Poultry Litter Land Application Worksheet Tool

The new Poultry Litter Land Application Worksheet Tool allows Tennessee poultry producers who do not have a Concentrated Animal Feeding Operation (CAFO) permit to set agronomic litter land application rates for their specific farms and fields.

The tool is based on the UT Extension’s publication, Litter Land Application Management, and the calculations and recommendations presented therein.


The Worksheet Tool is designed to meet the following objectives:

  • Maximize Litter Value. Agricultural producers need to control production costs. The Worksheet Tool maximizes the value of litter nutrients and minimizes costs for commercial fertilizers without sacrificing economic crop returns.
  • Environmental Regulations. Stormwater runoff that contains land-applied litter, or excess nutrients from land-applied litter, can be considered an illegal discharge by the Environmental Protection Agency (EPA). To avoid being considered an illegal discharge, litter must be “land applied in accordance with site-specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients” (40 C.F.R. § 122.23(e)(1)). This regulatory requirement applies to poultry farms that confine 82,000+ laying hens or 125,000+ of any other type of chicken (40 C.F.R. §122.23(b)(4)). This Worksheet Tool provides poultry producers with a field-specific nutrient management system for agricultural utilization of litter nutrients, as well as a required recordkeeping form (40 C.F.R. §122.23(e)(2)).
    • NOTE: This Worksheet should NOT be used by poultry farms required to have a CAFO permit or that voluntarily choose to operate with a CAFO permit. Permitted farms MUST follow the Nutrient Management Plan (NMP) approved with their permit.
  • Minimize the Negative Environmental Impact of Land Applied Litter. Applying more nutrients than your crop demands can enrich surface waters with nutrients that degrade both local and distant receiving waters. The Worksheet Tool sets litter application rates that minimize the possible negative environmental impacts of litter nutrients.
