Insights from intensive water quality sampling in a drained agriculutral field

Abstract

Excessive nitrate export from agricultural activities has been recognized as non-point sources of contamination to receiving water bodies. Researchers have mad considerable efforts to quantify the fate and transport of nitrate export from agricultural fields, including field investigation, numerical modeling and data mining in large datasets, etc. Limited application of high frequency sampling has been conducted in field scale tile drainage systems and shallow groundwater. We hypothesized that high resolution concentration data in time and in space, will provide the valuable info necessary to describe and predict the movement and fate of nitrate in and from agricultural fields.
