Soil and water conservation, and soil fertility management effects on rain water productivity of maize hybrid in Burkina Faso

This article assesses the combined effects of Soil and Water Conservation (SWC) practices and soil fertility management on rain water productivity of maize hybrid. On-farm experiments were carried out in two districts of Burkina Faso. The treatments were built as association of two SWC technologies combined with three fertilization options. It is found that the efficacy of SWC practices decrease with the increase in the mean annual rainfall. »

Gender and inorganic nitrogen: what are the implications of moving towards a more balanced use of nitrogen fertilizer in the tropics?

This article discusses the gender dimensions of moving towards a more balanced use of nitrogen fertilizer. For agriculture to play a role in climate change mitigation strategies to reduce emissions from inorganic nitrogen fertilizer through a more balanced and efficient use are necessary. Such strategies should align with the overarching principle of sustainable intensification. »

Fertilizer use optimization in Sub-Saharan Africa

This book provides a detailed explanation on optimizing fertilizer use within an Integrated Soil Fertility Management Framework in 13 African countries. The book shares the findings of the Optimizing Fertilizer Recommendations in Africa (OFRA) project. The last chapter elaborates on enabling fertilizer use optimization, and how to maximize potential profits of fertilizer use while taking the farmer’s context into account and keeping risks low. At the farm level enabling fertilizer use optimization is in early stages for most countries but considerable experience has been gained from Uganda, as well as Kenya and Tanzania. »

Agronomic biofortification of crops to fight hidden hunger in sub-Saharan Africa

This article in the Global Food Security journal discusses the effectiveness of agronomic biofortification – the application of mineral micronutrient fertilizers to soils or plant leaves to increase micronutrient contents in edible parts of crops – and it’s potential to fight hidden hunger. There is evidence that agronomic biofortification can increase yields and the nutritional quality of staple crops, but there is a lack of direct evidence that this leads to improved human health. »

Fertilizers and low emission development in sub-Saharan Africa

This policy brief by CGIAR argues that an opportunity exists in Africa to meet the future food security needs while using N fertilizers efficiently. Many countries in Africa included fertilizer use, soil fertility management, and agricultural inputs as part of their contributions to the Paris Climate Agreement. »

Soil fertility gradients and production constraints for coffee and banana on volcanic mountain slopes in the east African rift

This article reveals important relations and gradients between soil fertility parameters and its corresponding environment along the slope of the Mt. Elgon in Uganda and Kenya. Mt Elgon is a volcanic mountain and is one of the most productive agricultural regions, dominated by coffee an banana cultivation. »
