This webinar features Dr. Ehsan Ghane addressing issues related to
drainage of crop fields and nutrient management. When excess phosphorus
from farmland reaches downstream water bodies, it causes eutrophication
and harmful algal blooms like the ones in Lake Erie and Saginaw Bay.
Much of this phosphorus is soluble and readily available for algae
growth. Most of this phosphorus is transported by subsurface drains. In
this presentation, two drainage conservation practices including
controlled drainage and saturated buffers will be discussed.
