The nature of the relationship between diversity and important ecosystem functions may have practical implications for agriculture. Observed relationships vary; however, most evidence suggests that at relatively low levels of diversity, increasing the number of species in a community should lead to increased productivity. Because of their low diversity, annual row-crop systems may be particularly sensitive to changes in the number of crop species. In this study we are investigating how increasing cropping-system diversity, through crop rotation and cover crops, affects crop yields in the absence of chemical inputs.
