Sulfat magniiu, gr. ta kr.p., (MgO - 16-23%, SO3 - 30-46%)

Why professionals rely on Alwernia

In the field, when you're managing crops like winter rapeseed, corn, or potatoes, magnesium and sulfur aren't just additives—they are essential for survival. We’ve been using the magnesium sulfate from «Zaklady Chemiczne Alwernia S.A.» for years. Whether we are dealing with crystalline or granular forms, the performance is consistent. It is the go-to solution for foliar feeding when crops are struggling with nutrient deficiencies or post-stress recovery.

Handling and Application Experience

From an operator's perspective, the biggest win is solubility. The crystalline form dissolves perfectly in the spray tank, which means I don't waste time cleaning clogged nozzles during the busy spraying season. When applied, the plant response is visible within days: the leaves regain that deep, healthy green color, signaling that photosynthesis is back in full swing. Because sulfur (SO3 30-46%) is highly bioavailable here, it makes nitrogen uptake significantly more efficient.

Field Tips

• Tank Mixing: The product is highly compatible with most pesticides, but always check the label/compatibility before batch mixing.
• Convenience: The granules are easy to handle, produce minimal dust, and store well without clumping if kept in a dry place.
• Results: It’s an essential tool for maximizing yield, especially on light soils where magnesium is naturally leached out.

Choosing this product from the Polish manufacturer «Alwernia» gives me peace of mind. It’s a straightforward, high-quality input that helps crops hit their genetic yield potential without unnecessary complications.
