Crop Intelligence Agronomy Insights
Crop Intelligence INSIGHTS
- Window of Opportunity: 5 leaf – bolting/early flower:
- Tissue test to evaluate crop health and identify potential nutrient deficiencies.
- Top dress nutrient applications to capture additional yield potential beyond your spring fertility package.
- Time applications with forecasted rain events whenever possible in order to move nutrients into the root zone and reduce volatilization losses.
- Plan fungicide applications to protect increased yield potential.
- Talk to your trusted advisor/agronomist for the solution that best suits your circumstances.
Yield responses are greatest early, diminishing as growth proceeds. The demand for NPKS (Ca, Mg, Cl, micros) is massive during this period
- N, S, Cl, B are soil mobile with many application options.
- P, K, Mg, Ca and other micros are economically/logistically limited to foliar approaches.

- Window of Opportunity: 5 leaf – early boot stage is a crucial time for decision making and ACTION.
- Tissue test to evaluate crop health.
- Top dress nutrient applications for yield and quality.
- earlier = greater impact to yield, later = greater impact to quality
- Fungicide applications should be top of mind to protect yield potential.
- Consider crop condition and stage, yield potential, field history, and environmental conditions.
- Talk to your trusted advisor/agronomist for the solutions that best suit your circumstances.

Tissue Test Stages - physiologically the ‘same’ for all crops
Using cereal for discussion
- 5 leaf stage (just before elongation) and Flag leaf.
- These stages provide the macronutrient yield response boundaries.
- The micronutrient window is wider but managed much differently.
Within the boundaries
- Yield response diminishes with time - Macronutrient Response Triangle.
- Quality response continues much longer.
