Abstract/Contents: | "The contribution of microorganisms to the development of water repellency in an initially non-repellent golf course soil was investigated. Soil was amended with a range of nutrients and biocides in order to control the C:N ratio and inhibit either bacterial or fungal processes and then incubated in a controlled environment for one week. The nutrients added were formed from tryptone soya broth, ammonium nitrate, and glucose in order to obtain C:N levels of 1:1, 10:1, and 100:1. The application rate was equivalent to 25 kg N ha-1 for all treatments. Higher levels of carbon substrate addition increased levels of microbial respiration measured using a gas chromatograph. After incubation, the level of water repellency also increased with increasing levels of carbon. Severe levels of water repellency only developed for the highest carbon substrate addition (18 mg g soil-1) for all soil except when treated with a fungal biocide. Soil treated with a bacterial biocide developed higher levels of water repellency than an untreated soil, suggesting that microbial competition can suppress the development of water repellency. The biocide treatments suggest that fungi are the component of the microbial community that causes water repellency." |
