How can farmers reduce soil compaction when using heavy machinery?

I was actually learning about pressure in school the other day and I think I have a pretty decent answer. The soil will compact because of the pressure applied by the vehicle. The formula is Pressure = Force (measured in newtons [there a 9.8 newtons in a kilogram]) divide area (measured in meters squared). There 's nothing you can do about the force but you can do something about the area. To increase the area you can really only do two things: 1. get a larger (wider) set of tires to decrease the pressure each one displaces 2. spread out the tires more (by this I mean instead of having the tires only 2 meters apart have them 4 meters apart) this will increase the total area and decrease the overall pressure. This is all the information I have so hope it helps and byee 8)
