I hear what you are saying on the aspect of forage quality too…..I listened to a seminar not long ago by Dr Craig Harper on just what you're talking about…….The way in which I suspect that this method could have an impact on quality is through species diversity….More abundance of higher quality plant species…..I have seen through my T&M food plot tests that species composition changes as the soil organic matter % changes…..as the conditions change the plants change…..Could we promote a better plant community through improving the soil? Like I said previously, I think it depends on what impact you’re currently having on the soil by setting succession back using fire….Do we even know?....How does that vary from one soil type to another? Let's not bury our heads in the sand the same way we did with farming practices
