Five Lessons We Learned About Lead in Soil

is problem is in urban areas. Towards that end I though I would share five things that we learned from our backyard lead crisis: Buyer Beware. When you are shopping for a house do multiple soil tests. Once you buy the house it’s too late. Real estate contracts in California (and I suspect elsewhere) have been loaded up with disclaimers about lead and old houses. I’m no legal expert, but I suspect it would be difficult to go after th...

What We’re Going To Do About That Lead

White sage, yarrow, rosemary and aloe vera–the kind of plants we’ll be planting more of. Let’s assume that we have a lead problem in our backyard. That’s a big assumption at this point because we now have two very conflicting test results. But, for the sake of an argument, let’s say the first alarming test is true, what are we going to do about it? These are the options: Radical remediation: Remove all t...

Lead Update

that “plant available” is different than the total amount of lead in the soil. The total amount would be about ten times higher or 1,120 ppm. According to the University of Minnesota Extension Service, Generally, it has been considered safe to use garden produce grown in soils with total lead levels less than 300 ppm. The risk of lead poisoning through the food chain increases as the soil lead level rises above this concentrati...

Testing the Lead Testers

n extractant, AB-DTPA (ammonium bicarbonate Diethylene Triamine Pentaacetic acid). Here’s how Wallace described their lead testing techinique, We use AB-DTPA (ammonium bicarbonate Diethylene Triamine Pentaacetic acid). It is a gentle extractant and it mimics roots in extracting minerals from the soil. Most often environmental tests are made with boiling acids which are more aggressive than roots. The AB-DTPA method is a standard testing me...

Remember to Label Those Jars!

e no idea. They were probably the result of some late night canning frenzy two years ago. At the time I probably thought to myself, “I’ll label them in the morning.” Not only should the jars be labeled, but it would also have been nice to have some notes on the recipe I used and where the fruit was sourced from. To this end I’ve started a preservation diary in a useful program called Evernote. Perhaps I should get a tatto...

Lead Update

Our post about a high soil lead level needs an update. I asked my doctor do a blood test to check for lead levels since we’ve eaten plants grown in the backyard and done a whole lot of digging over the past 13 years. The good news is that no lead showed up in my blood. In the interest of “testing the testers,” I took one soil sample and split it in three, sending one sample to Wallace Labs, one to the University of Massachuse...

Broom Corn–or is it Broomcorn?

Mrs. Homegrown here: This summer I suggested we plant broom corn for no other good reason than I saw the seed pack at the nursery and thought it would be fun to make a broom. (This sort of temporary insanity often overtakes me in the seed aisle.) So without knowing anything at all about broom corn or broom making we planted a block of the stuff. Maybe I should have done a little research into broom making before planting, but I let it slide ...

Urban Chickens and Lead

From the One More Thing To Worry About department, the New York Times has an article on lead levels in eggs laid by urban chickens “Worries About Lead for New York City’s Garden-Fresh Eggs.” According to the article, the lead levels found in New York City’s home grown eggs ranged from none to over a 100 parts per billion. Since the FDA does not have an acceptable lead level in eggs it’s difficult to interpret the results...

Healing the yard with a huge compost pile

The new compost pile is covered with a tarp to keep moisture in. Eventually it will fill this whole space. In the background you can see our leftover adobe bricks. So–our regular readers will know that we have high levels of lead in our back yard soil. We’re dealing with this by filling most of our yard with mulch and perennial natives to lock down the soil (lead laden dust is bad) and to diversify the local ecosystem. Mea...
