A cubic yard of manure typically weighs between 800 and 1,600 pounds, but that range is so wide it barely qualifies as an answer. The actual weight depends on moisture content, animal source, how much bedding is mixed in, and whether the manure is fresh or composted. A soggy cubic yard of fresh dairy manure can tip a scale past 1,700 pounds, while a fluffy cubic yard of dry, composted horse manure with straw might come in under 900. Understanding what drives those differences matters if you are loading a pickup truck, ordering a bulk delivery, or just trying to figure out how many trips your wheelbarrow can handle.
Why Moisture Is the Single Biggest Variable
Water is heavy, and manure holds a lot of it. Fresh manure straight from the animal can be 70 to 90 percent water by weight, which means most of what you are lifting is not manure at all but water trapped inside it. A cubic yard of material that is 85 percent moisture will weigh dramatically more than the same volume at 40 percent moisture, and nothing else you change about the manure will swing the number as much as this one variable.
This is why two piles that look identical in size can weigh very different amounts. A pile that sat in the rain all week absorbs water and gets heavier. A pile that has been turned and air-dried in summer heat loses moisture rapidly and becomes lighter. When sellers advertise manure by the cubic yard, they are selling you a volume, not a weight, and the moisture content at the time of delivery can shift the actual tonnage by hundreds of pounds per yard.
Research on manure handling has consistently found that moisture content is the dominant factor controlling bulk density and, by extension, how much a given volume weighs. Studies measuring manure at various moisture levels and compaction pressures confirm that wetter material packs more densely and weighs more per unit volume than drier material under the same conditions.1PubMed.

Fresh Manure Versus Composted Manure
Fresh manure, the material recently collected from a barn or feedlot, is dense and wet. Depending on the animal, a cubic yard of fresh manure weighs roughly 1,400 to 1,700 pounds. It is closer to the density of water than most people expect, and the reason is straightforward: it is mostly water.
Composted manure is a different product entirely. During composting, microorganisms break down organic matter and generate heat, which drives off huge quantities of water. Active composting during warm months can reduce water mass by as much as 83 percent, and dry matter itself shrinks by roughly a fifth to a third.2Bioresource Technology. Physical changes during active and passive composting of beef feedlot manure in winter and summer The volume also collapses dramatically. In summer conditions with active turning, the volume of a composting pile can drop by about 72 percent during the hot phase alone, with smaller additional losses during curing.2Bioresource Technology. Physical changes during active and passive composting of beef feedlot manure in winter and summer
Here is the part that confuses people: even though composted manure has lost most of its water and a good chunk of its dry matter, its bulk density actually increases during composting, often by three to four times the starting value. That seems contradictory until you realize that the volume shrinks even faster than the mass does. The finished compost is denser per cubic foot than the original material. But you are buying a cubic yard of finished product, not a cubic yard of the original pile. Because the finished compost is drier and lighter overall, a cubic yard of it typically weighs less than a cubic yard of fresh manure, often in the range of 800 to 1,100 pounds depending on how dry it is.
How the Animal Source Changes Things
Not all manure starts from the same place. Cattle manure tends to be wetter and heavier per cubic yard than horse manure, partly because cattle produce a sloppier product and partly because horse manure usually contains more bedding material. Poultry manure, or litter, is its own category: it is often collected with wood shavings or other bedding and can vary wildly in density depending on how much litter is in the mix and how long it has been stored.
Here is a rough guide for fresh, as-excreted manure in cubic-yard terms:
- Dairy cattle: 1,400 to 1,700 pounds per cubic yard, depending on how liquid the manure is and how much bedding is mixed in.
- Beef cattle (feedlot): 1,200 to 1,500 pounds per cubic yard, slightly drier than dairy because feedlot manure often sits on dirt or packs and loses some moisture before collection.
- Horses: 900 to 1,300 pounds per cubic yard, lighter because horse manure is more fibrous, drier, and nearly always bulked up with straw or wood shavings.
- Poultry litter: 800 to 1,200 pounds per cubic yard, highly variable because the ratio of droppings to bedding material differs between broiler houses, layer operations, and backyard coops.
- Sheep and goats: 1,000 to 1,400 pounds per cubic yard, the pellet-like consistency means these pack fairly tightly.
These are ballpark figures. The actual weight you experience depends on everything discussed above, especially moisture. A cubic yard of rain-soaked horse manure can weigh as much as fresh cow manure, and a cubic yard of kiln-dried poultry litter can be surprisingly light.
Bedding and Amendments Make the Pile Lighter
Most manure you encounter in the real world is not pure. It arrives mixed with whatever bedding the animals were living on: straw, wood shavings, sawdust, sand, or shredded newspaper. The type and amount of bedding dramatically affect the weight per cubic yard.
Straw and wood shavings are light and airy. They bulk up the volume without adding much weight, so manure mixed with a lot of straw weighs less per cubic yard than manure collected without bedding. Research comparing wood-chip-bedded and straw-bedded beef cattle manure found meaningful differences in the chemical and physical properties of the finished compost, reflecting how much the bedding material changes the character of the final product.3PubMed Central. Physical and chemical changes during composting of wood chip-bedded and straw-bedded beef cattle feedlot manure Wood chips tend to produce a lighter, more carbon-rich compost, while straw breaks down more quickly and the resulting compost is denser.
Sand-bedded manure, common in some dairy operations, goes in the opposite direction. Sand is heavy. Even a modest amount mixed with manure can push the weight per cubic yard well above what you would expect from manure alone. If you are buying bulk manure from a dairy that uses sand bedding, be prepared for heavier loads and harder shoveling.
Compaction and Pile Depth Change the Density
A cubic yard scooped from the top of a manure pile does not weigh the same as a cubic yard pulled from the bottom. The weight of material stacked above compresses the layers below, squeezing out air and packing the manure tighter. Research measuring bulk density at various depths in composting piles found that density increases predictably with depth, following a consistent mathematical relationship between how deep you go and how dense the material becomes.4Transactions of the ASABE. Determination of Initial Bulk Density in Different Depth Layers of Composting
This has practical implications. If a landscaping company fills your order from the bottom of a tall stockpile, you may get a heavier cubic yard than if they scoop from the top of a freshly dumped, loosely piled batch. The difference can be substantial. A pile that has been sitting for weeks and has settled under its own weight is noticeably denser throughout than a pile that was just turned or recently delivered.
The same principle applies to your truck bed. If you tamp or pack the manure down, you are fitting more mass into the same volume. A loosely tossed cubic yard and a well-packed cubic yard are not the same weight, even though they take up the same space on paper.
Seasonal Swings in Weight
Weather affects manure weight in ways that matter for anyone buying or moving it. In summer, exposed piles dry out faster, lose moisture to evaporation, and weigh less per cubic yard. In winter, manure can absorb rain and snow, and in freezing climates, it may partially freeze, trapping moisture that would otherwise drain away. A frozen cubic yard of manure is heavier than the same pile would be in July, and it is also much harder to break apart and spread.
Composting itself behaves differently by season. Active composting in summer produces much greater volume loss and water loss than passive composting in winter. Winter passive composting may only reduce volume by about 34 percent during the hot phase, compared to 72 percent for summer active composting.2Bioresource Technology. Physical changes during active and passive composting of beef feedlot manure in winter and summer If you are buying composted manure in early spring, it may not have lost as much volume and water as the same product would by late summer, meaning you could get a wetter, heavier yard of product than expected.
Practical Weight Estimates for Common Situations
If you are trying to figure out whether your truck can handle the load, here are the situations most people actually face:
A standard half-ton pickup truck (like a Ford F-150 or Chevy Silverado 1500) has a payload capacity of roughly 1,000 to 2,000 pounds depending on the configuration. A full cubic yard of composted, reasonably dry manure in the 800 to 1,000 pound range fits within most half-ton trucks’ limits. But a cubic yard of fresh, wet cow manure at 1,500 or more pounds could push a lightly-rated truck beyond its safe payload, especially once you add the weight of the driver and any passengers. If you are hauling two cubic yards of anything moist, you likely need a three-quarter-ton or one-ton truck.
A standard wheelbarrow holds about three to five cubic feet. Since a cubic yard is 27 cubic feet, you are looking at roughly six to nine wheelbarrow loads per cubic yard. Each wheelbarrow trip with composted manure weighs around 100 to 200 pounds, which is manageable for most people. With fresh, wet manure, each load is closer to 250 to 350 pounds, which is enough to strain your back and your wheelbarrow’s tire.
For garden bed calculations, most recommendations call for spreading composted manure two to four inches thick. A cubic yard covers roughly 80 to 160 square feet at that depth. If you are ordering in bulk for a large garden, one cubic yard goes further than most people expect, and you can estimate total weight accordingly.
Why Sellers Price by Volume, Not Weight
You might wonder why manure and compost are almost always sold by the cubic yard rather than by the ton. The answer is partly practical and partly economic. Volume is easy to measure with a front-end loader bucket. Most landscape supply yards know the capacity of their buckets and scoop accordingly. Weighing every load would require a truck scale, which is expensive to install and slows down operations.
But there is a less obvious reason. Because moisture content fluctuates so much, selling by weight would create wildly inconsistent pricing for what is essentially the same product. A yard of compost that sat in the rain might weigh 30 percent more than the same compost in dry conditions, but it is not 30 percent more valuable to you as a garden amendment. The extra weight is just water. Volume-based pricing, while imperfect, gives you a more consistent measure of how much actual organic material you are getting.
The downside is that when you care about weight, as you do when loading a truck or trailer, volume-based purchasing leaves you guessing. This is why it helps to know the rough density of what you are buying and to ask the seller about the moisture condition of their current stock. A supplier who has been turning and aerating their compost pile will typically have a lighter product per yard than one whose pile has been sitting in a low spot collecting runoff.
The Density Standard That Underpins These Numbers
Agricultural engineers do not just guess at manure density. The American Society of Agricultural and Biological Engineers (ASABE) maintains a standard called ASAE D384 that provides reference values for the physical properties of various manure types. Research measuring the density of different manure products has found results in close agreement with this standard, which lends some confidence that the ranges quoted in extension publications and industry guides are grounded in actual measurement rather than folklore.5Applied Engineering in Agriculture. PHYSICAL AND RHEOLOGICAL PROPERTIES OF MANURE PRODUCTS
The standard covers various forms of manure from different animals, at different moisture levels, in different handling states (liquid, slurry, semi-solid, solid). It is the basis for engineering calculations used in barn design, storage facility sizing, and manure transport logistics. You will never need to consult it directly, but knowing it exists is useful if you ever encounter a surprisingly precise weight claim about manure. That number probably traces back to this standard or to research validated against it.
When the Advertised Yard Is Not Really a Yard
One final complication worth mentioning: not every “yard” you purchase is a true cubic yard. Some suppliers use loader buckets that are nominally one cubic yard but are not precisely calibrated. A heaping bucket delivers more than a level one, and different operators heap differently. Some bulk delivery trucks measure by the scoop rather than by precise volume. And bagged manure sold at garden centers uses yet another measurement system, typically sold by weight (pounds per bag) or by a stated volume in cubic feet, which you would need to convert yourself.
If precision matters for your project, it can be worth asking the supplier how they measure. A reputable landscape supply company will know the rated capacity of their buckets and can tell you whether they load level or heaping. For large orders, some suppliers will weigh the loaded truck on a scale, giving you an exact tonnage that you can use to back-calculate the density of the product. That is the most reliable way to know what you are actually getting, though most home gardeners will never need that level of detail.
