IL producers justifiably proud of their food systems
Livestock systems
Shabonna, IL ca. 1960
…ca. 2000
1960’s: Slotted flooring
Livestock + crops= good combination
“Sustainable Ag”
Nutrient management incentive recognized by industry
U of I Extension tours early
liquid manure systems, Illinois,
early 1960’s
Before flotation tires
and GPS…
Manure storage size reflects industry consolidation
Manure and wastewater application systems
How livestock industry uses nutrient management planning to reduce
nonpoint source pollution 0 What NMP can do for an operation
0 What NMP can do for the environment
What does a Nutrient Management Plan do for a livestock operation?
0 Recognizes and improves fertilizer use of principle plant nutrients and micronutrients in manure
0 Protects environment, especially water quality
0 Provides a structured base for discussion of management practices between the producer and other interested parties
What does a nutrient management plan for livestock production look like?

Plan, Performance, and Protection
0 The Plan tells about your operation and what you expect to do
0 The Performance is the record of what you did. This includes annual updates.

Plan, Performance, and Protection
0 The Protection is thinking through how to respond to emergencies
0 All acceptable manure nutrient management plans have these features! (And the CNMP† has others).

Nutrient management planning: Why, who cares, etc.
0 State and national regulations
0 Federal Clean Water Act, Federal EPA and CAFO regulation
0 IL EPA Title 35 Subtitle E, Agriculture Related Pollution, Parts 501, 502, 506, 560, 570, & 580
0 Livestock Management Facilities Act and Rules Waste Management Plan section 8 IAC Code 900
0 Federal incentive program requirement
0 Environmental Quality Incentives Program
Nutrient management planning: Why, who cares, etc.
0 Facility size based
0 Generally, all “large† operations” are required to have a formal nutrient management plan
0 UI Extension advises all livestock operations to make and maintain a plan, with the same basic structure as used for “large”
†There are at least three different agency definitions of “large” livestock operations in Illinois.
Nutrient management planning: Why, who cares, etc.
0 Ag stormwater exemption requirement
0 Protection is provided for those operating under a recognized nutrient management plan
Nutrient management planning: Why, who cares, etc.
0 Federal EPA CAFO Rules CFR 122.23 e). (1) For unpermitted Large CAFOs, a precipitation-related discharge of manure, litter, or process wastewater from land areas under the control of a CAFO shall be considered an agricultural stormwater discharge only where the manure, litter, or process wastewater has been land applied in accordance with site-specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients in the manure, litter, or process wastewater, as specified in § 122.42(e)(1)(vi) through (ix).
Nutrient management planning: Why, who cares, etc.
0 (2) Unpermitted Large CAFOs must maintain documentation specified in § 122.42(e)(1)(ix) either on site or at a nearby office, or otherwise make such documentation readily available to the Director or Regional Administrator upon request.
Regulatory and practical arenas: Disparity?
0 Setbacks and how to protect them
0 Conflict between application rate constraints:
0 nitrogen and phosphorus “agronomic rates”
0 conservation compliance
Regulatory and practical arenas: Disparity?
0 Manure application timing and methods, and being a good neighbor (contrast with commercial fertilizer applications)

Quick quiz: Nutrient management example
0 Situation:
0 Beef producer with a slotted floor barn, 1200 head capacity, wants to apply liquid manure product to cropland
0 Time: October
0 Place: field that will have corn planted next spring, 200 bu/ac average
0 Regulation: apply at the “agronomic rate”, nitrogen or phosphorus based
0 What rate of manure application does he use?
What the livestock producer community would like to see happen
0 Evolution in regulatory constraints 0 Performance based rather than overly
prescriptive 0 Example: extra setback rules
0 Help with research and technology 0 Ag research is pathetically under-funded by
Federal partners 0 On-the-go manure nutrient
sensing>automatic application rate adjustment
0 Regulatory parity between principally livestock producing and strictly crop producing operations
Summary 0 Livestock industry has the will and incentive to use
nutrient management planning for water quality protection
0 Regulatory framework holds livestock producers to a different standard than other ag sectors (crops)
0 Technological challenges are gradually being overcome
0 Ag research $$ needed
