If you use a rototiller, you would apply up to one inch of compost on top of the soil and till it to a depth of five inches of soil.
If you are using a shovel to turn your garden, you could measure the depth of the shovel blade and calculate the depth of the compost needed to accommodate the depth of the shovel blade. Using one-fifth of an inch of compost for every inch of depth of the shovel.
