Dr. P. Kumararaja

After taking Masters in Soil Science and Agricultural Chemistry in 2005 and Ph.D. in Soil Science and Agricultural Chemistry in 2015 I am working in CIBA since 2013 on “Treatments for improvement of the pond bottom and water quality. I currently work in the division of the Aquatic Animal Health and Environment Division in CIBA. I have worked on oxidizing agents for enhancing the organic matter degradation, environmental monitoring of shrimp and fish farms. I have contributed to the development of improved methods of pond preparation. I have interests in pond bottom sediment quality improvement by Advanced Oxidation Technology. Pond water quality management by biopolymer-based adsorbents and ion exchange materials. Efficient and economic utilization of sludge by converting to biochar and use it as an amendment for removal of nutrients from discharge water.

• Improvement of culture and post-harvest pond bottom soil and water quality.
• Carbon sequestration through biochar from pond sediment sludge.
• Hydrogeochemical characterisation of inland saline waters and their suitability for aquaculture
• Seasonal variation in carrying capacity of brackishwater sources for shrimp aquaculture.
• Antibiotic degradation pathways and kinetics in the aqueous system.

• Gold medal for standing first in Soil Science and Agricultural Chemistry during M.Sc. at Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh.
