Lime and Gypsum FAQ #1
What is the difference between lime and gypsum in agricultural applications?
Lime (calcium carbonate) is primarily used to raise soil pH in acidic soils, while gypsum (calcium sulfate) improves soil structure without altering pH. Lime provides calcium and reduces acidity, whereas gypsum provides calcium and sulfur while helping break up clay soils. Both products complement each other but serve different primary purposes in soil management.
Lime and Gypsum FAQ #2
How often should I apply lime and gypsum to my fields?
Lime application frequency depends on soil test results and typically ranges from every 3-5 years for maintenance. Gypsum can be applied annually or biennially depending on soil conditions, especially in heavy clay soils or areas with sodium issues. Always begin with a soil test to determine exact needs, as over-application can lead to nutrient imbalances.
Lime and Gypsum FAQ #3
Can lime and gypsum be applied together?
Yes, lime and gypsum can be applied together when both soil pH adjustment and structure improvement are needed. They don't chemically interfere with each other. However, it's recommended to conduct a soil test first, as some soils may require one product more than the other. The application ratio should be based on soil test recommendations for optimal results.

Application Guidelines
- Conduct a comprehensive soil test before application
- Calculate required application rates based on test results
- Apply during dry conditions for best results
- Incorporate into soil when possible (especially for lime)
- Water lightly after application if no rainfall expected
- Re-test soil after 6-12 months to evaluate effectiveness
