Kieserite granular|Rongqing Chemical, also commonly known as magnesium sulfate monohydrate, is a compound magnesium fertilizer that combines two important secondary nutrients, sulfur and magnesium.
Kieserite granular, also known as magnesium sulfate monohydrate, is a compound magnesium fertilizer that combines two important secondary nutrients, sulfur and magnesium. Magnesium is one of the essential nutrients for crop growth and a component of chlorophyll in crops. Kieserite granular can promote the synthesis of plant substances, activate enzymes, and stimulate root growth, thereby increasing crop yields and improving crop quality.

Kieserite granular can be used either alone or as an ingredient in mixed fertilizers or compound fertilizers. Its granules can also serve as soil conditioners for acidic soils. When applied to various horticultural and large-scale crops, the incomplete water solubility of Kieserite granular allows it to slowly dissolve in water, achieving a perfect effect of slow-release fertilization.

–Kieserite (MgSO4.H2O) is widely used in agriculture and forestry as one of the best supplements of Magnesium and Sulphur for magnesium insufficient crops and soils.
–Both Mg and S influence a wide range of metabolic processe
–Widely used in fruit, vegetable and especially for palm oil plantation.It’s essential in order to achieve high yields and good quality crops.
–Kieserite is absorbed easily and does not destroy the PH value of the soil.
–It can be used alone or mixed in other fertilisers or in compound NPK’s.
1.The granular is main material for blending fertilizer.
2.Low Chloride, low heavy metal, low free acid,
3.Slow release with uncompletely water solubility,
4. No caking with good fluidity,
5. Weak alkalinity
