[QUOTE="Farmer Roy, post: 4057936, member: 71668"] It's dark now & I have to pay more attention to planter units ( due to what I'm about to talk about ) so I'll be brief. One real problem we have here after even a few yrs of zero till is that are soils become so soft & fluffy & retain moisture, that when planting with disc units we have problems with the discs bulldozing & not turning, the ground just isn't firm enough to drive the disc. Now it's dark & the cold night air has come in, the discs are picking up a bit of mud, the scrapers & gauge wheels are working that bit harder, and everything stops turning. Drive across a roadway or some compacted ground things start turning again. So many of our more fragile soils have been destroyed & pulverised by the plough. No structure. No organic matter. No soil life. Set like cement. Our soils ( here, black soil plains ) are very forgiving to all sorts of abuse - it's amazing the difference a good drought followed by a flood make to these self mulching clays :). But they are very susceptible to traffic & compaction, hence the development of CTF here. Bare in mind with compaction, the worst damage occurs at depth, under the tractor, it is egg shaped & the wheels cause it to bulge up under the tractor ( this isn't visible from the surface, but it's what it does.) There has been a hell of a lot of research into compaction by various organisations on various soil types in Australia [/QUOTE]
