Improving Clay Soil Lawn Care Academy

For sand to be effective, use the largest coarse sand particle size available. Finer sand particles can fill the tiny holes in clay structure producing something like concrete. Sand based soils have sand volumes at least 50% of the volume of clay. To produce your own sand based soil you would need a tremendous amount of sand for a home lawn.
