| Abstract/Contents: | "A trial involving four levels of K on coastal bermudagrass was conducted over an 11-year period on a Eustis sand. Applied K increased yields by about one-third the first year with K deficiency becoming so acute on the K0 treatment in succeeding years as to virtually eliminate the stand on that treatment after the 7th year. Under low to moderate rates of applied K, the grass removed far more K than was applied. Roots penetrated to a depth of at least 244 cm and exchangeable K was affected to a depth of 122 cm. K content of the forage declined linearly from the beginning to the end of the growing season under low to intermediate levels of applied K. Optimum K content fluctuated widely both between and within growing seasons as did the degree of luxury consumption. Exchangeable K appears to be perferable to the strongacid method in identifying zones in this soil affected by the application of K. Neither method was effective in identifying supplies of native K. Findings indicate that long-term trials with plants of this kind can be of value." |
