Available Sulfur (mg/kg): Secondary macronutrient that helps form and grow seeds. It also aids in the production of amino acids, proteins, enzymes and vitamins. The data generated by MoA-ATI (EthioSIS Project) using thousands of field-lab data and satellite data (Covariates) as an input in machine learning models.

The Harmonized World Soil Database version 2.0 (HWSD v2.0) is a unique global soil inventory providing information on the morphological, chemical and physical properties of soils at approximately 1 km resolution. Its main objective is to serve as a basis for prospective studies on agro-ecological zoning, food security and climate change. The Harmonized...
