Question
my grass was burnt by calcium chloride from the tires of a car.  Any way to fix other than watering?

Answer
From the Rim Guard Liquid Tire Ballast page on its website:

'Calcium Chloride is toxic. It will contaminate soil and prevent plants from growing if it spills. Many states and municipalities classified it as a hazardous waste requiring cumbersome and expensive handling and disposal procedures.'

Sorry.  You asked.

Yes, it does seem that the least of your problems is the burning of your Grass.

It appears not only that your Grass is damaged beyond repair, but growing more Grass where it used to be is going to be at least for the time being impossible.

'Sodic Soil' -- soil with a pH above 8.5 -- is sometimes corrected quickly with SMALL applications of Calcium Chloride.  But since this is a SALT, it must be used sparingly.  Besides, you did not intend to apply this to fix the pH.

Watering may not the best way to handle this.

Although Calcium Chloride is highly water soluble, if there are indications that it is not leaching out of the soil fast enough, scoop up the tainted CC'd soil and bag the stuff in large black plastic bags, then toss.  REPLACE the removed soil with fresh, healthy soil.  Water will dilute Calcium Chloride, but it is so strong that if it does not completely eliminate it, it could take years to leach out completely.  You want to erase it from your plot.  You want things to grow like it was never there.

A soil test will tell you if you have succeeded, as well as supply a lot of other excellent information about the dirt in your Lawn and Garden.  Send your zipcode and I will give you the information on your local Cooperative Extension for getting this done at a very reasonable cost.

Sorry about your predicament.  Good luck on the water treatment.  rsvp with your zip.
