Soil nutrient constraints coupled with erratic rainfall have led to poor crop yields and occasionally to crop failure in sole cropping in the Guinea savanna of West Africa. We explored different maize-grain legume diversification and intensification options that can contribute to mitigating risks...

Land degradation is a severe problem in the Ethiopian highlands. Factors that may be important in influencing land management and its impacts on resources and human welfare include low and uncertain rainfall in much of the highlands, limited market access and market development, land tenure insec...

The study aimed at identifying soil fertility management practices that promote the Collembola population, diversity and survival in the soil. Soil samples were randomly collected from on farm plots amended with: 1-Mavuno ((Ma)-is a compound fertilizer containing 26% Potassium, 10% Nitrogen, 10% ...

On-station and on-farm studies were carried out in 2008 during the long rains (March – May), in Taita region, Kenya, to assess the effect of various soil fertility regimens on bean stem maggot (BSM) (Ophiomyia spp.) and black bean aphid (BBA) (Aphis fabae) incidences. These studies aimed at gathe...

In African smallholder agriculture, improved farm-scale understanding of the interaction between the household, crops, soils and livestock is required to develop appropriate strategies for improving productivity. A combination of models was used to analyse land use and labour allocation strategie...

We detail the impact of abandoned traditional settlements (or bomas) on plant and nutrient succession in the Amboseli ecosystem, southern Kenya, over the course of a century. Plant and soil data were sampled on and around abandoned settlements. The term, ‘onsite’, refers to the area within the pe...
