Custom Manure Applicators

Introduction to the Custom Applicator Certification Program:

As part of Act 64 signed into law of June 2015, the Vermont Agency of Agriculture, Food & Markets (VAAFM) was directed to require training and certification of custom manure applicators that operate within the State of Vermont.  The Custom Applicator Certification Program was formalized with the passing of the Required Agricultural Practices (RAPs) in December 2016, which include training and certification requirements for custom applicators that operate within the State of Vermont.

Custom Applicator Definition:

A custom applicator is a person who is engaged in the business of applying manure or nutrients to land and who charges or collects other consideration for the service. All owner/operators or full-time custom applicators must be certified with VAAFM to operate within the state of Vermont. Seasonal, part time, or other employees of custom applicators must receive training on the Required Agricultural Practices (RAPs) and management practices to reduce risk of runoff when spreading manure.

The RAP Rule requires Custom Applicators:
  • Be certified by VAAFM, certification lasts for 5 years but must be renewed annually
  • Receive 8 hours of training each five-year period of certification
  • Demonstrate knowledge of RAPs and all other applicable agricultural rules
  • Train all their seasonal, part time, or other employees in methods or techniques to minimize runoff to surface water
  • Maintain records of the amount of manure or agricultural waste applied by farm and field

Custom applicators certified by VAAFM are required to receive 8 hours of training every five-year period of certification.  Seasonal, part time, and other types of employees are also required to receive training that address application methods to minimize runoff and identification of weather or soil conditions that increase risk of runoff.
