Clearing a field

When I have the chance to open new farmland,I like to burn it off like the Indians. It burns off the weed seeds and releases carbon from the fire. It also gives a clearer view of what you are dealing with. You can see the slopes of the land and possible problem spots.i like fire too.this new property has not been worked in 20 years.the ground is fresh.a soil test will round of the then know what it needs
