Environmental Sustainable

1
Environmental Sustainable

• Environmentally friendly farms
• One of the attributes that customers prefer
• Beelers have environmental guidelines
• Nimans homepage
• Environmentally Sound
• and sustains the land and community for future
  generations.

2
Sustains the land for future generations

• Set of standards that are used to measure
  environmental sustainability
• Generally Accepted Agriculture Management
  Practices
• Michigan Environmental Assurance Program
• Progressive planning
• Comprehensive Nutrient Management Plan
• Verified by DEQ or MAEAP

3
Environmental Sustainable

• Michigan law provides Right to Farm protection
• Protection is contingent on following GAAMPs
• Manure Management and Utilization
• Siting New and Expanding Lvstk Facilities
• Animal Care

4
Standards

• GAAMPs for Manure Management and Utilization
• Meeting Right to Farm guidelines
• Assure customers that your farm is meeting
  environmentally standards
• But
• Is not third party verified

5
Important GAAMP practices

• Soil test fields every three years
• Test manure annually
• Estimate manure nutrient accumulation and crop
  utilization
• Prevent manure runoff
• Protect lakes, streams,
• ditches and tile inlets
• Odor management

6
Soil test fields every three years

• Manure application rate is dependent on P level
• Ensures that manure nutrient production is in
  balance with crop utilization
• Protects states waters from nutrient runoff

Estimate manure nutrient accumulation

• Book values
• MidWest Plan Service Manure Characteristics
• Manure samples and accumulation records
• (N P K / 1,000 gal.) x (application records)
• Mass balance for P

9
Using book values

• 100 sows in pasture system
• Farrow 2 times
• Average 8 pigs per litter
• weaned

P removal by crops

• Average 38 per acre
• 222 acres of crops to utilize 8,454 P2O5

P removal by crops

• Soil test levels do not respond on a 1 to 1 basis
  with P crop removal
• On average MI soils, 10 P2O5 crop removal will
  lower soil P level 1 1

Prevent manure runoff

• Runoff control is required to prevent manure from
  leaving your property
• Storage basins and infiltration areas must be
  designed to retain 25 yr 24 hr event
• Design facilities to MWPS or NRCS-FTOG
  specifications
• Do not spread within 150 feet of open water

14
Prevent manure runoff

• Acceptable practices
• Grass waterways, infiltration areas, buffers

15
Odor management

• Site facilities to minimize effects on neighbors
• GAAMPs for Site Selection and Odor Control
• Practices to reduce odor during application
• Avoid spreading when wind is blowing towards
  neighbors
• Avoid spreading on weekends and holidays
• Spread in AM when air is warming and rising
• Use current weather data to your advantage
• Incorporate manure applications within 48 hrs

16
Documenting practices

• Manure Management Systems Plan (MMSP)
• Establishes that you have addressed all areas of
  concern
• Provides basic information to move into more
  detailed
• Meets GAAMP planning requirements

17
Manure Management Systems Plan

• Production
• Estimate the manure nutrients accumulated on your
  farm
• Collection
• Storage
• Treatment
• Transfer
• Utilization
• Record keeping
• Odor management
