Northern Iowa farmers will soon be able to invest in a new fuel-making factory. After the start-up of a 45-million-gallon per year ethanol plant in rural Lakota, Midwest Grain Processors plans to offer six-million shares of stock to eligible farmers during March. M-G-P officials say informational meetings will be held Tuesday and Wednesday in Algona, Lakota, Estherville, Mason City, Riceville and Lake Mills.
