Ag Engineering/Agronomy, Central Iowa and BioCentury Research Farms
Grass filter strips established between cropped fields and streams have many potential conservation benefits, including trapping sediments and runoff, providing wildlife habitat, transforming nitrogen in runoff waters, sequestering soil carbon, and enhancing soil tilth. In this study, we compared five species of grasses with respect to above ground biomass production and soil respiration (i.e., CO2 flux), the latter being a robust measure of total soil biological activity. The information may help landowners select the best grass species for planting in streamside filters and buffer strips.
