● Fertilizer Grade Products

Magnesium nutrition and the application of magnesium fertilizers have long been key concerns in international agronomy and soil & fertilizer science.

According to the *Nutrient Management Handbook* of the International Fertilizer Industry Association (IFA), magnesium is one of the essential nutrients for crop growth and a key component of chlorophyll in crops. It promotes the synthesis of plant substances, activates enzymes, stimulates root growth, increases crop yield, and improves crop quality. Magnesium fertilizers can be used alone or as components of compound fertilizers. Magnesium-containing fertilizers can also be used as acidic soil conditioners.

Features of granular products: low chlorine, low heavy metals, low free acid, free of chemical organic substances, good water solubility, non-caking, dust-free, good hardness, weakly alkaline;

Features of powdered products: low chlorine, low heavy metals, low free acid, free of chemical organic substances, good water solubility, non-caking, good fluidity, weakly alkaline.

● Fertilizer containing magnesium and macro- and micro-elements

Containing magnesium and multiple essential trace elements, this fertilizer takes magnesium as its main nutritional core. It combines various plant-essential trace elements to synergistically provide growth nutrition for crops, while effectively supplementing the missing nutrients in the soil, achieving bidirectional nutritional supply between crops and soil.
