- Abstract
The article discusses research examining the associations of nitrate-nitrogen (N), land use/land cover (LULC), and soil drainage at multiple spatial scales. The management of non-point source pollution of water requires knowledge of the influences of land use/land cover (LULC) at varying watershed scales. The team investigated LULC, nitrate-N dynamics, and soil drainage in the Calapooia River Basin, Oregon. They selected 44 watersheds of varying sizes and monitored surface water quality monthly. Seasonal associations between nitrate-N, the proportion of woody vegetation, and poorly drained soils at differing scales defined as influence zones (IZs) were analyzed for potential correlation effects. Analysis was performed using the Hotelling-Williams test.
