Plan of soil regeneration with tractor and implements:
The only reason to disturb cropland soil through various types of
tillage, including inverting the soil or rototilling is to shape
terrain, terraform it, create drainage systems, channel water
channeling and create a system of linked,integrated, diverse garden
sites with either rows (hills and furrows), flatland gardens or raised
beds. This, if it needs to be done at all, should only be done once, i.e
once for all time, followed by no till or minimal till agriculture,
managed with human powered equipment and hand tools. Land with heavy,
compactable soil, as Mollison says, may greatly benefit from tillage.
The very best and often the only implement needed is the Yeomans plow.
The beauty of this tool is that it can be used repeatedly with minimal
disruption of the life cycles of soil dwelling creatures. Bottom
plowing, disking, rototilling and even hilling and bedding, if done with
any regularity, can in some cases decrease soil tilth and water holding
capacity, increase compaction and destroy soil life. If heavy tillage is
to be done, it should be immediately followed with cover crops, mulch,
compost and possibly mineral fertilizers and left to rest for a yer or
two; best plan is to divide the land into sections and rotate one
tillage and a two year fallow stage procedure through all the sections,
one at a time, or two at a time, allowing the fully restored,
naturalized sections to be planted with crops for harvest. For those who
can afford to own or rent a Yeomans, annual use of this implement on
difficult soils (see the diagram in Mollison's book - see page posted
here) is appropriate and healthy and can produce miraculous results in
harmony with Nature. Here are pix of the Yeomans three shank plow and a
large hiller bedder I used to own and used exactly the way I described
above.
