Anyone studied work of Dr. Tiedjens (1940's)? I cannot find anything but a wikipedea page and sales literature. Just wondering if he was a legit scientist, or a salesman. Gruver, have you seen this work? You previously quoted soil science by Jethro Tull, you must know something.
Anyone have any experience what happens after years of using his practices?
