This is a question that is often asked, and there really isn’t a definitive answer. The truth is, it all depends on the ingredients in your compost and how dense they are.

Compost is a key ingredient in any healthy garden. It helps improve drainage and aeration in the soil, while also providing vital nutrients for plants. But how much does a yard of compost weigh?

This can be a tricky question to answer, as compost can vary greatly in density. For example, dry leaves and twigs will weigh much less than damp, manure-based compost.

To get a better idea of how much your compost will weigh, it’s best to consult a professional. They will be able to give you a more accurate estimate based on the type of compost you’re using.

The Benefits of Compost

Compost is organic matter that has been decomposed and recycled as a fertilizer and soil amendment. Compost is rich in nutrients that help plants grow, including nitrogen, phosphorus, and potassium. It also helps improve soil structure, aeration, and water retention.

Composting yard waste such as leaves, grass clipping, and garden trimmings reduces the volume of waste going to landfills. It also reduces methane emissions from decomposing yard waste. Methane is a powerful greenhouse gas that contributes to climate change.

Yard waste makes up about 20 percent of the solid waste generated in the United States each year. Composting this yard waste prevents it from being sent to landfills where it would decompose and release methane into the atmosphere.

How Much Does a Yard of Compost Weigh?

Assuming you are talking about dry, finished compost, it depends on the ingredients used and how finely it was composted. A yard of leaves will weigh considerably less than a yard of manure. In general, a cubic yard of dry compost will weigh between 600 and 800 pounds (272 to 363 kg).

The Best Way to Use Compost

There is no “right” way to use compost. It all depends on your needs and goals. Some people prefer to mix compost into the soil before planting. Others top dress their plants with a layer of compost during the growing season. And still others use compost as mulch to help suppress weeds and conserve moisture.

Compost can also be used in a variety of other ways:

-As a potting mix for houseplants
-As a soil amendment for potted plants
-Mixed with water as a liquid fertilizer
-Added to worm bins or compost bins

How to Make Compost

Although units of weight or volume are the most common way of measuring compost, particularly when buying in bags, there are actually a few other measures you could use. Here are some other measurements of compost and how they relate to each other.

1 bushel = 8 gallons
1 cubic yard = 27 cubic feet
1 ton = 2,000 pounds

So how much does a yard of compost weigh? If we assume that 1 cubic yard of compost weighs 40 pounds (16 ounces per gallon x 8 gallons), then 1 cubic yard of compost would weigh 2,880 pounds or 1.44 tons.


After doing some research, we have concluded that a yard of compost weighs anywhere from 800 to 1,200 pounds. This weight can vary depending on the type of compost (e.g. leaves, manure, grass clippings) and the water content.
