About Us

Information generation and dissemination is critical for national and regional developments in modern times. The country-wide digital soil mapping undertaken by the Soil Research Institute (SRI) of the Council for Scientific and Industrial Research (CSIR), Ghana holds georeferenced legacy soil profile records of Ghana and data of soil physico-chemical properties, that have been inventorized and compiled from a wide array of data sources including legacy data and detailed field surveys across the length and breadth of the country.  The compilation of the soil information (chemical data, physical data, Soil maps, suitability maps, fertility maps) was done from available regional soil survey or detailed reconnaissance soil survey maps at the scale of 1:250,000. The compiled soil information covers nearly the entire country of Ghana, and serves as base maps, supported by 1:50,000 topographical maps sourced from the Survey and Mapping Department of Ghana.

All records about the compiled soil information include but not limited to soil profile layer attribute data and with soil analytical data (physical and chemical properties of the soils of Ghana). All soil attribute values are standardized according to standard conventions and validated per internationally accepted rules.

Digital soil mapping was done by combining the carefully scrutinized and compiled soil information (devoid of odd values and outliers) with high-resolution gridded environmental covariates using geo-statistical methods. The digital soil maps generated will undoubtedly provide valuable soil information to support smallholder farmers with more and efficient sustainable agricultural practices. The information sourced from the digital maps will help smallholder farmers to optimally allocate resources and agricultural inputs to enhance and expand their production frontiers. The digital soil maps can potentially help advice smallholder farmers and investors in yield forecasting, soil and crop suitability and ideal soil nutrient management (e.g. fertilizer application rates, types, etc.)

The hosted soil information will certainly be a game-changer as it raises hopes for much improved soil health, quality production, and farm profitability. In the long run, it will contribute immensely to increasing food production, enhancing and ensuring food security, reduction in poverty and improvement in the livelihood resilience of smallholder farmers in Ghana. The Project was financially supported by the Modernizing Agriculture in Ghana (MAG) Programme, funded by the Government of Canada.
