Abstract: Pot experiments were conducted in the net house of Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, B.H.U., Varanasi in alluvial soil during 2015-16 using maize-mustard cropping sequence to study the effect of chelating compounds on chemical properties of post-harvest chromium contaminated soil after maize and mustard. Five levels of chromium viz. 0, 5, 10, 20, and 30 ppm with and without five types of chelating compounds viz. EDTA, DTPA, Oxalic Acid, Citric Acid, and Humic Acid were applied. All the treatments of chelating compounds were applied to maize in kharif season and mustard was taken in rabi season as residual crop after harvesting of maize crop. pH, EC (dSm-1), organic carbon (%), N, P, K and Cr content in chromium contaminated post-harvest soil were determined after harvesting of maize and mustard crops. Results indicated that pH, EC, OC, N, P and K content decreased with increasing level of chromium. It was also found that pH, EC, OC, N, P and K content increased with application of chelating compounds, however; DTPA, humic acid and oxalic acid buildup the post-harvest N, P and K content but not significantly. Soil from maize and mustard harvested pot trending toward increasing DTPA extractable chromium with increasing rate of chromium. It was noticed that DTPA extractable chromium decreased in post-harvest soil after maize and mustard harvesting with application of chelating compounds.
