Global Soil Nutrient Map (GSNMap)

The GSNmap will allow for the identification of areas presenting soil nutrient depletion and/or excesses associated with less nutritious food crops and potentially harmful losses to the environment. Thus, this timely product will be essential for managing soils in a sustainable and data-driven way to reduce the misuse of fertilizers and assure sufficient, safe and nutritious food for all. For instance, the GSNmap will bridge the gap between soil information and farmer needs by providing the basis for locally relevant soil fertility and fertilizer recommendations to increase the fertilizer use efficiency.

GSNmap products will be developed following a two phase approach:

• Phase I: development of soil nutrient and associated soil property maps;
• Phase II: quantification, analysis, projections of nutrient budgets for agricultural land use systems at national, regional and global scale.

The GSP has been promoting the appropriate use of synthetic and organic fertilizers adapted to soil and crop needs since the adoption of the International Code of Conduct for the Sustainable Use and Management of Fertilizers.

The GSNmap also representes are direct outcome of the recent Global Symposium on Soils for Nutrition (Soils, where food begin, 26-29 July, 2022), specifically to address theme I: Available information and knowledge gaps to undertake monitoring and mapping of soil nutrients are identified. During the symposium the discussions focused on the latest science and policies on soil nutrient management, and the best tools to map and monitor soil nutrients.
