Test for the soil's pH levels. Add amendments as outlined in the soil test.
Break up the soil with a garden tiller to a depth of 6 inches. Rake through the soil and remove large debris such as rocks or sticks.
Spread soil amendments over the soil to a depth of 4 inches. Mix them with the soil by passing the tiller over the soil again.
Smooth out the soil and re-grade it with a rake. Slope the soil gently away from the home with the rake.
Water the soil 24 hours before laying sod to ensure that soil is as damp as a wrung-out sponge.
