Abstract
Eric and Ann Franzenburg of Pheasant Run Farm near Van Horne constructed three greenhouses on their farm in 2008. In 2009 they took data on crops grown in these greenhouse to determine if heating the soil was cost effective, and to determine if they could gain a longer period of production profitably. Results of this data collection indicate bottom growing over a longer season does make sense for this farm, and season extension is lucrative for their operation. They learned information from recording data over 2009 that will help them tailor their growing plan to maximize profit potential.
