A little while back, Robb dug up a sampling of our garden soil and sent it to the University of Massachusetts for analysis. Now, this may seem a bit backwards, because I had already started germinating seedlings for my future vegetable garden. I'll admit it: I was in denial about all the paint chips that had fallen off our garage over the years. I had no particular plan about what to do if the tests revealed that our soil was contaminated with lead.
But as it turns out, I had nothing to worry about. Our soil's lead levels are remarkably low. We don't have toxic heavy metals in our soil.
Our garden soil is basic (as opposed to acidic), probably from years of dumping fireplace ashes out back.
We also have freakishly high levels of phosphorus and potassium, and "significant" levels of nitrogen. We have a good amount of organic material in the soil.
I no longer have to fret about planting a poisonous urban vegetable garden.
