Water Quality Index for Agricultural Runoff Tool
The Water Quality Index for
Runoff from Agricultural Fields (WQIag) is a qualitative, multivariate tool
that characterizes the quality of water exiting as surface runoff at the field
scale. It is simple, transparent and easy-to-use web-based system. In combination with the published literature,
the WQIag captures heuristic knowledge of different disciplinary experts such
as soil scientists, agronomists, nutrient management specialists, and
irrigation specialists and conservationists. Based upon the field
characteristics, crop management practices (nutrient, tillage, pest control,
irrigation and drainage) and structural practices; it ranks runoff water from 1
to 10 where 10 being the best and 1 being the worst. The presentation will
provide an overview of the tool with a demo and discuss how it can be used by
NRCS field staff and others in evaluating and tracking effectiveness of
conservation practices in improving water quality over time and space.
application for continuing education credit for Certified Crop Advisors
(CCAs) and members of the American Registry of Professional Animal
Scientists (ARPAS) has been submitted.
