Changes in manure management between CEAP I & II


Changes in manure management between CEAP I & II

Watch the Recording

The United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) evaluates conservation trends and effects on cultivated cropland through the Conservation Effects Assessment project (CEAP). CEAP uses natural resource and farmer survey data along with physical process modeling to estimate the environmental impacts of conservation practices on cultivated cropland. The first set of farmer surveys was conducted in 2003-06 (CEAP I). Now, comparison data from farmer surveys conducted in 2013-16 (CEAP II) make it possible to estimate shifts in conservation adoption and effects between the CEAP survey periods. Between the two survey periods, acres receiving manure nutrients increased substantially. While soil testing increased, increased manure application rates and load-to-loss disparities indicate continuing challenges. Along with manure nutrient losses to the waterways, losses of pathogens, antibiotics and other contaminants are also a problem that must be addressed with the increased usage of manure. Texas A&M AgriLife is currently addressing these issues through on-the-ground research aimed at developing conservation practice protocols to help reduce and/or eliminate these manure contaminants helping to reduce the impact on soil and human health.

An application for continuing education credit for Certified Crop Advisors (CCAs) and members of the American Registry of Professional Animal Scientists (ARPAS) will be submitted.

Presenters include:

  • Dr. Lee Norfleet, USDA-NRCS (retired)
  • Dr. Eunsung Kan, Texas A&M University
  • Evelyn Steglich, USDA-NRCS
  • Tibor Horvath (moderator), USDA-NRCS

Handouts (PDF format) will be available the day of the webinar at the live webinar information page. Find out more about this webinar and future webinars by the Livestock and Poultry Environmental Learning Community (LPELC).

FAQs for Learn Calendar Users:

Will a recording be available?

That is entirely up to the host of this webinar/online event. If this is an Extension Foundation hosted event - we will update this calendar listing with a link to the recording usually within 48 hours. Keep in mind, many of the offerings found here in Connect Extension are brought to you by your colleagues across the system. While we encourage them to update their listings with recordings, it is entirely up to them.

How do I know if it is an Extension-hosted event?

Extension Foundation posts publicly our events to two calendars - the Extension Foundation Member Calendar and the Opportunities for Cooperative Extension Calendar.  All other events coming from across Cooperative Extension are posted to the Learn Calendar or to one of the regional calendars. All calendars populate to the same main calendar on Connect Extension. To tell the difference between what events are posted to what calendars easily, you'll see the name of the calendar posted above the title of the event if you scroll to the top.

What if I have trouble accessing this webinar?

Please contact the author of this calendar event. The individual that posted this event will have their username automatically listed at the bottom of the body of their post, right above the social media buttons. When you hover over that name, you are able to send them a private message.

The Extension Foundation was formed in 2006 by Extension Directors and Administrators. Today, the Foundation partners with Cooperative Extension through liaison roles and a formal plan of work with the Extension Committee on Organization and Policy (ECOP) to increase system capacity while providing programmatic services, and helping Extension programs scale and investigate new methods and models for implementing programs. The Foundation provides professional development to Cooperative Extension professionals and offers exclusive services to its members. In 2020 and 2021, the Extension Foundation has awarded 85% of its direct funding back to the Cooperative Extension System, 100% of funds are used to support Cooperative Extension initiatives.
