I can tell you being a first time food plot planter that it is very important. I broadcast my lime first then tilled the soil. I then broadcast my plot mix seed. After that I broadcast some triple 13 fertilizer. Evidently the tracter tires R4's made the seed contact good. After a week I went to look at my plot and where the tire tracks were the plot looked great! Everywhere else didnt look so great. Now im on 4 weeks and you can definately see If I would have ran a cultipacker over it my plot would have turned out real nice. Dont get me wrong the other areas are growing but just not as well as where I drove the tractor over the seed. My next plot will be much better now that I have learned my lesson.
