Additional Guidelines and Recommendations

  • Raw manure is used to build fertility before planting:
    • It needs to be incorporated into the soil.
    • The field or garden area is not planted until two weeks after manure application.
  • Interval between raw manure application and harvesting
    • 90 days if edible portion of crop does not come into contact with soil.
    • 120 days if edible portion is in contact with soil (e.g. tomatoes, peppers, etc.).
  • Develop strategies to discourage trespassing by wild animals (inadvertent fertilization/contamination):
    • Strategies may include fencing, netting, motion detectors connected to sprinklers or lights, etc.
    • Do not harvest produce from areas with animal manure present.
  • Keep pets and other domestic animals out of crop areas to prevent contamination from feces.
  • Proper composting of manure will kill pathogens:
    • Compost much reach an internal temperature of 131°-170°F.
    • Temperature must be maintained for the appropriate length of time.
