A deficiency in sulfur, an essential nutrient for plants, may be limiting crop yields in many regions around the world. A two-year project will compile global data on sulfur for major crop systems around the world — information that is key to inform public and private investments in agriculture. Working with an extensive network of global partners, the team will help countries quantify and address sulfur deficiencies. That progress will help advance crop yields to meet the world’s growing food demand and reduce the negative environmental footprint associated with excessive fertilizer use in some regions. “The current project will use an ensemble of methods to diagnose sulfur deficiencies, including on-farm nutrient balances, soil and plant analyses and sulfur omission trials,” Carciochi said.
