Mutuo, P.Desta, L.Winowiecki, Leigh A.Kihara, JobMango, N.[Catalogue of tested crop, soil, and water management options in target areas of Tanzania, Malawi, and Zambia]Catalogue of tested crop, soil, and water management options in target areas of Tanzania, Malawi, and Zambia

Although soil degradation is a major threat to food security and carbon sequestration, our knowledge of the spatial extent of the problem and its drivers is very limited in Southern Africa. Therefore, this study aimed to quantify the risk of soil structural degradation and determine the variation...


Tamene, LulsegedSileshi, Gudeta W.Ndengu, GiftMponela, PowellKihara, JobSila, AndrewTondoh, Jérôme E.[Soil structural degradation and nutrient limitations across land use categories and climatic zones in Southern Africa]Soil structural degradation and nutrient limitations across land use categories and climatic zones in Southern Africa

Improving soil health by utilizing the appropriate tillage, cropping systems and soil management practices is important for enhanced soil quality and agricultural productivity. Of key importance is effect of these factors on the persistence of soil faunal diversity, biomass and their performance ...

This is a comprehensive dataset specifically on crop response to fertilizers and is obtained from published journal articles, thesis and proceedings spanning at least 5 decades. It represents all the agriculturally productive regions of Ethiopia. The data contains information on region, crop type...

The application of nitrogen in a soil under agricultural production is subject to several pathways including de-nitrification, leaching and recovery by an annual crop. This is as well greatly influenced by the management practices, nitrogen source and soil conditions. The main objective of this s...

Secondary and micronutrients are important in enhancing crop productivity; yet, they are hardly studied in sub-Sahara Africa. In this region, the main focus has been on macronutrients but there is emerging though scattered evidence of crop productivity limitations by the secondary and micronutrie...


Kihara, JobSileshi, Gudeta W.Nziguheba, GeneroseZingore, ShamieSommer, Rolf[Replication Data for: Application of secondary nutrients and micronutrients increases crop yields in sub-Saharan Africa]Replication Data for: Application of secondary nutrients and micronutrients increases crop yields in sub-Saharan Africa

Crop production in sub-Sahara Africa is constrained by low soil phosphorus (P) content. A study was conducted in western Kenya to explore alternative P inputs and ways of optimizing their effectiveness and profitability. A field experiment established in 2007 studied the effects of Minjingu phosp...

André[Long-term effects of TSP and Minjingu phosphate rock applications on yield response of maize and soybean in a humid tropical maize–legume cropping system]Long-term effects of TSP and Minjingu phosphate rock applications on yield response of maize and soybean in a humid tropical maize–legume cropping system

Concentrations and identity of ions in the soil solution may affect soil phosphorus (P) reactions and P availability. In this study, the magnitude of these reactions was evaluated following the application of Minjingu phosphate rock (MPR) combined with chloride and carbonate salts of Na and Ca wi...
