read about the soil food web. Googling this or reading the book, the soil food web by jeff lowenfels will give you all the evidence and knowledge you need about bacteria and fungi. It actually is pretty standard to all gardens and dirt and some special moves should be made with comtainer gardens and or any soil where chemical ferts or P products over 10 have been used.

Chem salts kill your beneficial organisms in the soil. I use rooters myco for 10 dollars, and super plant tonic, and worm castings and compost tea (which is all you ever rally need) to get the beasties back or into my soil. Also I feed them some molasses to feed them. Once in the soil the plant will attract the ones it likes. Most annuals will choose an endo fungi and the bacteria to go along with it. It will need bacteria more than fungi in the soil but all plants need the myco for the roots.

Plants without myco are pathetic I have seen in many photos, right next to plants easily twice as big. It is a big deal to have myco, also let ferts need to be used.
