Interesting guide. Thanks for sharing. A bit concerning the site doesn't have a soil testing guide anymore, though. The theories in the article let alone this subject itself kinda rely on soil science. Regardless, crop rotation is very important and should be utilized more in all farming. Monocropping is extremely damaging to the environment because it destroys soil diversity, which reduces nutrients and reduces the wildlife ecosystem involved in the process.
I admit I only recently begun to learn about the concept of crop rotation, but it is one that I am attempting to incorporate into this year with my garden. Especially with me having 16 plants specifically in large pots instead of my raised beds, I have to be more aware of that practice.
