Soil advice?

We received the following query about soil texture. Please post your comments below.

I’m an extension soils specialist working in Kansas and have received a request for help from a small airport that has many problems with their grass runways. Has anyone ever tried to change the soil texture before? In this case, they want to add sand in order to improve the soil texture and soil strength. Thanks for any help you can give me! I’m going to email Dr. Unruh at the University of Florida now. Thanks. DeAnn Presley.
