Michigan State University and 海角破解版propose practical approach to address soil health crisis in Sub-Saharan Africa
, a researcher from (MSU), in collaboration with Egerton University, is proposing a practical approach to address the soil health crisis affecting densely populated areas of Sub-Saharan Africa (SSA). The region's traditional agricultural practices are becoming unsustainable due to rising population density, leading to low and stagnant yields. The proposed sustainable form of intensification aims to provide recommendations across varying household-specific conditions

The researcher, who has spent eight trips across Western Africa, understands the need for small-holder farmers to improve their farm productivity. Building trust through transparency with the farmers and working closely with the agricultural extension service is vital to gain their respect and adopt recommendations stemming from research.
The research is part of the Sustainable Agricultural Intensification and Rural Economic Transformation (SAIRET) initiative, supported by the Alliance for African Partnerships and the African Development Bank. The group, including Michigan State University, Egerton University, other multiple African universities, and international agencies, is working to promote sustainable agricultural intensification and resilience in Africa. With connections to international and high-level policy makers across Africa, the results of the proposed project will be disseminated to key to important stakeholders.
The project will strengthen ties between MSU and Egerton University. With funding from the Gates Foundation, the group is preparing technical materials for the next Africa Fertilizer Summit, and this project's results will further leverage the group's connections.
The research project, which is being conducted in collaboration with Egerton University's Professor Nancy Mungai of the department of Crops, Horticulture and Soils, Egerton University, will focus on three counties in Western Kenya: Uasin Gishu, Kakamega, and Trans Nzoia. The counties, which are among the leading maize producers in the country, are hilly in topography, with altitudes ranging mainly from 1200 meters to 2500 meters, with annual rainfall of 1000-2000 mm.
The research will involve resampling the same households (sampled in 2014) and conducting soil tests in the same farm fields to test for soil quality trends through time. The survey at each household will include comprehensive soil testing on the largest maize plot of the 350 sampled farmers; estimates of yields based on measuring their fields and obtaining the farmer鈥檚 estimate of the plot鈥檚 production; detailed questions about farmer鈥檚 soil management practices, both those they use and those they don鈥檛 but view as optimal; and question about available organic matter resources.
Soil samples will initially be air dried and stored prior to analyses, which will be completed in Kenya. The research will measure a suite of soil health metrics including SOM, water stable aggregates, bulk density, permanganate oxidizable C (POXC), and soil texture. The research project aims to provide recommendations across varying location- and household-specific conditions. It is hoped that the practical approach will help address soil health issues and provide a platform for sustainable forms of agricultural intensification.
The proposed project is a promising approach to address the soil health crisis in Sub-Saharan Africa, and it will undoubtedly bring significant benefits to the region's small-holder farmers.
