Land application of treated swine manure

Soil treatment processes can be used to remove total nitrogen and organic matter from a variety of domestic and industrial waters, and from manure. So, the Nitrogen and Organic Processing Area (NOPA) system was developed to further treat the partially treated swine manure coming from a physical/chemical treatment pilot plant. The treated effluent was stored in the tank and then reused for land irrigation and fertilization in the summer.; This research was conducted to evaluate the effects of partially treated swine manure on soil and leachate characteristics for three different application rates. After the eight week application, TKN and ammonia-N significantly increased in both soil layers and there was no significant effect on TP content. There differences between the final soil characteristics for the three different rates were insignificant. Leachate TKN and NH4-N significantly increased and there was no significant effect on TP content after manure addition. Leachate qualities showed no significant differences for the three different rates. (Abstract shortened by UMI.)...
