AFREC Research Projects

A Farmer-led Program to Advance Soil Fertility Research, Technology Development and Education 

Minnesota's Ag Fertilizer Research and Education Council (AFREC) provides grants for research, education, and technology transfer projects related to agricultural fertilizer, soil amendments and plant amendments.Farm property with a barn, tractor and grain storage facility AFREC began funding research and education in 2008. Current funding for the AFREC program is provided by fertilizer tonnage fees. This program acquires funds through a $0.70 per ton fertilizer tonnage fee on all commercial agricultural fertilizer sold in Minnesota. AFREC is responsible for how all funds are spent. The Minnesota Department of Agriculture provides administrative support for the program.
