Teaming with Microbes/Nutrients by Jeff Lowenfels

I am curious as to what you folks think of these two books:

Teaming with Microbes by Jeff Lowenfels and Wayne Lewis

Teaming with Nutrients by Jeff Lowenfels (the latter)

I have read the first and am about to start the second. Any thoughts would be greatly appreciated. Many thanks.

I own a copy of Teaming with Microbes and highly recommend reading it... I didn't know about the second!
