In February 2019, IFCA surveyed its retail members about fertilizer application practices based on the 4R Code of Practice. This survey captured fall fertilizer application practices for 2018, including the percentage of acres treated with 4R practices. Going forward, IFCA will survey its members every winter and summer to capture fall and spring fertilizer-application practices. The 4R metric survey results can be combined with results from the survey conducted by NASS to get a better understanding of the adoption of voluntary practices over time to reduce nutrient losses.
