Fill Dirt Vs Topsoil
There are two main types of dirt: fill dirt and topsoil. The former lies below topsoil and is typically composed of rockier, less organic material. It’s often used to fill holes or elevate the ground. It provides a sturdier base because it doesn’t break down as much as topsoil.
Topsoil is the darker-colored, uppermost layer of dirt. It’s typically 4 to 12 inches deep and has more organic material and nutrients than fill dirt. Most soil activity by microorganisms happens in this layer. This and that fact that it provides more oxygen to plants makes it better for gardening.
However, because it contains more organic matter, topsoil tends to break down as air pockets collapse. This makes it suitable only for the uppermost layer of a landscape. It’s also more vulnerable than fill dirt to erosion. Therefore, always place topsoil over fill dirt after the fill dirt has been set.
Topsoil is typically measured in cubic yards. A cubic yard is 27 cubic feet, and a cubic foot is 12x12x12 inches.
Dirt Connections outlines two methods you can use to determine how much topsoil you need:
Suppose you have a flower bed that’s 6 inches deep, 12 feet long, and 12 feet wide. Follow these steps:Convert all measurements to feet. Six inches is 0.5 feet.Find the number of cubic feet by multiplying the dimensions: 0.5x2x12 feet = 72 cubic feet.Find the number of cubic yards by dividing the number of cubic feet by 27.72 cubic feet / 27 cubic feet = 2.67 cubic yards to fill your flower bed.
Suppose you have a flower bed with the same dimensions as before.This time, convert the measurements in feet and inches into yards. There are 36 inches in a yard, so six inches is 0.167 yards. There are 3 feet in a yard, so 12 feet is 4 yards.Multiply the dimensions in yards to find the number of cubic yards. 0.167 yards x 4 yards x 4 yards = 2.67 cubic yards.
How Much Does Topsoil Weigh?
According to Dirt Connections, a cubic yard of topsoil weighs about 1,080 pounds. However, debris and moisture can make it heavier. Grow Your Yard states that topsoil can weigh between 1,400 and 2,000 or more pounds. Because topsoil contains less sediment than fill dirt, its weight tends to be more consistent.
