What are the 4R Principles?

What are the 4R Principles?


Right Source Right Time
  • Select the correct source of nutrient for your soil ensuring a balance supply of essential plant nutrients including granular or liquid fertilizers or manures
  • Avoid fertilizer or manure application on snow or frozen soil.s
  • Carry out nutrient management planning on an annual basis.
Right Rate Right Place
  • Consider the availability of nutrients from all sources (eg. Livestock manures, commercial fertilizers and atmospheric nitrogen fixed by legumes).
  • Perform annual soil testing.
  • Apply nutrients to meet crop requirements while accounting for the nutrients already in the soil.
  • Calibrate application equipment to deliver target rates.
  • Respect recommendated setback distances for nutrient application near waterways.
  • Place nutrients below the soil surface where they can be taken up by growing roots when needed.



Nutrient Stewardship

What is the 4R Nutrient Stewardship?

Fertilizer is an important input for farmers providing nutrients to plants that are not readily available in the soil, helping farmers to foster plant growth and increase yields
4R Nutrient  Stewardship (Right Source at the Right Rate and the Right Time in the Right place) lets the world know when food has been sustainably grown.
4R Nutrient Stewardship balances farmer, industry and government goals to improve on-farm economics, crop productivity and fertilizer efficiency while benefiting the environment
Sustainable farming is the future. Start implementing 4R nutrient Stewardship, and record your progress online to demonstrate how we are leaders in sustainable agriculture.
Benefits of Using the 4R Nutrient Stewardship



Benefits of Using the 4R Nutrient Stewardship


Improve Agricultural Productivity Minimize Impact to the Environment
  • Optimizing nutrient managment is simply good business in dealing with fluctuations in prices of fertilizer and other inputs, as well as in process of crops sold.
  • Higher crop yields are well documented with better crop and soil management
  • Improving fertilizer efficiency increases the quantity prodcued per acre for each unit of nutrient applied, without sacrificing yield potential
  • Adopting nutrient stewardship contributes to the preservation of natural exosystems by growing more on less land.
  • Retaining nutrients within a field's boundaries and in the crop rooting zone greatly reduces the amount that i snot utilized by plants and thereby escapes into the environement as pollution.
