Abstract |
The project studied involved the possible agricultural benefits and environmental changes that would result from applying digested sewage sludge liquid to field crops. In addition, criteria are developed that can be used in selecting sites for this method of sludge disposal. The report discusses the progress made after three year's work. Since agronomic field studies require a minimum of three years to integrate seasonal effects with measured parameters, the longer the duration of a field study, the greater the confidence level of the results. Therefore, only one year of data--detailed climatic measurements, runoff and drain water analyses, and sludge applications--were collected from a lysimeter facility. |
