The application of animal waste on farm land is currently considered as a safe method to dispose the excreta from farm animals because it provides an easy outlet to alleviate envaronmental danger associated with animal excreta. In most published studies, animal waste is viewed as a good source of nitrogen, phosphorus and potassium (NPK). Little attention has been given to minor chemical compounds present in the contents of animal wastes. Some classes of compounds which are suspected to be phytotoxic have been reported to be present in animal waste. Identification and mode of action of such compounds present in animal waste is important because agricultural practices which are considered as environmentally safe today may become a hazard to agricultural crops in the future. Fatty acids are known for germination inhibiting activity. The objectives of this study were to identify fatty acids present in dairy and hog manures and to investigate their biological effects on germination of sorghum seeds. Six fatty acids were the subject of this study. All six fatty acids were found in the content of dairy and hog manures. The rate of germination of sorghum seeds was significantly reduced with exposure to all six fatty acid. Long chain fatty acids were more toxic than short chain acids. Similar patterns of action were observed in the alpha-amylase activity and physiological water uptake. |
