The product
Two essential nutrients, working together.
Ammonium sulfate delivers nitrogen and sulfur, with a typical composition of 21% N and 24% S. These nutrients support protein synthesis, chlorophyll production and nutrient uptake. Poleum supplies granular, crystalline and compact forms for direct application, blending, fertigation and soil rehabilitation programs.
The right fit
Particularly relevant for sulfur-demanding crops and soils depleted by intensive cultivation or low organic matter.
Applications & benefits
Purpose in every application.
Dual Nutrient Value
Supplies both N and S in plant-available forms
Sulfur Supplementation
Corrects sulfur deficiency common in intensively farmed soils
Stable & Blendable
Compatible with other fertilizers for custom formulations
Improved Nutrient Uptake
Enhances root absorption of phosphorus and micronutrients
Yield Support
Increases protein levels in grains and boosts oil content in oilseeds
