Nutrient Management

Nutrient management is about supplying crops with the amount, form, placement, and timing of nutrients (whether as manure, commercial fertilizer, or other nutrient sources) to optimize crop growth and minimize environmental risks to water quality and air quality.

Nutrient management adopts the principles of the 4 R's :

Right rate
Right time
Right place
Right source

Deciding What to Apply

Deciding what to apply to agricultural fields begins with knowing what resources you have in the form of soils, crops and manures. Then nutrient management decisions can be made, particularly about the ‘right’ nutrient source, the ‘right’ rate, and the ‘right place.’

Air Quality and Nutrient Management

Nutrient management is linked to regional air quality: dust and odour concerns arise during nutrient application, and ammonia-nitrogen can be a precursor of fine particulates (PM2.5) in the air.
