I'm sure they did use slash and burn techniques, plus they had to strip the land of the vegetation that's already on it, and crops tend to be smaller sources of carbon sinks than natural vegetation.
Basically, a turnip eats up a lot less CO2 than an oak tree...and the turnip isn't around all year long.
But also using your example of a deciduous tree, the tree goes dormant and does not photosynthesize when the leaves fall off.
Also many vegetables can grow in the space of one oak tree.
Maybe I can find a study comparing the two.
