Most of our customers have been switched from traditional lime applications to gypsum applications. Why?
- The main benefit we were after in applying lime was calcium. Gypsum is high in calcium plus sulfur.
- Lime applications will raise the ph in your soil. Gypsum will not. Most soil tests we have done in the West Michigan area show ph levels being high enough.
- Sulfur is a nutrient that is on the low side in the majority of soil tests we have done.
- We are getting a color response from gypsum where that would not happen with lime. At least not immediately.
- Gypsum is a great soil conditioner for heavy soils.
So where does lime fit in?
Lime is still a product we will use. Where a soil test has been done or on a site where we know the ph is going to be too low we will use lime. Indications that the soil is acidic (low pH) would be...
- Sandy Soil
- Moss growing in full sun areas
- The weed "red sorrel" is an indicator of low pH
- Subdivisions that were previously blueberry fields or are near them may have a low pH level.
