For home gardeners, the recommended amount of gypsum to apply is 40 pounds per 1000 square feet.
Applying gypsum (calcium sulfate) can help improve soil structure, especially in compacted or sodic (high sodium) soils. The correct application rate is important for achieving the desired results without over-applying.
Based on the provided reference, here is the specific guideline for home gardeners:
Gypsum Application Rate
According to the reference: "For home gardeners spread 40 pounds of granular grade gypsum per 1000 square feet of soil."
This is a standard recommendation for general soil improvement purposes in a home garden setting.
Application Details
- Amount: 40 pounds
- Area: 1000 square feet
- Type: Granular grade gypsum
- Frequency: One application is sufficient for three years.
- Timing: It can be applied at any time of the year.
Here's a simple breakdown in a table:
| Application Factor | Detail |
|---|---|
| Amount | 40 pounds |
| Area | 1000 square feet |
| Type | Granular grade gypsum |
| Frequency | Once every three years |
| Timing | Any time of the year |
Why Use Gypsum?
While the reference primarily focuses on the application rate, gypsum is typically used to:
- Improve soil structure by helping clay particles clump together (flocculate), which enhances drainage and aeration.
- Supply calcium and sulfur, essential plant nutrients.
- Reduce sodium levels in sodic soils, which can improve water infiltration and reduce toxicity to plants.
Always ensure you are using the correct type of gypsum (granular grade is often preferred for easy spreading) and applying it evenly across the target area.
