Irrespective of treatments, available K decreased in limed over that of un-limed soil. In general, available K progressively increased in both un-limed and half limed soils up to 60 day period of incubation but thereafter showed a decreasing trend on 90th day of the experiment. However, full limed soil showed a different trend of results. Available K increased up to 30th day, thereafter decreased on 60th day then again increased on 90th day of the experiment. The results thus revealed that available K is not retained in the soil for longer period rather it is converted to other forms at the later stage of the experiment.
