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

Manure Spreading Advisories

For producers, Manure Spreading Advisories provide guidance about the ‘right time’ for responsible manure spreading in the south coast of British Columbia.

For the public, Frequently Asked Questions about manure spreading are answered.

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.’

Interactive Tools

Interactive tools are being developed to make information more accessible and user-friendly. This information is about managing soils, crops, and nutrient sources including manure.

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.

Nutrient Management Reference Guide

The Nutrient Management Reference Guide is for planners and agricultural producers in British Columbia who would like to do a Nutrient Management Plan for their farm.

Technical Reports

Technical reports offer detailed, research-based, information on specific topics regarding nutrient management challenges and opportunities in British Columbia.
