Does Sand Improve Clay Soil Drainage?: University of

Jan 31, 2018 When sand mixes with clay, it creates a soil structure akin to concrete. To create a real change in a clayey soil structure, you would need to add a 1:1 ratio of sand to clay. Considering the actual volume of clay soil underfoot, that equates to a lot of sand. It is far more practical to use organic matter to help break up clay soil.

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.
