cat litter for clay content?
I know that calcined clay litter does not serve as a drainage-enhancing soil lightener as some have mistakenly thought. It softens into a fine-textured slurry after being wet for a long time. Rather, I was wondering if it could be used effectively to add clay to sandy soil. Just 10% fine clay adds substantially to a soil's ability to retain nutrients and water.
American cat litter is usually made of montmorillonite, which is similar to bentonite, a fine clay that has been used in soil mixes. It is calcined or baked, but not enough to fuse it into a permanent solid mass.
Anybody know about this or have a good link?
