Ion exchange involving calcium-potasium (Ca-K) and calcium-magnesium (Ca-Mg) in soil and organic matter fractions by Cofie, Olufunke O., Pleysier, J.

“…The chemical characteristics of two soil types, an Alfisol and an Ultisol, were studied in the humid tropical zone of southern Nigeria. The objective was to investigate the contribution of soil organic matter (SOM) to nutrient retention characteristics and identify those SOM pools that contribute most to the ion exchange properties of the soils. …”

Use of remote sensing and GIS for improved natural resources management: case study from different agroecological zones of West Africa by Junge, B., Alabi, T., Sonder, Kai, Marcus, S., Abaidoo, Robert C., Chikoye, David, Stahr, Karl

“…Historical and recent aerial photograph and satellite images were analysed to study the change of land use/land cover and soil degradation in different agroecological zones of Nigeria and Benin. The sites were characterized by an expansion of farmland at the expense of forest and shrub, fallow and uncultivated land, at an increasing rate due to population growth, food demand and land scarcity. …”

Economic impacts of soil fertility management research in West Africa by Akinola, Adebayo A., Alene, Arega D., Adeyemo, R., Sanogo, D., Olanrewaju, A.S.

“…This paper assesses the potential economic impacts of balanced nutrient management systemstechnology options: BNMS-manure, which combines inorganic fertilizer and organic manure,and BNMS-rotation, which is maize–soybean rotation, in maize-based systems in the northernGuinea savanna areas of Nigeria, Ghana, Togo and Benin. The economic surplus analysissuggested that BNMS-manure research and extension could achieve returns ranging from 17 to25% and a maximum adoption of 24 to 48%, for the conservative and base scenario respectively;and that BNMS-rotation research and extension could achieve returns ranging from 35 to 43%and a maximum adoption of 20 to 40%, for the conservative and base scenario respectively. …”
