Straw might help for the carrot soil,
@ducks4you . However, this was a bed that was loaded with frost-killed plants in the Fall of 2019. So, the organic matter was down there but may not have decomposed enough to be of benefit.
@ninnymary once asked me why I don't screen the rocks from the soil. This would be a BIG task since, I'm not kidding (!), some of my garden soil must be 50% rocks.
Oddly, this year's carrots were in the "better" soil for rocks and last year's carrots couldn't have been in more rocky ground. The 2019 carrots were the best crop I've had since I left that other garden years ago where the sand content was so high (big rocks but few of them).
