How to Repair Compacted Soil
I live in Queen Anne’s county in a neighborhood that was formerly a soy bean farm. In several of the common areas we are having difficulty getting grass to grow. Some residents want to install irrigation but I suspect it may be that the soil is compacted. The areas were aerated and some top soil was added but still there are bare spots and lots of weeds are growing. The soil tested fine for nutrients etc. If the problem is compaction shouldn’t the soil have been amended down to 6-8 inches? Neighbors’ lawns near these areas are doing okay with irrigation. I suspect that the builder didn’t really bother to properly prepare the common areas as he did for individual lots and or that there may be construction debris or drain pipes under some of these areas. Any suggestions as to what we might be able to do to solve this issue before installing irrigation. Thanks you.

If you are going to install an irrigation system, you can till the area, amend the soil with organic matter, select recommended seed cultivars, final grading and seeding, and proper care after seeding. See our publication for step by step information page 7.
