  • Résumé

  • Where you live affects the quality of your food and water. A big reason for this has to do with watershed hydrology – the way water moves across agricultural landscapes.

    Matthew Helmers’ work revolves around this topic, and he shares his knowledge today.

    Tune in to explore:

    • What tile drainage is, and how it improves crop health and production
    • Why slowing water movement across the land is critical for crops and can decrease pollution in streams and rivers
    • Drainage water recycling – how it works, where it should be used, and the significant benefits
    • Sediment, nitrogen, and phosphorus – why too much in runoff water is a bad thing and how to lower the levels

    Helmers is the Director of the Iowa Nutrient Research Center at Iowa State University of Science and Technology. Learn more about his work at Iowa Nutrient Research Center (iastate.edu) and visit Iowa Learning Farms for weekly webinars and info by more experts.
