An investigation was undertaken to examine the changes in available potassium status in an alluvial soil under intensive cropping and fertilizer use for seven years, using water, 0.01M CaC1, neutral normal ammonium acetate and NHF plus DTPA as coil tests. While all the four tests employed were found fairly effective, ammonium acetate proved to be the best in detecting the treatmental differences. CeC1, (001M), ammonium acetate and NH.F plus DTPA showed highly significant positive relationships with yield of crops raised in the eighth rotation.
