Soil Microbiome

Soil health and bioproducts for improved nutrient-use efficiency and ecosystem services

The vulnerability of intensive and large-scale agricultural production systems in Brazil and the U.S. has increased due to their low crop diversity and heavy dependence on external fertilizers inputs. The U.S. is a significant producer of nitrogen and phosphorus fertilizers but imports large quantities of potassium-based fertilizers. More than 80% of the fertilizers used in Brazil are imported, evidencing a high level of external dependence on a market dominated by few suppliers. Both countries must find alternatives to reduce fertilizer inputs and improve nutrient use efficiency. Microorganisms are an essential strategy to overcome these problems. They promote plant nutrient acquisition and maintain healthy soil, positively benefiting crop growth and yield. Continuous research is necessary to guarantee the success of bioproducts under different environmental conditions. This project aims to advance soil health assessments in the U.S. and Brazil and develop better fertilizer-use efficiency strategies based on bioproducts.
