Thomas ran over the field six times with the disc and we still had some dead grass blades on the surface, as you noticed. Normally it is a one or two pass exercise to get the top turned under, but we've had a real dry spell, with high heat, so our clay soil is baked and stubborn to disc. Further, the vegetation was really thick to start with, so burying it all was going to be a tough task. But overall, the field is a dirt top. I think the tractor in the picture was parked in the "grassiest" area. We do have a 6' disc that is much more aggressive and does a better job getting deep, but the time it takes doesn't mesh well with a weekend-only crew. That and wheat is forgiving to plant. The heavy rains we get today will probably negate the need to cultipack. We simply ran out of time to do it all in one weekend. Hopefully the seed doesn't wash away.
I'm always amazed at the differences in agriculture practices. Certainly, things are significantly different across the country. But even a few counties away I see more turned fields and less no-till farming. No-till has been the method of choice for years, but from what I gather its changing. Some farmers are going back to burning and plowing.
