Managing natural processes in drainage ditches for nonpoint source nitrogen control

  title={Managing natural processes in drainage ditches for nonpoint source nitrogen control},
  author={Jeffrey S. Strock},
In watersheds dominated by agriculture, artificial drainage systems can efficiently and quickly transport excess water from agricultural soils. The application of more nitrogen (N) than a crop uses creates a surplus in the soil and increases the risk of N loss to the environment. We examine issues associated with agricultural N use, N transfer from artificially drained agricultural land to drainage ditches, N cycling within ditches, and options for m.anagement. Watercourses in agricultural… CONTINUE READING
