1. What is the McGill Compost Calculator?

The McGill Compost Calculator helps determine the volume of compost needed for a given area based on square footage and desired depth. It's essential for proper soil amendment and gardening projects.

2. How Does the Calculator Work?

The calculator uses the simple volume formula:

Where:

• \( Area \) — Area in square feet
• \( Depth \) — Depth in inches (converted to feet in calculation)

Explanation: The calculator converts depth from inches to feet, then multiplies by area to get cubic feet, and also provides the equivalent in cubic yards.

3. Importance of Proper Compost Volume

Details: Calculating the correct amount of compost ensures proper soil amendment without waste or shortage. The right volume improves soil structure, nutrient content, and water retention.

4. Using the Calculator

Tips: Measure your garden area accurately in square feet. For general soil improvement, 1-3 inches of compost is typically recommended. For new beds, 4-6 inches may be needed.

5. Frequently Asked Questions (FAQ)

Q1: How much compost do I need for my garden?
A: For existing gardens, 1-3 inches is typical. Multiply your garden area by desired depth using this calculator.

Q2: How many cubic feet in a cubic yard?
A: There are 27 cubic feet in 1 cubic yard (3ft × 3ft × 3ft).

Q3: How do I measure my garden area?
A: For rectangular areas, multiply length by width. For irregular shapes, break into rectangles or use online mapping tools.

Q4: Should I buy compost by weight or volume?
A: Compost is typically sold by volume (cubic yards or cubic feet) as moisture content affects weight.

Q5: How often should I add compost?
A: Most gardens benefit from annual compost application, though intensive gardens may need more frequent applications.
