Soil Amendment
Cubic yards and tons of amendment for a given depth.
About Soil Amendment
Area times depth gives cubic feet, converted into cubic yards for ordering and tons for spreading weight. Organic amendments lighten compacted ground and feed the soil life that roots depend on.
Formula
Soil Amendment
Volume = area x depth; yards = volume / 27; tons = volume x density / 2000
- bulk density
- Pounds a cubic foot of the amendment weighs
