Diagnosing and Mapping the Need for Soil Improvement in Brazil

Brazil has lacked the data for creating a soil fertility survey that could be used for assessing if any nutritional factors are limiting crop yields in the region. The IPNI Brazil Program partnered with the Agronomic Institute of Campinas and São Paulo State University to collect and produce a soil fertility survey, starting with the state of São Paulo. The survey revealed that soil samples analyzed in São Paulo are classified between “very low” and “medium” for phosphorus.
