| Hello. Newbie here.
I'm trying to revitalize a 12'x16' plot of mildly lead-contaminated (50ppm), compacted clay soil, in the middle of a tiny post-industrial 'backyard'. It's been suggested for obvious reasons that I plant in raised beds. Being fall, though, I'd like to start by focusing on improving grade / sub-grade drainage characteristics, so that the area overall is pleasant to garden in. I can post or email photos -- ie, if anyone wants to check things out a bit before making suggestions. Experienced urban gardeners from the Ohio Valley, please show some love. Thanks. |

| As a rule, since plants do not readily bioaccumulate lead the level of lead in garden soils is considered roughly okay to about 300 parts per million. The simplest means of taking care of the problem is to increase the amount of organic matter in the soil and give your plants a choice of better nutrients. As this article from the University indicates most soils have a background level of lead contaimination ranging from 7 to 20 ppm. |

| Thanks, Linda & kimmsr! I will be heeding both of your recommendations! A bit short on time at the moment... However, I should probably state that I've been trying to familiarize myself with studies re lead availability & accumulation in plants. Mainly focusing now on how to best deal with poor drainage and compacted clay subsoil, amidst surrounding concrete, asphalt, etc. Many thanks again for your responses. |
