Compost needs for a garden

[Lara Schneider]

Hello-

I am a gardener and need help figuring out how much compost I need for my garden sites. I have three different sites and each are of varying fertility levels.
Someone has offered to donate free compost to this project which is wonderful!

How do I convert square feet to figuring out how many yards of compost I will need? One of the site is very poor soil quality so I would love to lay 18" of compost over all of the growing space.

Thank you kindly,
Lara Schneider

The formula is:

Volume = Area * Height

But, if Area is in square feet, the height must be in feet, so convert the height in inches to feet first.

The resulting Volume will be in cubic feet, you just then need to convert cubic feet to cubic yards by dividing by 27.

"yards" is just a shortned form of cubic yards.
