Soil Micronutreint status in chromium contaminated soil on influence of organic amendments

K Ramya Krishna and PK Sharma
To determine the influence of contamination of soil with chromium on micronutrient content in rice plants, A pot experiment was conducted in net house of Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during 2015-16. In order to neutralize the effect of the contamination of soil with chromium, organic amendments like FYM and Vermicompost were applied. The effect of soil contamination with chromium depended on the dose of chromium and the type of the neutralizing agent applied. Five levels of chromium viz., 0, 20, 40, 60 and 80 ppm with and without vermicompost @ 5 ton ha-1 and Farm yard manure @ 10 ton ha-1 were taken. Results indicated that micronutrients in post harvest soil of rice decreased with increasing Cr concentration (0, 20, 40, 60, 80 ppm). The micronutrients like copper, zinc, manganese, iron significantly increased with the application of Vermicompost and FYM. Rice crop can withstand up to 80 ppm of chromium with Vermicompost and can tolerate up to 60 ppm with FYM. Hence, toxic effect of Cr on rice crop may be mitigated by improving micronutrient status of soil more effectively with Vermicompost and FYM application.
