However, those treatments containing high proportions of alfalfa also attracted higher numbers of herbivorous keystone species. In general, the treatments with the largest concentrations of alfalfa also had the highest numbers of aphids. Residual effects of alfalfa and brome grass cropping on yields of wheat grown for subsequent 15 years. The alfalfa-wheat strip-crop treatment demonstrated yields similar to alfalfa and wheat monoculture yields. The present study pointed to the critical role of legumes, especially perennial alfalfa, for increasing the energy efficiency of a cropping system. Applying a selective herbicide to the no-till intercrop treatment would have stunted alfalfa growth and therefore would probably have benefitted wheat growth and production. Prices of alfalfa vary with production levels in local markets and are not eligible for government deficiency payments. However, honey bees or alfalfa leafcutting bees were seen actively foraging in the soybean plots. It increased the case definition specificity so that alfalfa sprouts were identified as the food vehicle with relatively few cases.

In the stripcropped treatment, four samples were collected each from wheat strips (till) and from alfalfa strips (no-till) in a grid pattern. This suggests that herbicide was more effective at reducing weeds after alfalfa than after wheat in this year. These examples are from corpora and from sources on the web.
