Natural Magnesium Sulfate, Kieserite Earth Mineral

Magnesium sulfate mineral, also called kieserite, is a natural form of earth mineral that contains a high concentration of magnesium and sulfur. 

Kieserite can be directly applied to mix with soil to improve the magnesium and sulfur levels in soil.

Soils with low magnesium content cannot ensure high - quality output. In particular, sandy or low - pH soils tend to have a magnesium deficiency, 

and it is necessary to increase the magnesium content by applying kieserite.

Soil that grows high - frequency harvest plants tends to have low magnesium content because each harvest will remove magnesium.

Directions For Use

It is recommended to conduct a soil test to understand the soil magnesium level and then develop application plans.

Direct Application.

When applying Kieserite micronized powder 2500 mesh to mix with soil, it is recommended to apply 200 to 300 kilograms per hectare.

Soil Irrigation

Micronized kieserite powder with a mesh size of 2500 is fine enough to pass through most nozzle holes. 

Thanks to its large surface area, it can also maximize the application efficiency.

Dilute it with water at a ratio of 1:500 and stir well to prevent precipitation in your irrigation systems.
