Mark Leitman, director of business development and marketing for the Propane Education & Research Council, talks about the goals of the council and the incentives that have been offered to have farmers switch to propane-powered equipment. Switching from diesel to propane engines for irrigation is a big aspect of the PERC incentive program. PERC reported that farmers who installed propane-powered irrigation engines cut their fuel costs by 56 percent per hour compared with similar diesel-powered engines. The self-reported 2013 results are from 148 farmer-participants in 16 states who installed 214 propane irrigation engines.
