I completely agree with yall about the smell being a special part about it….But if you want to smell the really sweet stuff then stick your nose off in some of this…..That the same smell but a little stouter…….Its of a “release” of organic nutrients, compounds, microorganisms,……releasing it burns it……burning it too much creates a deficit in the cycle organic matter…..long term deficits eventually go to zero and then you’re just smelling the ground up rock in your fields with a small annual release of any minor amount of humus that might have been built...."soil" is a combination of the ground up rock in the deep sublayers of the earth combined with the decayed organic matter from the plant life above.....without the organic component you only have ground up rock and only half of the recipe for "soil"....one of the reasons that base soil is different from place to place is because the base rock in the sublayers is a different type of rock
