Abstract:	To find out a rapid and reliable procedure for estimating soil available nitrogen (N), the standard alkaline-permanganate extraction and its modification to include soil NO3 were evaluated. The N values obtained with the standard method showed a poor correlation with the mineral N of incubation test and plant uptake (r=0.36 and 0.37 respectivelyP<0.05 in both the cases) whereas the results obtained with the modified method gave highly significant correlations (r=0.84 and 0.76 respectively.P<0.01 in both the cases). The data supplied further verification of the modified alkaline-permanganate method for assessing N availability in soils.
