Improving clay soil
We have about 2.5 acres of turf at our nursery and most of it is all clay. In the fall we're going to incorporate mulch but I was thinking of adding some sand now after I aerated. Would this be ok and if so, what grain should I go with?
I work with non-commercial clients, so I think the best contact for you would be Dr. Lloyd Nackley, who is the nursery crops researcher at the North Willamette Research and Extension Center in Aurora. The number for NWREC is 503-678-1264, and his email is Lloyd.email@example.com. We also have an Extension soil scientist based on campus, Dan Sullivan, that could provide some guidance and Lloyd can put you in touch with him. I hope this is helpful, feel free to write directly to my email with further questions. Thanks!
