No need to. Trees bury about half their biomass as roots. Then leaves and branches fall on the ground and bury older leaves and branches. Of course it's long and inefficient (because of fungus, bugs...) but plants do it without our input so we need to let them do their thing. Calling this process net neutral is a falsehood.

Of course it's not enough to balance human emissions. Sequestering carbon in fields, as pointed out, is a win-win solution which may do a large part in canceling emissions.
