The short answer is: yes. Application of ground organic material will soften and amend clay soil.
In some settings ground up organic material is a less obvious way to sheet compost. If your Home owners association (or lease) has covenants against composting, this may be one way to step around those covenants. You should read your HOA or lease first.
What sheet composting isn't, is it does not act like seasoning your soup. A light sprinkle don't fix what ails clay in your garden. Composting is the action of repeated and persistant application of organic material.
Like weekly or monthly for years, will change soil. A spritz will be inadaquate to your need.
