Why two suppliers deliver different weights for the same order
Published densities for topsoil run from 940 to 1400 kg per cubic metre. On a 2.43 cubic yard order that is the difference between 1.93 and 2.87 US tons. No supplier states a moisture condition, and topsoil after rain is much heavier than the same soil dry. The band is wide because the material is.
