recycling excess soil

Sun, 07 Oct 2012 08:04:07 PDT
I am experimenting with solarizing soil. 

Although my purpose is to rid it of Oxalis pes-caprae, 

it would also sterilize for other purposes. 
My purpose requires 135 F for 2 hours. 

Not all days are sunny enough to reach that.

Here is a photo of my setup:…

It is small scale. I can do 5 buckets of soil each sunny day. 

It takes a lot of effort to fill the bags and secure the plastic outer bag.
I have two other solarizing experiments in progress but they do 

not reach as high temperature.

I'll report late this winter whether the O. pes-caprae was successfully eradicated.
