What Is a NASM Plan?
A NASM (Non-Agricultural Source Material) Plan is required when materials such as biosolids, food processing waste, or other non-agricultural byproducts are applied to agricultural land. These materials are highly regulated under Ontario's Nutrient Management Act.
Highly Regulated
NASM plans involve strict regulatory oversight. Proper planning and documentation are essential to remain compliant.
Materials That Require a NASM Plan

Frequently Asked Questions
Do I need an NMS to build a barn in Ontario? In most cases, yes — if you are increasing livestock or nutrient storage capacity, you will likely need a Nutrient Management Strategy (NMS) before construction can begin.
What are nutrient units? A nutrient unit is a measurement used under Ontario's Nutrient Management Act to determine the regulatory requirements for your farm. It's based on the type and number of livestock you have.
When do I need both an NMS and an NMP? Typically when your farm operation exceeds 300 nutrient units, you'll need both a Nutrient Management Strategy (NMS) for storage and expansion, and a Nutrient Management Plan (NMP) for land application of nutrients.
How long does approval take? Approval timelines vary depending on the complexity of your operation. Most plans take several weeks from farm visit to final approval. Starting early is critical — delays can cost you a full growing season.
