Looking Ahead to November: Long-term study of manure on root crops

An eight-year study of manure in crop rotations that include root crops (sugar beets and potatoes) is taking a very comprehensive look at manure use. Researchers are studying everything from yields, soil health, characteristics of the harvested crop, nutrient runoff and leaching, and much more. Join us for a look at the results to date and what is being learned about timing and rate of manure application in relation to the value of food crops and environmental impacts. November 17, 2017 at 2:30 pm EST (1:30 CST; 12:30 MST; and 11:30 a.m. PST) A flyer will be posted on the Upcoming Webcasts page as soon as it is available.

Speakers: Amber Moore, Oregon State University and April Leytem, USDA Agricultural Research Service (Idaho).

Water Quality

  • The latest Livestock Environmental Management News issue is available from North Dakota State University. Some of the topics include erosion, manure spreader calibration, soil microbial activity, and much more...
  • Research from Pennsylvania State University shows that injecting manure instead of surface broadcasting significantly reduces estrogen. To a lesser extent, dissolved phosphorus and dissolved organic carbon were also reduced. News release... | Journal abstract...
  • The phosphorus index, as most of us know it, is a tool to assess the risk of P runoff through surface flows. A significant amount of cropland in the United States uses subsurface drainage to control water levels. University of Delaware research combined information from and existing soil core library and newly-collected data to develop phosphorus index scores for subsurface P.

  • bottles of veterinary pharmaceuticalsVeterinary pharmaceuticals, when detected in water, are generally assumed to move via manure application, surface runoff, or leaching. Texas Tech researchers examined the potential for airborne transport via particulate matter (dust) to waterbodies. They sampled wetlands that were <15km from feedlots and found at least one pharmaceutical in every one. They suggest that this method of transport should be studied further to determine if it warrants inclusion in risk assessments. Journal abstract...

Manure Storage.  A September webinar from USDA NRCS looked at industry and USDA Natural Resources Conservation Service (NRCS) standard codes and references, design loads and critical load combinations, and basic components of a typical NRCS Animal Waste Management (AWM) retaining wall.

Antibiotics. Researchers in Denmark looked at the persistence of different antibiotics in anaerobically digested pig manure. They identified specific drugs that are degraded rapidly and some that are persistent. Journal abstract...

  • An analysis done by researchers in China and Australia examined 141 other studies that involved using animal manure to replace some or all inorganic fertilizer. They concluded that using manure can improve crop yields, soil health, air, and water quality. News article... | Journal abstract...
  • Manure application has significant positive impacts on soil. In turn, this reduces runoff and soil erosion (via Nebraska Extension). Read more...

  • An international research team co-composted biochar with manure. The process resulted in an organic coating on the surface of the biochar that improved nutrient storage and the ability of the char to interact with other soil organics. News release... | Journal article...

Animal Welfare. A study from Purdue University examined the impact of California's 2008 animal welfare laws on egg production and prices. California produces fewer eggs than before the law and at a higher cost. Read more...

Air Quality. USDA NRCS and EPA have published "Agricultural Air Quality Conservation Measures: A Reference Guide for Livestock and Poultry". The 79-page guide includes conservation measures that can be used to improve air quality related to common animal agriculture activities such as manure application, feed processing, and grazing management. The guide also includes a table listing the effectiveness of different practices in mitigating several common air pollutants. Download the guide...

cow grazing in pasturePastured Livestock. Several upcoming or recorded USDA NRCS webinars may be of interest to those of you that work with grazing animals. Raising non-ruminant livestock on pasture is becoming more common and there are opportunities for conservation in this production system.  An upcoming (November 14, 2017) webinar will be held on "Raising dairy replacement heifers on pasture". A third webinar looks at "To fence or not to fence" relative to streams when planning a prescribed grazing system and riparian buffers.

Farmer Stewardship.

  • A California dairy received a Nutrient Recycling Challenge award from U.S. EPA. The farm has installed a manure gasification system capable of processing all the manure from their 1000 head cow herd. Read more...
  • A poultry and swine farm in North Carolina received the Farm Environmental Excellence Award from the US Poultry and Egg Association. They were recognized for their use of GPS and variable rate application of litter to their crop fields as well as covered litter storage. The family uses a forced air composting system to dispose of mortalities and a high-tech system to maintain conditions in the houses for optimum bird comfort. News release... | Video...
