How the Chicken Industry Operates
• Five Delmarva chicken companies
• 1,600 farm families growing chickens
• Companies provide chicks, feed, bird health
programs, bedding material, propane gas, and
company oversight
• Growers provide land, houses, electricity,
water, and day to day management

How Much Manure is Produced?
How Much Manure is Produced?
• University of Delaware/Delaware Department
of Agriculture Data show:
• Chicken manure production in Sussex County
is only 20% of EPA estimates
• Manure nitrogen concentration is only 40% of
EPA estimates
• Manure phosphorus concentration is only 60%
of EPA estimates
Delmarva’s Chicken Industry
Pollution Contributions
• Delmarva chicken producing counties = 7.7%
of Chesapeake Bay Watershed
• Delmarva chicken manure is responsible for
just 6% of all Chesapeake Bay nitrogen from all
Maryland sources

Locally Produced Organic Fertilizer
•

•
•
Add micronutrients to aid in plant growth
Is a slow release fertilizer
Has a value of about $100/ton as a fertilizer
Selling for about $25 per ton
Not a waste product
In short supply in parts of Delmarva
So, what have we been doing?
Phytase
• Less phosphorus in = less phosphorus out
• Phytase use = 30% reduction in excreta P

Manure Transport
• Maryland
– Chicken companies match state dollars for their
growers‘ costs
– 85% moved out of Lower Shore Counties
– 77% went to alternative uses
Manure Transport
• Delaware
– 31% went farm to farm within Delaware
– 38% went to non-Delaware farms
– 31% went into alternative uses
– In FY 2012, 87,000 tons of manure transported in
Delaware

Other Alternative Uses
• Burning to produce electricity
• Anaerobic digestion to produce electricity or
gas
• Farm Pilot Project Coordination, Inc.
So, how are we doing in Maryland?
