Kumararaja, P. Shri
Designation : Scientist
Discipline : Soil Science-Soil Chemistry/Soil fertility/Soil microbiology
Division : Aquatic Animal Health and Environment Division
Specialization : Soil Science-Soil Chemistry/Soil fertility/Soil microbiology
Research areas:
  • Improvement of Pond bottom and water quality by chemical means.
  • Product development for dissolved oxygen enhancement in pond water.
  • Carbon sequestration through biochar from pond sediment sludge.
Brief profile:

After taking Masters in Soil Science and Agricultural Chemistry in 2005 and PhD in Soil Science and Agricultural Chemistry in 2015 I am working in CIBA since 2013 on “Treatments for improvement of pond bottom and water quality. I currently work in division of Aquatic Animal Health and Environment Division in CIBA. I have worked on oxiding agents for enhancing the organic matter degradation, environmental monitoring of shrimp and fish farms.I have contributed to 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 amendment for removal of nutrients from discharge water.
