Non-Agricultural Source Materials (NASM)
NASM is treated and recycled material from non-agricultural sources like leaf and yard waste, fruit and vegetable peels, food processing waste, pulp and paper biosolids and sewage biosolids. NASM provides organic matter that can help maintain soil productivity and reduce soil erosion. NASM has been applied to Ontario farmland for more than 30 years. NASM application, in accordance with Ontario's rules and guidelines, has provided valuable nutrients to soil and crops while protecting public health and the environment.
Since 2011, the rules and guidelines for applying non-agricultural source materials (NASM) to farmland have been part of Ontario Regulation 267/03.
The rules and guidelines for the land application of NASM were developed by scientists and agricultural specialists from the Ministry of the Environment and Climate Change and the Ministry of Agriculture, Food and Rural Affairs (OMAFRA), with extensive consultation of industry and environmental organizations, scientists and various other stakeholders.
