Carbon Sequestering

[Hopalong]

See suggestions that grasslands sequester more carbon than other land uses.
Would be okay except we need annual crop production to provide much of world's food supply.
Research with zero tillage and returning crop residues to soil indicates organic matter can be maintained in thin black soil zone when used for crop production.
Might be best to use these soils for annual crop production and look to other soils to maintain as or convert to grassland with aim to sequester carbon and satisfy demands from environmentalists.
Observation on own farm where we have black soils and some grey wooded is that black soils have more organic matter and that tree cover likely results in less carbon sequestering.

Well, that puts our farm in question. We are kinda.in the transition zone. Moist dark brown to thin black.

Will it still be OK for the guys in the black zone to burn it black or use tillage to blacken it?

Come on hoppy, stir the pot harder.... seeding must be preoccupying people's minds.

Some around here talk about going to firewood as farm heating fuel.
Saw it used in Brazil a few years ago used for grain drying.
Wonder how it resonates with tree huggers?

I thought growing green grass and crops SEQUESTER, but dead/mature/decaying plants RELEASE carbon. So no gain, or a plus then minus?
