Ag Engineering/Agronomy, Central Iowa and BioCentury Research Farms
The goal of the Landscape Biomass Project is to develop a portfolio of biomass cropping systems that together are productive, profitable, and mitigate the negative effects of annual crops on soil and water quality. To accomplish this goal, we have developed several alternative biomass cropping systems and compared them with a conventional continuous corn system. Alternative cropping systems were chosen because of their potential to provide superior biomass yields (triticale/sorghum); some biomass yield while mitigating some negative environmental impacts (corn-soy-triticale/soy and corn-switchgrass); or some short-term biomass yield and superior long-term yield while strongly mitigating negative environmental impacts (triticale/aspen). As crop performance is strongly tied to site factors, we are evaluating these bio-mass cropping systems across a series of landscape positions.
