When Is an NMP Required?
A Nutrient Management Plan (NMP) is required under Ontario Regulation 267/03 when a farm operation meets certain size thresholds related to nutrient generation and land application. The NMP focuses specifically on how nutrients are applied to agricultural land.
You Likely Need an NMP If:
Your farm operation exceeds 300 nutrient units
You are applying nutrients to land from a large operation
You are receiving nutrients from off-farm sources for land application
Your operation requires both an NMS and NMP under O. Reg. 267/03
You Probably Don't Need an NMP If:
Your operation is under 300 nutrient units and not expanding
You don't apply manure or other nutrients to agricultural land
You only need a Nutrient Management Strategy (NMS) for barn construction
What Does an NMP Cover?
An NMP covers the land application side of nutrient management, including soil testing, application rates, timing restrictions, setbacks from watercourses, and record-keeping requirements.

Check whether a proposed barn location may be constrained by MDS, setbacks, or nearby land uses.
Calculate Nutrient Units
Estimate livestock nutrient units to help determine whether NMS or NMP requirements may be triggered.
