That is what we have at the farm after doing some digging for our perk test. Actually we have about 4 inches of topsoil, 6 inches of a mix of topsoil and clay, and then at least a couple feet of clay (they only dug down a bit over three feet). It’s not perfect, but it is pretty common for this area and we probably couldn’t have found anything much different if we tried. I guess all that clay could be a bonus if/when we build a pond, but for right now it is kind of a bummer.
The bummer factor is that our ground didn’t perk, so we have to go with a more expensive septic system. If we would have had some good perking land (which we are now finding out isn’t super common in our area) our septic system could have cost as little as $3,000, but since we have to have to install a system that is quite a bit more involved it could cost as much as $7,500. That isn’t exciting, but you need a septic system.
The other side of the soil coin is that it would be nice to build some more topsoil over time so that we could have more organic matter (OM) on our ground soaking up the water (instead of running off the ground). Last summer we collected coffee grounds from a local coffee shop in town and spread them around our garden. Yesterday when my wife was putting in a few plants she noticed more earthworms than the year before in the areas where she heavily put the grounds. Worms are great components of soil building so we will want to encourage their presence as much as possible.
Hmmm… maybe I can get coffee grounds from all over town and fill a spreader!
