| 英文摘要 | The variations of phosphorus (P) in animal manure during freeze-thaw cycles (FTCs) profoundly influence on non-point source P loss in winter. Therefore, understanding how FTCs influence the physicochemical properties of animal manure and its P availability is crucial. In this study, the freeze-thaw treatment was performed by incubating the pig manure at -20 degrees C for 12 h and at 18 degrees C for 12 h. The freeze-only treatment was maintained at -20 degrees C as a control. In addition, the pig manure was kept at two moisture levels during the FTCs and sampled every five cycles. Six forms of Pin the manure were extracted and analyzed. After 30 cycles, the dissolved organic carbon had increased from 10.49 to 13.56 g/kg, and the pH had decreased from 6.25 to 5.77. The particles originally >1000 mu m were broken into particles <250 mu m. The forms of P in manure shifted from Ca-P, occluded P, and residual P towards NH4Cl-P, Al-P and Fe-P, resulting in a 23% increase in bioavailable P. These variations were highly coincident with the increase in moisture content and FTC frequency. The proportion of particles <38 mu m increased by more than 2% after the FTCs, and the manure P was mainly concentrated in these particles, which might be readily washed away by the melt water. Overall, the study indicated that FTCs could enhance the bioavailability of P in pig manure and the mobility of particle-associated P. These findings are significant for reducing animal manure pollution in freeze-thaw season. (C) 2019 Elsevier Ltd. All rights reserved. |
