There are many agricultural "experts" that argue that plowing is not necessary and damages soil structure - and causes errosion.
I'm not an expert though. I see it like this. You start out with a field full of some sort of residue on top - old crops, dead grass, manure, etc. And, the ground is often hard. You plow it - and it gets rolled over - although the results can vary from moldboard to chisel plows. The organic stuff on top gets sent down a little deeper where new crops can better use it. After plowing, and it dries a little, you can disk it to make the soil fine engough to allow seeds to be planted and later sprout.

An option that used to be popular in my area of hard-pan soil New York - was no-till seeding. The County Ag. department was pushing it for awhile in attempts to stop plowing and limit errosion. Doing so takes a special "no-till" seeder for most crops and also takes a lot of chemcials. Some "experts" finally decided it was not cost effective - and perhaps did more damage with all the chemicals needed.
Most experiments with no-till in my area was with corn and the results were not very good.
Somebody else might give you different reasons for plowing, or perhaps for not plowing.
