The new wave in farming seems to be Minimum Tillage or MinTill. This explains why you don't see fields being ploughed so much these days.
The idea is to minimise the disturbance to the top layer of the soil, and thereby retain most of the nutrients where they are needed, so fields just get roughed up after harvest, then they send in the giant seed drill.
These giant octopus like implements scrape and clatter across the fields at high speed putting seed into the soil and covering it over in a precise and controlled manner. Some things don't change though: You still get the seagulls following the tractor.
