Conversion of pastureland into cropland has occurred at a rapid rate on the central to northern Great Plains. A reduction in total acreage of pastureland from this conversion has resulted in a decline of total numbers of beef cows in the same region. One method to mitigate the decline in cow numbers is to increase carrying capacity of the remaining pastureland acres. Introducing warm-season annual grass species into perennial coolseason grass pastures to increase dry matter production during the mid-summer time period that perennial cool-season grasses would be most dormant is one strategy that may be able to boost production. An increase in production during this time period could result in an overall increase in total land area biomass production to be able to maintain or increase the number of cow units per acre of pastureland.
