According to Dr. Stanley Barber, Purdue Univ., "There is no research justification for the added expense of obtaining a definite Ca:Mg ratio in the soil. Research indicates that plant yield or quality is not appreciably affected over a wide range of Ca:Mg ratios in the soil."
Gypsum is recommended for two primary purposes. They are - To remove excess sodium (Na)
- To build soil calcium (Ca) levels when a pH change is not desired
