1. What is the Compost Calculation?

The compost calculation determines how much compost you need to cover your lawn area at a specified application rate. Proper compost application improves soil health and lawn vitality.

2. How Does the Calculator Work?

The calculator uses the compost equation:

Where:

• \( lawn\_area \) — Lawn area in square feet (ft²)
• \( application\_rate \) — Compost application rate in cubic yards per square foot (yd³/ft²)

Explanation: The equation calculates the volume of compost needed based on your lawn size and desired application thickness.

3. Importance of Proper Compost Application

Details: Correct compost application improves soil structure, provides nutrients, enhances water retention, and promotes healthy microbial activity in your lawn.

4. Using the Calculator

Tips: Measure your lawn area accurately. Typical application rates range from 0.002 to 0.004 yd³/ft² (about 1/4 to 1/2 inch depth).

5. Frequently Asked Questions (FAQ)

Q1: What's a typical compost application rate?
A: For lawns, 0.003 yd³/ft² (about 1/3 inch depth) is common. This equals about 1 cubic yard per 300 square feet.

Q2: How do I measure my lawn area?
A: Break irregular lawns into rectangles, calculate each area (length × width), and sum them. Alternatively, use online mapping tools.

Q3: Can I apply too much compost?
A: Yes. Over-application (more than 0.005 yd³/ft²) can smother grass and create nutrient imbalances.

Q4: When is the best time to apply compost?
A: Early spring or fall when grass is actively growing but temperatures are moderate.

Q5: Should I till compost into my lawn?
A: No. For established lawns, simply spread compost over the surface. It will work into the soil naturally.
