1. How can I apply Sulfate of Potash Magnesia?

We recommend applying our Sulfate of Potash product by broadcasting/spreading it on the soil and working it in. It is also recommended to water it thoroughly after each application.

Note: K-Mag is not 100% water soluble and cannot be applied as a foliar application or dissolved in water.

 

2. Is Greenway Biotech K-Mag same as Langbeinite?

Unfortunately, we are not familiar with Langbeinite. However, our K-Mag contains Potassium, Sulfur, and Magnesium.
