Research on calcium absorption capacity of acrisols
Lime application is one of effective methods to reclaim acrisol. However, it is necessary to learn more about the nature pf soil Ca absorption to improve the performance of lime application. Reaction speed of Ca absorption is very high, from 10-120 minutes, while 80-90% of Ca amount was absorbed in first 3-10 minutes. Ca absorbed rate is 10.42-43.6%, highest at Ca2+ concentration 0.04mg/ml.
