Another feature I like in the lawn and the garden is that many weeds are not mycorrhizal. The root biomass of the lawn goes down 17 inches or more and the garden plants treated with VAM fungi all have much larger root systems. >> Grass that produces less grass? That's good? I'm confused (but please spare me the explanation). You say many weeds are not mycorrhizal. Other than your observations, how do you know? You have references? If roots treated with this fungi are so much more efficient, why do the plants need larger root systems? Seems like they could grow without putting extra effort into un-needed roots. I hate to ask these questions because I'm really tired of hearing about this stuff. I'll have to learn to use my delete key more often. Sorry for whinning. Tom
