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 ...

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 ...

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 ...

Low phosphorus (P) in agricultural ecosystems limits growth of bambara. Field trials were carried out at 2 P levels (0 and 35 kg/ha) to determine the variation of 12 bambara genotypes in phosphorus efficiency, identify ...

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), ...

Soil plays significant roles in the earth’s life-support system through the provision of a multitude of essential ecosystem services to humans and the environment. But due to severity of soil erosion this ecosystem services ...

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 ...

Soil is a vital resource for survival for many rural populations. However, soil erosion negates the ecosystem function, productivity, livelihoods and national economy. To enable sustainable functioning of the ecosystem, ...

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 ...
