Manure Injection Waste Utilization (Code 590)


Manure Injection MachineThe Natural Resources Conservation Service is offering conservation assistance by encouraging California growers to use new and innovative agricultural emission reduction practices and technologies that provide significant environmental benefits to our natural resources.

The protection of air quality by reducing nitrogen emissions (ammonia, oxides of nitrogen) and the formation of atmospheric particulates can be achieved through effective land application of manure injection into the soil. An enhanced nutrient management system may include activities such as tissue tests, split applications, slow release nutrients, nitrogen inhibitors and NRCS-approved nutrient risk assessments in accordance with the practice standard. Manure injection may assist with adjusting the source, timing, amount, and placement of nutrients applied to minimize denitrification or ammonia volitization.

This practice incentivizes the adoption of managing the amount (rate), source, placement (method of application) and timing of plant nutrients and soil amendments. Funding priorities are based on a screening and ranking process that considers the benefits of planned conservation practices, as identified by local, state and national priorities within nationally designated air quality non-attainment areas in California.

Practice Standard 590 - Nutrient Management Program Specifics-Enhanced

California growers must meet EQIP eligibility requirements to qualify for payments.

  • The land enrolled under the contract must be owned or in long-term control of the producer and must be currently cropped.
  • Manure injection is part of a nutrient management strategy. Please refer to NRCS Practice Standard 590-Nutrient Management for more information.
  • Recommend that diesel-powered equipment utilize cleaner, less polluting Tier-certified diesel engines.
  • Under a three-year contract, payments are made in the first and second years of the contract.

Odor management is currently not a purpose for the California Air Quality Initiative.
