2nd Annual Maryland Dairy Field Day and Tour

Wednesday, October 18, 2017 - 9:30am to 2:30pm
4240 Folly Quarter Road, Ellicott City, MD 21042
Event Type: 
Dr. Stephanie Lansing, Dr. Curt Gooch, Dr. Gary Felton, Dr. Rich Erdman, Dr. RObert Kratochvil, Jeff Semler, Matt Morris
Description / Notes: 

Dairy producers, industry professionals, and government officials are invited to learn about important innovations and technical updates conducted by faculty and staff at the University of Maryland in manure management, dairy nutrient requirements and forage production from cover crops, as well as field demonstration of manure injection.  

The benefits of an anaerobic digestion system (ADS) such as conversation of  dairy manure, feed refusals, food processing waste, and post-consumer waste into methane-enriched biogas will be discussed by Dr. Stephanie Lansing, University of Maryland, and Curt Gooch, Cornell University.  Challenges to digestion implementation will be discussed, along with practical needs to successfully manage and operate an ADS long-term. Success stories will also be shared, as well as resources for obtaining more information on anaerobic digestion and case studies.

It is well known that dairy manure pits and long-term storages pose safety hazards that are sometimes overlooked.  Some hazards are not self-evident:  Is your gypsum bedding/bedding amendment creating a dangerous situation?  Dr. Gary Felton, University of Maryland, and Curt Gooch, Cornell University  will discuss hazards including harmful manure gasses, confined spaces, drowning, and moving parts and how to eliminate or reduce them.

Many of you have heard the term: “According to the NRC Requirements…”, but just where do those NRC requirements come from?  Rich Erdman, University of Maryland, and the national chair of the committee that is revising the NRC Nutrient Requirements for Dairy Cattle will explain the how the NRC Requirements for dairy cattle evolved after World War II for animal feeding.  He will bring examples of previous Dairy NRC publications and explain the process of of defining nutrient needs such that when you hear the term the “NRC Requirements” you’ll know what it means.

 One source of forage that many of this region’s dairy farmers utilize is the fall planting of cereal grains that are green-chop harvested the following spring.  Per Maryland Cover Crop Program guidelines (, cereal grains planted as a cover crop and suppressed via green-chop in the spring are eligible for the Cover Crop Program grant payment.  And, per Maryland’s Nutrient Management Regulations, a fall application of dairy manure is allowed to a field planted to a cereal cover crop.  Learn from Dr. Bob Kratovchil about the cover crop and forage performance for select rye, triticale, wheat and barley varieties during 2016-2017 season.  

After lunch, field day participants will learn about research being conducted to investigate antibiotics presence during manure processing and the effects of different manure management techniques on the reduction of antibiotics in manure. Dr. Stephanie Lansing and Curt Gooch will guide participants along the manure trail and present preliminary findings from their study that is tracking antibiotics and nutrient transformations in dairy manure from farms with different manure management practices.

 Jeff Semler and Matt Morris, with University of Maryland Extension, will lead a discussion and field demonstration of manure injection and its benefits. Such advantages as eliminating the need for incorporation into soil while also conserving nitrogen through reduced volatilization, reduced odors and less movement of valuable nutrients off-field will be illustrated.  Participants will be able to see the machine, how it performs under field conditions, and evaluate the field post-injection."
