Rolling is quick, especially with the largest roller, and doesn't burn much fuel. I always roll after seeding) will net you another 2.5%. Rolling after seeding (some say rolling before seeding works but then other say it doesn't and needs to be done after seeding not sure which is right. If you are harvesting a lot of land like you say then 2.5% over many acres/hectares adds up. I had a look through the Academy pages but can't see anything in there that helps answer the question. Not sure whether or not this gives the bonus to the radish or not but does radish even have a yield? I thought it was seperate from harvest crops and it's purpose was to increase the fertiliser stage, not be harvested and sold. You could do that before you drill the radish, i.e. I only grow grains so not sure of other crops but for me that means I would mulch (I personally don't mulch) the stubble that was left on the field. Not used this method so don't quote me but from what I understand you mulch (for +2.5% yield) what remains on the field after harvest.
