To estimate the amount of soil needed to add to your infield skin to bring it up to the proper grade, use the following formula:

For a more accurate estimation of soil needed, compaction should be factored into this equation as well. Ask your soil supplier for the compaction factor of the soil you will be ordering. If, for example, the CF (Compaction Factor) is 43%, then multiply the amount of soil suggested from the equation above by 1.43. If the compaction factor was 30%, then multiply it by 1.30.
