Subject Soil Science
 
Description Dr. Kanwar L. Sahrawat received M.Sc. (1969) and Ph.D. (1973) degrees in Soil Science and Agricultural Chemistry from the Indian Agricultural Research Institute (IARI), New Delhi. Dr. Sahrawat was awarded Seth Lachhi Ram Chudiwala medal in 1974 by IARI for his Ph.D. thesis research on the development of nitrification inhibitors from indigenous resources, as an outstanding contribution in the area of agricultural chemicals.
Dr. Sahrawat started his scientific career as a research associate (1973–1975) in ICRISAT, Patancheru, India. He successively worked as a post-doctoral research fellow (1975–1978) with Dr. F. N. Ponnamperuma in IRRI, Philippines, Soil Chemist/Senior Soil Chemist (1978–1991) in ICRISAT, India and principal soil chemist (1991–2001) at the West Africa Rice Development Association (now Africa Rice Center) (WARDA). Dr. Sahrawat spent his entire professional career working in the CGIAR system. In WARDA, he was also Coordinator of the project on “Integrated management of iron toxicity in lowland rice” and the Task Force on “Problem soils”. During his stint with ICRISAT (India) and WARDA (Bouake¢, Ivory Coast), Dr. Sahrawat had an opportunity to establish soil chemistry laboratories. During 1983–1984, Dr. Sahrawat was on a sabbatical leave, from ICRISAT, at the Soil Science Department, University of Wisconsin-Madison, USA and worked with Professor D. R. Keeney. Since May 2002, Dr. Sahrawat has been working as a consultant/visiting scientist at ICRISAT-India; and his research pertains to the diagnosis and management of nutrient problems in the watersheds in India, for enhancing productivity and quality of rainfed cropping systems.
Dr. Sahrawat has published over 300 technical papers including 200 papers in refereed international and national journals, bulletins, edited conference proceedings and chapters in Advances in Agronomy, Advances in Soil Science, Encyclopedia of Soil Science, Soil Science Society of America Special Publication no. 58 and other books. He has extensively conducted research on the chemistry of nitrogen, phosphorus and iron, both deficiency and toxicity. He led research on the chemistry of wetland soils and the management of acid soil related infertility in uplands in West Africa. This research has been very rewarding scientifically and for practical management of “opportunity soils”. Dr. Sahrawat always applied basic Chemistry principles for developing or improving existing methods of soil and plant analysis for diagnostic and routine analyses purposes. This effort has resulted in the development of techniques for rapid and precise analysis of soil and plant materials.
Dr. Sahrawat has served as an Affiliate Faculty of the post-graduate school, APAU (now ANGRAU) (1978–1991, 2007-), Rajendra Nagar and University of Ghana (1993–2001), Accra, Ghana and supervised the thesis research of M.Sc. and Ph.D. students in the general area of Soil Chemistry, Biochemistry, Fertility and Plant Nutrition. Dr. Sahrawat served as a member of the International Council on Plant Nutrition (1978–1993) and Adviser (1998–2004), International Foundation for Science, Stockholm, Sweden. He is a recipient of the fellowship (1999) of the National Academy of Agricultural Sciences, India. Dr. Sahrawat received a certificate of appreciation from WARDA in 2001 for his outstanding contribution to rice research and development through service as a Principal Soil Scientist.
