Margin Under Pressure. Efficiency Becomes the Lever.
The Role of Plant Available Silicon (PAS)
Why nutrient conversion — not input volume — is becoming the critical yield lever in modern cropping systems
The Efficiency Challenge in Modern Cropping
Across modern cropping systems, margin pressure is no longer cyclical — it is structural.
Nutrients may be present in the soil. But if they are not effectively converted into plant growth, yield potential is left unrealised.
The question is no longer:
“How much fertiliser do I apply?”
It is:
“How efficiently can the plant convert available nutrients into yield?”

Not All Silicon Behaves the Same in Soil
Silicon is abundant in soil — but availability, not abundance, determines plant response.
Only soluble silicon (Plant Available Silicon – PAS) can be absorbed by plants and contribute to structural strength, stress tolerance, and nutrient efficiency.
