Edge-of-field Practices


Dan Jaynes Iowa Learning FarmsJune 2014: Dan Jaynes, Saturated Buffers for Nitrate Removal (43 min.)

Riparian buffers are a proven technology for reducing sediment, phosphorus, and nitrate contamination of surface waters. Unfortunately, in tile-drained areas of the Midwest, buffers are not particularly effective in removing nitrate because the tile lines discharge directly into surface waters, bypassing the buffers. Saturated buffers are an attempt to “re-plumb” the riparian buffer, redirecting some of the field tile drainage into the buffer as shallow groundwater flow. 

By watching this webinar, you will be able to:

  • Explain how a saturated buffer works
  • Determine the basic considerations for siting and designing a saturated buffer
  • Identify the effectiveness of a saturated buffer for nitrate removal
  • Consider the potential application of saturated buffers in Iowa

Tom Isenhart Iowa Learning FarmsSeptember 2014: Tom Isenhart, Streambank Erosion

Do we know enough about stream bank erosion to mitigate damage to stream ecosystems? There is a growing body of evidence that much of the sediment and phosphorus delivered to the surface waters from farm fields originates from streambed and stream bank erosion. This presentation discusses the effects of altered watershed hydrology, sediment build-up from historical agricultural erosion of uplands and riparian land management on streambed and stream bank erosion.

 

 

Cruse Iowa Learning FarmsApril 2014: Rick Cruse, Soil Erosion in Iowa - How Much is Really Happening?

This webinar talks about soil erosion that is ignored or unreported by most agencies, and even by the Iowa Daily Erosion Project. Cruse is part of research efforts more clearly identifying soil erosion that occurs in ephemeral gullies – the small gullies formed by water runoff typically tilled shut by farm operations. Many fields are scarred by gullies that channel soil and chemicals into streams, which are not accounted for in Iowa State’s erosion estimates or those typical of the Natural Resources Conservation Service.
