Application
Agriculture & Horticulture
Many growers and fertilizer distributors are troubled by insufficient magnesium supplement, poor soil acidification, low absorption of medium‑trace elements, and fertilizers with narrow crop adaptability. These problems will result in slow crop growth, poor fruit setting, reduced output and wasted fertilizer input.
Our 99% magnesium sulfate works perfectly as magnesium fertilizer, water‑soluble fertilizer and nutrient solution for soilless culture. It can condition acidic soil and boost the availability of medium and trace elements for crops, which contributes to a remarkable increase in crop yield. It is widely suitable for a full range of crops such as vegetables, fruit trees, flowers, tobacco, rice and other varieties, helping you cut fertilizer waste and maximize planting returns.
Chemical & Industrial Field
Many industrial manufacturers suffer from fabric color fading, poor leather texture, low‑whiteness paper and out‑of‑control water hardness, causing defective products and higher production costs.
Our magnesium sulfate is widely used in printing and dyeing, papermaking, leather making and water‑treatment industries. It can fix fabric colors, optimize leather softness, improve paper whiteness and regulate water hardness, supporting consistent production quality.
