Crop Nutrient Demand by Stage
An interactive reference showing when each crop pulls hardest on which nutrient — and where the critical windows are. Click any stage to see what's happening biologically and what's at risk.

How to read this tool
Each row is a nutrient
Colours show demand intensity across growth stages — deeper green means higher demand. Rust cells are critical windows where deficiency causes irrecoverable yield loss.

Click any column to see what's happening biologically, what to scout for, and which nutrients are at peak or critical demand that stage.
Use it with the pH chart
The demand chart tells you when a nutrient matters most. The pH & nutrient chart tells you whether it's available in your soil. Pair them.
Important — this tool is for general information only
Demand curves for the four anchor crops are based on published provincial and crop commission references — including the Canola Council of Canada, SaskPulse, Alberta Agriculture, and the Western Fertilizer Handbook. This tool is provided for educational and general informational purposes only. Intensity values represent relative demand patterns across stages — they are not precise lbs/ac removal values or fertilizer recommendations.
Do not make fertility, input, or management decisions based solely on this tool. Real nutrient demand varies significantly with variety, weather, soil type, yield target, and biological conditions specific to your operation. What's shown here is a general guide — your fields may behave differently.
