What is Nutrient Management?
Plant nutrients, which are contained in both manure and
chemical fertilizers, are essential to a farm operation. When
applied in proper quantities and at appropriate times, the
nutrients will aid in achieving optimum crop yields. However,
improper use of nutrients can lead to soil-nutrient and
feed-ration imbalances and can cause water quality problems both
locally and downstream. The objective of nutrient management is
to use nutrients (mainly nitrogen, phosphorus and potassium)
wisely for optimum economic benefit, while minimizing impact on

The Nutrient Management Act
The Ontario Nutrient Management Act passed on June 27, 2002.
The Nutrient Management Act provides farmers with the guidelines
to regulate nutrients on all Ontario farms regardless the size,
type of operation or location within the province. The stated
purpose of the Act is "to provide for the management of
materials containing nutrients in ways that will enhance
protection of the natural environment and provide a sustainable
future for agricultural operations and rural development."
Operators of every new and every large livestock farm in
Ontario will be developing a nutrient management strategy (NMS),
a nutrient management plan (NMP), or both. In the coming years,
having and using these documents will become standard operating
As of September 30, 2003 all new livestock farms,
larger than five nutrient units were subject to the Nutrient
Management Act (2002) regulation. As well beginning on
September 30, 2003 all expanding farms with 300 nutrient units
or more were also subject to the regulation. In addition,
certain categories of farms will be required to have provincial
approval of their nutrient management plans/strategies. In 2005,
all existing operations equal to or larger than 300 nutrient
units will be subject to the regulation.
In 2008 other
types of agricultural operations may become subject to the
regulation. The OMAF websites states that implementation of the
regulation at that time will be subject to available funding to
assist farmers with complying with the regulation.
