Abstract/Contents:"Some turfgrass areas grow and prove satisfactory with a very low natural supply of nitrogen. In contrast I other turf plantings require high nitrogen to repair their cover or provide the density required for use. Fortunately I several of our common turfgrass species can provide turf with either high or low nitrogen. Also I it is accepted that some turfgrasses respond to nitrogen far more vigorously than others. With this premise I it seems that' nitrogen fertilizer can be used to manage for one species of grass vs. another. Possibly we have used N too much for greenness and density while overlooking its influence as a management tool in the ecological balance of species. In considering the role of N in manipulation of species dominance, we must start with two species that tolerate the given climate. The more unlike the two grasses, within the climatic tolerance, the greater should be the chance for manipulating the dominance of the desired grass species. Among growers, it is believed that bermudagrass can overcome many other species with high N. Also, high N is an accepted cause of red fescue loss in Kentucky bluegrass turf. In tests to date, we have been able to reduce bentgrass in Kentucky bluegrass turf with fall fertilization.-as compared with spring fertilization. We have encouraged zoysia in cool-season turfgrasses in our climate with low N or N stimulation at the start of hot weather. The leverage with N in reducing annual bluegrass in bentgrass is not as great as we would like to find. Also, our testing experience suggests that various factors can overwhelm N use in species dominance."
