1. What is the Compost Calculation?

The compost calculation helps determine how much compost you need for your garden based on the area to be covered and the desired depth of compost application.

2. How Does the Calculator Work?

The calculator uses the compost equation:

Where:

• \( Garden\ Area \) — Area of garden in square feet (ft²)
• \( Depth \) — Desired compost depth in inches (in)
• 12 — Conversion factor from inches to feet

Explanation: The equation converts the depth from inches to feet and multiplies by the garden area to get cubic feet of compost needed.

3. Importance of Compost Calculation

Details: Proper compost calculation ensures you purchase or prepare the right amount of compost for your garden, avoiding waste or shortage.

4. Using the Calculator

Tips: Measure your garden area accurately in square feet and decide on the desired compost depth in inches. Typical compost depths range from 1-4 inches for top dressing.
