Impact of Flash Flood oil Agricultural Land in Jaipur Region of Rajasthan

Flash flood in July 1981 in and around Jaipur (Rajasthan) damaged productive fertile agricultural lands by the deposition of sediments varying from 20 cm to 2.5 m in thickness. Fine sand constituted more than 90% of the sediments, the remaining amount being clay and silt. The sediments were poorer in organic matter content (organic carban 0.02 to 0.14%) than the soil buried underneath (organic carbon 0.11 to 0.20%). Not much variation was observed in the content of available P₂O₅ but available K₂O was low in the sediments (103 to 195 kg/ha) as compared with values in the soil below (224 to 455 kg/ha). A large number of samples indicated deficiency of Zn and Mn in the sediments while available Fe appeared to be in the optimum range and the status of available Cu was also just adequate.
