摘要: Laboratory aerobic incubation was conducted for 161 d to study N mineralization and the changes of organic fractions nine different manures (3 chicken manures, 3 pig cattle manures) from farms/locations. Results indicated that significant (P<0.01 or P<0.001) difference existed in between manures. The rapid occurred during 56 84 incubation. First order exponential model can be used describe while quadratic equation predict An average 21, 19 13% added manure, manure mineralized Amino acid-N main source mineralization. amino together with ammonium could explain significantly 97 96% variation manured soils are two determining potential contributed more than N.
