Although nutrient losses from agricultural fields have been documented to be significant, nutrient pollution can also originate from a variety of sources. The scope of this program, therefore, includes non-agricultural ecosystems and natural resources also. The research directly falls under the first two aspects of the "Management of Nutrients, Wastes and Pesticides", the largest Thrust Area of the Department. All research is reported under CRIS Project No. FAES-SWS-04835.
In a first of its kind, field research using dN15 techniques, in the semi-arid tropics of India, is being conducted to determine N-balance under both lowland and upland rice production systems, through the Indo-US Agricultural Knowledge Initiative. Simultaneously, water savings are also being documented. Modeling and up-scaling the information to watershed level are also being attempted through this project.
