One last thought. Setting a fire on my own ground scares the pissouttame every single time and honestly it should for you too. Fire is...well....fire. Plan, plan, plan, have water, have enough help on hand, submit a fire plan to your forestry + fire dept, tractor and disc close by + have the rural fire dept on speed dial.
Burning really and truly isn't that hard, just don't try to bite off more that you can chew and prep pre prep. We've completely canceled tiny burns on just 2ac because conditions were altogether abysmal. If the fire would have ran the wrong direction and gotten out could have torched a BUNCH of ground.
With fire you gotta gotta pick your fights and conditions. It's FIRE. If conditions aren't right go spray privet or bush honeysuckle. Spread lime. Do a wieny roast. Set traps. Change the oil in your 20 yr old truck.
Don't mess with it or take shortcuts.
