📈 Boost Winter Wheat Yield Potential at Flag Leaf – Here’s How

As we reach the flag leaf stage in winter wheat across much of
the UK, growers face a narrow but powerful opportunity to protect and maximise yield. This phase is often underestimated—yet it’s one of the most influential stages for grain production.
If you’re aiming to push your wheat performance this season, now is the ideal time to apply Complex Foli-N from SFS.
Here’s why.
🌾 Why the Flag Leaf Stage is So Important
The flag leaf is the final main leaf to emerge before the wheat ear and plays a massive role in yield development. It’s responsible for up to 45% of final grain fill, making it the workhorse of your crop’s photosynthetic activity through flowering and into grain fill.
Unfortunately, many crops are already under pressure due to dry soils and limited nutrient uptake through the roots. This puts the flag leaf at risk of stress, senescence, and underperformance—just when it should be powering yield.
Foliar nutrition bypasses the root zone and delivers essential nutrients straight to the flag leaf—exactly where and when they’re needed most. But Complex Foli-N goes a step further.
This isn’t just a shot of nitrogen. It’s a complete foliar tool:
Delivers Immediate Nitrogen
Supports flag leaf growth and chlorophyll production when root uptake is limited by dry soils.
Extends Green Leaf Area
Keeps the canopy greener for longer—essential for sustaining photosynthesis through grain fill.
Boosts Nutrient Efficiency
Helps the crop make better use of applied nitrogen and trace elements at a critical time.
Enhances Stress Tolerance
Supports resilience to heat and drought stress by stabilising plant metabolism.
Improves Grain Set and Quality
Strengthens flowering, pollen viability, and kernel development—directly supporting yield and protein.
Supports Overall Crop Health
Promotes better structure, stronger physiological function, and increased immunity.
Easy to Use
Tank-mix compatible with fungicides—no need for a separate pass.
