Graham White used clay spreading to fix non-wetting soils on his farm near Badgingarra, pushing clay with a dozer and working it in with a speed tiller. He saw better germination, less wind erosion, and reduced wash on lupins, canola, barley, oats, and wheat. It's a one-off treatment when clay is available nearby.

Our soils are non wetting in that 4 to 5 inches of the topsoil. So we're just applying clay at 150 to 160 tonne to the hectare and just working it in with a speed tiller at 4 to 5 inches. Since we've put on clay, we don't have any more or less, don't have any blow, have a lot less wash from thunderstorms and our new just great germination. It's the biggest thing with getting crops out of the ground. We've got heaps more pasture. Look, putting on the clay is, well, we just call it a no brainer. If you're having issues with blow and non wetting, claying is a very good option. We're roughly 22 K's north of Badgingarra and we've got 10,000 acres in there. We grow lupins, canola, barley, oats, wheat, we grow them all. We just grow a bit of everything each year. The whole thing is quite expensive. We use a dozer contractor to push all our clay up. If you're going to muck around with a small spreader, I think you're probably just better off getting a contractor to do it. We can roughly do a hectare an hour. It all depends on the distance you've got to travel. So if it's fairly close, if you've got a 60 hectare paddock and the clay pits in the middle of the paddock, you could do a hectare an hour quite easily. It's not just the sand either, it's our good gravels, the gravels over clay that are non wetting as well. So we put clay on those gravels and the response is great claying is just a one off if you've got the right clay. The germination in our crops and the germination of our pastures is just like second to none. It's just heat spinners probably at least double Great results. Yep.
