Augmentation of nitrogen and phosphorous mineralization in chromium contaminated soils using organic amendments
Author(s): Vipin Kumar and Pramod Kumar Sharma
Abstract: Due to wide industrial use of chromium, it is considered a serious environmental pollutant. An incubation experiment was conducted to study the nitrogen and phosphorous mineralization in chromium contaminated soils treated by organic amendments in Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during 2016-17. Five levels of chromium viz. 0, 20, 40, 60 and 80 ppm with and without three organic amendments viz. Vermicompost @ 5 ton ha-1, Farm Yard Manure @ 10 ton ha-1 and Sewage Sludge @ 20 ton ha-1 treatment were applied in the experiment. Result showed that N and P mineralization significantly decreased as level of chromium increased, while application of organic amendments significantly increased the N and P mineralization as compared to their respective chromium treatment. Maximum and significantly higher increment in N and P mineralization was found with the application of vermicompost @ 5 ton ha-1 followed by farm yard manure @ 10 ton ha-1, followed by sewage sludge @ 20 ton ha-1.
