National Biodiesel Day is March 18, and the Iowa Biodiesel Board is suggesting that farmers ask for and use biodiesel as they head into spring planting.

“We’re challenging every farmer in Iowa to request that their fuel distributor offer biodiesel blends this spring,” said Grant Kimberley, IBB executive director and a soybean farmer who uses biodiesel on his farm. “A thriving biodiesel market helps everyone in the ag sector.”

March 18 is National Biodiesel Day because it is the birthday of Rudolf Diesel, the man who invented the engine that bears his name. He ran early models on peanut oil, and was a visionary for renewable fuel.

“I urge farmers to recognize the importance that renewable energy has in a strong and vibrant farming future,” said Ron Heck, an Iowa soybean farmer and IBB officer. “Those of us in the farming community must walk-the-walk by supporting clean energy solutions on the farm.”

Heck noted he has used biodiesel on his own farm for many years. But a poll of more than 360 Iowa farmers conducted this winter by the Iowa Soybean Association finds room for increased biodiesel use. About 41 percent said they use biodiesel in their farming operations. “Not readily available” was the primary reason cited for not using the fuel. However, availability has improved the last several years due to favorable state legislation.

Biodiesel can be used in any diesel engine in blends of up to 20 percent (B20). All of the major Original Equipment Manufacturers producing engines and equipment for the U.S. agricultural market support B20 or higher in their warranty position statements.
