Soil nitrogen mineralization under two conditions was studied with the methed of sealed anaerobic incubation and sampling at given locality. The amount of N mineralization of five soil samples under seaerobic incubation con-formed exactly to the power function fermula of effective temperature summation, yet N value couldn′t reflect the charactetistics of the soil N mineralization.The correlation between the amounts of N mineralization and N supplied by soil was not obvious and the amount of N mineralization couldn′t meet with the predi-ction ...
