Abstract/Contents: | "Mineral nutrients and population dynamics of soil microbes in the root zones of zoysiagrass infected by Rhizoctonia solani AG2-2 and that of healthy plants were sampled from ten golf courses using a cup cutter(diameter 10 cm times x 8 cm deep). Analysis of variance(ANOVA) showed significant differences in content of NO3-N(P = 0.05), NH4-N(P = 0.1), and K(P = 0.1) between infected and healthy samples. The content of NO3-N in the soils of large patch was 9.49 mg/kg and that in soil of healthy plants was 7.02 mg/kg. However, the content of NH4-N in the soil of large patch was 12.02 mg/kg whereas 14.40 mg/kg for the soil under the healthy plants. The content of K in the soil of large patch was lower than that of soil of healthy plants. There was few numbers of Pseudomonas colonies In the soils of large patch compared to that of healthy plants. These results indicated that the content of NO3-N, NH4-N, and K and the microbial population dynamics in root zones correlated to occurrence of large patch." |
