1. What is the Compost Volume Calculation?

The compost volume 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 simple formula:

Where:

• \( Area \) — Garden area in square feet
• \( Depth \) — Desired compost depth in inches

Explanation: The calculator converts depth from inches to feet (dividing by 12) and multiplies by area to get cubic feet. It also provides the volume in cubic yards (dividing by 27).

3. Importance of Compost Calculation

Details: Accurate 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. Typical compost depth ranges from 1-3 inches for top dressing to 4-6 inches for new beds.

5. Frequently Asked Questions (FAQ)

Q1: How deep should I apply compost?
A: For existing gardens, 1-3 inches is typical. For new beds, 4-6 inches provides better soil improvement.

Q2: How do I measure my garden area?
A: For rectangular areas, multiply length by width. For irregular shapes, break into smaller rectangles and add them together.

Q3: How much does a cubic yard of compost cover?
A: One cubic yard covers about 100 square feet at 3-inch depth or 50 square feet at 6-inch depth.

Q4: Should I account for compost settling?
A: Yes, compost settles about 20-30% over time. You may want to add 25% more than calculated.

Q5: Can I use this for mulch calculations?
A: Yes, the same calculation works for mulch, though application depths may differ (typically 2-4 inches for mulch).
