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 ...
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 ...
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 ...
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 ...
