Ammonium sulfate, cryst.

Nitrogen and Sulfur Synergism for Intensive Growth

Ammonium sulfate in crystalline form is more than just a nitrogen source; it is a precision tool for optimizing crop quality. Unlike ammonium nitrate or urea, this fertilizer provides sulfur in a sulfate form that plants can absorb immediately. Sulfur is essential for protein synthesis, making this fertilizer a priority for oilseeds and cruciferous crops.

Why choose crystalline Ammonium Sulfate?

• Performance on alkaline soils: Ideal for alkaline and carbonate soils, as it slightly acidifies the root zone, significantly improving the uptake of essential microelements.
• Extended availability: Nitrogen in the ammonium form binds to the soil adsorption complex, reducing losses due to leaching during heavy rainfall.
• Superior crop quality: Crops like rapeseed, flax, and cabbage rely heavily on sulfur. Regular application directly correlates with higher oil content in seeds and better protein quality in cereals.

Application and Efficiency

Applied as a base fertilizer at rates of 100–200 kg/ha, ammonium sulfate ensures a vigorous start for the crop. The crystalline structure is highly practical, ensuring uniform spreading and preventing the dust issues common with powders. It is highly recommended for winter crops (barley, rapeseed) during early spring regrowth to provide the nitrogen 'fuel' needed for rapid vegetative development.

The competitive edge of this fertilizer lies in its comprehensive effect on plant metabolism. While standard nitrogen simply drives biomass, the sulfur component ensures that the weight gain is accompanied by high nutritional value. This makes it the optimal choice for professional farms aiming for export-grade quality in oilseeds and grains.
