I have already posted these before but I figured I might as well post some again to keep the thread going a little longer. I will also try to summarize the local farming practices here that cover most operations nearby.
After harvest is over we decide what type of tillage will need to be done to the wheat stubble, if the crop is light without much residue we just chisel without doing anything to the stubble. If it is heavy and we still want to chisel then we try to roll it once or twice on a dry afternoon. A few neighbors will heavy harrow the stubble instead of roll and in areas without as many rocks such as the palouse and further down the ridge from here they will often use a flail or mower on the heavy straw. All of these operations are best done when it is dry soon after harvest.
We generally roll wheat stubble with the 1155 because of its faster speed.
If we decide we want to moldboard plow the stubble instead of chisel and do it dry to kill perennial weeds then we also do that soon after harvest. Only a couple guys around here do the plowing early.
Once that is done we focus on getting ready to seed, that often means just disking the weed patches and smoothing them out and spreading residue. On canola stubble and some other neighbors plant winter wheat on spring cereals that ground gets tillage of some sort usually though a few do no-till. Many other guys near here work all the legume stubble with a cultivator once or twice and getting into the deeper soil areas toward the palouse they often put fertilizer on before seeding.
By late Sept and early Oct. the winter wheat seeding is going strong, we put on phosphate fertilizer with the seed. We always pull the drills in the fall with the D4D.
After fall seeding, tillage is done on the rest of the ground going into spring crop. D6C does most of the heavy work in the fall.
On the ground that was rolled we end up having to go around and round the field the same way as the roller for it to work right and then work the corners out, goal is to get the residue flat and mixed in with the soil rather than all still standing.
On spring wheat stubble and the other that is not rolled we prefer to chisel back and forth crossways and on the contour when possible.
If the residue it heavy we usually try to harrow the chiseled ground in the fall to help try to grind the straw up a bit and smooth the ground out. Some guys have harrows on the back of their chisels but we havent gotten that to work well.
We also do some spraying in the fall on winter crops if there are weeds present to prevent disease over the long winter under the snow or in the wet.
