Water is the most important resource on the planet, and without a doubt the place to start. All life is 70% water, water is life. Once the hydro-logical balance of a landscape is restored 70% of the work is done. You should most certainly contour the land and restore the water household of the property as the first step. From here it will be much easier to establish and grow soil enriching crops. Lupin, alder, clover, and nettles are all great species for your situation.
When you create earthworks, adding texture to the land, this will help break up your compacted soil. Worry about restoring the water balance first, then worry about the soil. From this first action all of the life will start coming back. Fungi and bacteria will come back, as will insects and the rest of nature's helpers. Cover crops and mulching will be very important, the surface of the earth should never be exposed to the sun. This makes it so that the soil cannot absorb the rain when it comes, further disrupting the water balance.
Just to clarify, Sepp does not ever burn organic matter for use as a soil amendment. It is much better to return it to the soil in it's natural form and let nature do the work
