and rehabilitation measures is thus needed ... -
Combining measurements, modeling and machine learning to improve N2O accounting for sustainable agricultural development in sub-Saharan Africa
(Swiss Data Science Center, 2023-06)Sub-Saharan Africa continues to grapple with food insecurity due to low crop yields. While an increase in synthetic fertilisers could potentially increase agricultural productivity in the region, it would lead to an ... -
Effect of soil amendments on availability of soil phosphorus and uptake by maize in Vihiga County, western Kenya
(African Journal of Rural Development, 2018)The combined use of organic inputs and fertilizers as promoted via Integrated Soil Fertility Management (ISFM) approach may have a significant effect on bioavailability of phosphorus (P) and enhance its uptake by crops. ... -
Wheat Spikelet Length Response to Phosphate Fertilizers on Acid Soils in Uasin Gishu County, Kenya
(International Journal of Science and Research (IJSR), 2020-11)The study aimed at investigating response of wheat spikelet length, grain yield, grains per spikelet, and soil chemical properties as influenced by liming at 2tha-1 (main plots), P sources NPK (23:23:0), DAP (18:46:0), and ... -
Perception of Farmers’ on Soil Fertility Problems and Replenishment Technologies in the North Rift Region of Kenya
(Asian Journal of Agricultural Extension, Economics & Sociology, 2020-07)This paper investigates the farmers’ perception on soil fertility replenishment technologies in the North Rift Region of Kenya. A survey was conducted in Trans Nzoia and Uasin Gishu counties of the North Rift Region of ... -
Impact of Seasons on Soil Physico-Chemical Properties and Tea Yields Based on Enriched Sheep Manure Used in Kericho, Kenya
(Journal of Agricultural Chemistry and Environment, 2019)Tea (Camellia sinensis (L) O. Kuntze) is a perennial crop grown for beverage consumption. Its production is the leading foreign exchange earner in Kenya contributing about 26% foreign exchange and 4% GDP. Nitrogen (N), ... -
