| Abstract/Contents: | "Twenty-four soils were used in this investigation, which had acidity levels ranging from very strong acid (pH = 3.56) to moderate acid (pH = 5.95). Concentrations of exchangeable aluminum ranged from 12 ppm Al to 1230 ppm Al and exchangeable calcium from 5 to 1550 ppm Ca. The available phosphate by the sodium bicarbonate soil test ranged from 0.5 to 50 ppm P. The clipping yields of annual bluegrass or bentgrass grown under greenhouse conditions were not closely related to the pH levels of the soils even though a trend showing a general increase of yields with pH was observed. Low pH can inhibit radical development of annual bluegrass. However, the results of the present study gave no clear indication that annual bluegrass is less tolerant to soil acidity than the bentgrass. The pH did not account for much variability of the clipping yields for either grass. The differential tolerance to pH between the two grass species was not substantiated by the present study. Increased exchangeable soil aluminum reduced clipping yields of both grasses. Soluble ionic aluminum reduced clipping yields of both grasses. Soluble ionic aluminum is known to inhibit cell division, root growth and elongation. There was no differential growth response between the two grass species to the Al stress as anticipated. Clipping yields of bentgrass and annual bluegrass responded highly to increased available soil phosphate. Bentgrass reached a maximum yield between 15 and 20 ppm P by sodium bicarbonate soil test. Annual bluegrass response correlated to higher levels of available soil phosphate. This indicates that annual bluegrass has a greater phosphate requirement than bentgrass. In the present study, an apparent function of available soil Ca for both grasses was to stimulate the plant utilization of available soil phosphate. Maximum clipping yields were reached at a lower level of available soil phosphate when the quantity of available soil calcium was increased to an adequate level. While phosphate can enhance the growth of the two grasses under Al stress, increased calcium availability can also benefit plant growth by promoting plant utilization of available soil phosphate." |
