Phosphorus in cattle feed is directly related to the amount of phosphorus excreted in their manure. In some areas, phosphorus is limiting the amount of manure that can be applied to crop fields. Join us to learn more about a current research project that is examining the bioavailability of phosphorus for dairy cattle as a way to manage feed nutrients and reduce excretion in the manure.

Manure Experts. You may have noticed a new link on all of our web pages--the "Manure Experts" database. This database is searchable by location or topic to find people who can help answer your questions. If you are an expert in some area of animal agriculture and environmental stewardship there is a link toward the bottom where you add yourself to the database. More...
Manure Expo. The debut of the North American Manure Expo in Canada was met with rave reviews, both for the content of the program and the organization of the event. the biggest attention-getter was a device known as the 'lagoon crawler'. Manure Expo website | Show Guide | Facebook. A sampling of news coverage of the event: Guelph Mercury | Farms.com | Progressive Dairy
Nitrate Tracking. The US Geological Survey is using real-time nitrate monitoring in the Mississippi River Basin in order to study the patterns of nitrate pulses as they relate to weather, precipitation and seasonal flow. The data can also be used to alert water treatment plants when to start up the nitrate removal system. More...
Manure Contaminants. The US EPA has released a report "Literature Review of Contaminants of Livestock and Poultry Manure and Implications for Water Quality". This report summarizes science and includes information on antibiotics and hormones, among other topics. No policy recommendations are made. More...
Climate Report. The USDA Office of the Chief Economist is inviting public comments on a report that outlines user-friendly ways for farmers, ranchers, and forest landowners estimate greenhouse gas emissions and evaluate the benefits of reducing emissions, or increasing carbon sequestration.

Ecosystem Services. A recent workshop hosted by the USDA Economic Research Service and Farm Foundation focused on the economics of agricultural programs that pay for desirable environmental practices as well as behavioral considerations and adoption factors. The presentation slides from that workshop are available by following the link. More... | Related: LPELC webpage on Market Based Conservation
State Program Highlights
Have a state project or program you would like to see in this section? Email the details to email@example.com.
Dairy Cents App. Pennsylvania State University has released "DairyCentsPRO", an app that allows users to enter farm-specific information to calculate feed costs compared to production and track that over time. The app also monitors feed management metrics such as dry matter intake, milk nitrogen efficiency, phosphorus intake and excretion and more. The app is currently available in a producer version ($9.99) and consultant version ($14.99) in the iTunes store with an Android version being planned for this fall. Search "dairycentspro" in the app store.
Minnesota Nitrates. The Minnesota Pollution Control Agency recently released a study that indicated 70% of nitrate in surface waters came from cropland. Manure was cited as the third most abundant nitrogen source on cropland behind commercial fertilizer and legume fixation. The use of tile drainage was also mentioned as a contributing factor in one area of the state. Improving the nitrogen use efficiency of fertilizer was the major recommendation to reduce loading.

Cow Power Movie. Most of you are probably already aware of the "Cow Power" program in Vermont that uses anaerobic digestion to produce electricity, but did you know there is a movie? "Cow Power: The Film" is a documentary about this program and its impacts. More...
Manure Biosecurity. With the spread of porcine epidemic diarrhea (PED) becoming a concern, farmers and custom manure applicators are reminded to follow some basic guidelines to prevent the spread of this disease through manure hauling and application.

Monoslope Beef Facilities. Iowa State, South Dakota State, and USDA Ag Research Service will be hosting a conference on monoslope beef barns November 21, 2013 in Sioux Falls, SD. The morning session will cover air quality and nutrient management. The afternoon will include panel discussions on management by farmers with these buildings and a panel comparing cattle performance in different types of buildings. For more, contact Beth Doran firstname.lastname@example.org.
Waste to Worth II. We are excited to announce that the follow up to Waste to Worth "Spreading Science and Solutions" will be held in Seattle, Washington and is tentatively planned for late spring, 2015. If you would like to be part of the planning committee, contact Joe Harrison email@example.com.
