Only in the short term. Farmland and forests are approaching different equilibrium points. There’s a few forests that have stayed that way for millions of years. Go to Daintree in Australia, dig down a deep as roots go, count up the carbon in a given acre, and divide by a 180 million and you get essentially 0/year as the long term sequestration rate. Transitions between forests and farmland basically store or release a fixed quantity per acre though it’s a slow process for deep root systems. In that context sure you can look at farming as releasing carbon because of the recent expansion of farming, but the numbers aren’t a fixed constant.
