Learners enrolled: 967
This course will provide extensive discussions on the chemistry of inorganic and organic soil components, soil solution–solid phase equilibria, sorption phenomena, kinetics of soil chemical processes, redox reactions, soil pollution, pollutants-soil solution interactions, and analytical techniques for assessing soil pollution. Each topic will contain sample problems and explanations of parameters and terms. These should be very useful to students taking their first course in soil chemistry. This is a comprehensive and contemporary course for undergraduate students in soil science and for students and professionals in environmental chemistry and engineering, marine studies, and geochemistry.

Prof. Somsubhra Chakraborty

IIT Kharagpur
I am currently serving as an Assistant Professor (Soil Science) at the Agricultural and Food Engineering Department, Indian Institute of Technology Kharagpur. I was awarded various prestigious fellowships including the Australia Awards Fellowship from the Australian Department of Foreign Affairs and Trade. I did my undergraduate and M.Sc degrees from BCKV and PAU in India and PhD degree in Agronomy (Soil Science emphasis) from Louisiana State University, USA. I started my career as a post-doctoral researcher at West Virginia University, USA. I joined IITKgp as faculty in 2016. I am passionate about the use of proximal and non-invasive sensors for soil management. I have around 50 international journal publications. I am currently serving as the member of the editorial board of Geoderma, the global journal of soil science.
