Reducing Nutrient Loss: Science Shows What Works, C. A. J. Thompson, Matthew J. Helmers, Thomas M. Isenhart, John D. Lawrence Sep 2014

Reducing Nutrient Loss: Science Shows What Works, C. A. J. Thompson, Matthew J. Helmers, Thomas M. Isenhart, John D. Lawrence

Agriculture and Environment Extension Publications

Iowa has been working for decades to protect and improve water quality. However, progress measured toward reduction targets at the watershed scale has been challenging, and many complex nutrient-related impacts in Iowa’s lakes, reservoirs, and streams remain to be addressed. The Iowa Nutrient Reduction Strategy is a science and technology-based framework to assess and reduce nutrients to Iowa waters and the Gulf of Mexico. It directs efforts to reduce nutrients in surface water from both point and nonpoint sources in a scientific, reasonable, and cost-effective manner.


A Guide To Managing Pasture Water: Streamside Buffers, Thomas M. Isenhart, John L. Kovar, James R. Russell Jun 2008

By properly managing your pasture water, you not only provide high-quality water to maintain the health and productivity of livestock on your farm, but you also contribute to maintaining the water quality downstream – water that is used for livestock and human consumption, as well as recreational activities like fishing and swimming.

Pasture conditions that promote frequent gatherings of cattle near streams and ponds may increase sediment, nutrient and pathogen loading of these water sources from manure deposition, as well as bank erosion. However, such water-quality problems may be controlled by grazing management or pasture characteristics that alter the timing, frequency ...

Assessing The Need For A Riparian Management System (Rims), Jesse Randall, Thomas M. Isenhart Sep 2002

Assessing The Need For A Riparian Management System (Rims), Jesse Randall, Thomas M. Isenhart

Agriculture and Environment Extension Publications

Riparian management systems (RiMS) often appear complex, and assessing your stream riparian area to design one can seem a daunting task. There are many design options for RiMS that can provide multiple benefits. The best option is the design that accomplishes the most for you, for the land, and for the community. This publication provides a list of tools and considerations to help you determine what kind of RiMS is best for you and your land.

Resource Conservation Practices: Understanding And Managing Soil Compaction, H. Mark Hanna, Mahdi Al-Kaisi

Agriculture and Environment Extension Publications

Excessively compacted soil can result in many problems including a reduced yield and an increase in horsepower and fuel necessary for tillage. Learn more about this problem as well as ways to reduce soil compaction.


Riparian Buffer Systems, Richard C. Schultz, Amy Kuehl, Joseph P. Colletti, Paul H. Wray, Thomas M. Isenhart Sep 1997

Riparian Buffer Systems, Richard C. Schultz, Amy Kuehl, Joseph P. Colletti, Paul H. Wray, Thomas M. Isenhart

Agriculture and Environment Extension Publications

Streams lined with tress, shrubs, grasses , and abundant wildlife contribute to more than a beautiful landscape. Restoration of the land's natural riparian buffer system can improve water quality. prevent soil erosion, and build diversity that has been lost with modem land uses.
