Interest in manure management and its effects on nitrogen (N) mineralization has increased in recent years. The focus of this research was to investigate the N-mineralization rates of different soil types in Coastal Plain soils and compare them to a soil from Illinois. Soils with and without dairy composted manure addition were subjected to different wetting/drying cycles [constant moisture at ...
Analysing unsaturated soil response often requires the soil-water-retention-curve (SWRC). The SWRC depends upon microstructure, which evolves with hydromechanical loading such as in-situ exposure to wetting-drying cycles. If is of interest and studied in laboratory, it essential specimens have a structure representative conditions. Simulating cycles laboratory possible albeit time-consuming fas...
Soil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9-17 years) (14) C-labeled residues of the herbicides ethidimuron (ETD) and methabenzthiazuron (MBT) and the fungicide...
