Application
Agricultural Grade-Sulfur and magnesium can provide rich nutrients for crops that it contributes to crop growth and increase the output, it also helps to loosen the soil and improve soil quality.Magnesium sulfate promotes photosynthesis in plants and increases the synthesis of fats and proteins.It can be used as base fertilizer and BB fertilizer.
Feed Grade-Magnesium is usually Fertilization among the early spring and the end of the year, until the grass can provide adequate magnesium ,it can also added in the feed and drinking water to meet growing demand of dairy cow's sebum, in order to improve the quality and quantity of milk cows.
