We have clay too. Haven’t plowed in years.
It will probably break down over the course of a year. What doesn’t will plow in. We did that for a few years.
This will add a LOT of organic matter to your soil, it won’t be ‘clay’ in 5 or 6 years like it is now.
The gravel parking lot I use as a second plot is now ‘dirt’ with some gravel rocks in it.
awesome!
I guess newspaper and boxes are made from trees, providing organic material...
