What is nutrient management?

Nutrient management is an essential step in maintaining soil health and optimizing crop yield and quality. Nutrient management involves applying the right type of nutrient sources, such as manure, fertilizer or compost in the right amount, in the right place and at the right time.

Soil sampling and testing is often a first step in nutrient management and a proactive approach to monitor and maintain soil health, informing farmers how much manure (or alternative nutrient) to apply, and where. A major reason for soil testing is to evaluate soil fertility, the ability of the soil to supply crops with nutrients.

Understanding soil test results can guide decisions and help to:

  • Know what nutrients your crops will require
  • Avoid over-application of nutrients and unnecessary costs
  • Prevent water contamination and greenhouse gas emissions
  • Maintain optimum pH, micronutrients in your soil
