The automatization is far from being the norm (if you mean autonomous tractor). Then automatization applies to both type of agriculture. But there how do I figure? Not sure to properly understand your question, because less works mean less labors. Automatized or not.
The parent just said "automated". Using a tractor driven by a person to till a field is a vast savings over using a horse or person, as was done previously.
Autonomous vehicles and AI have been vastly oversold as a mean or a source of automation. There's been a huge amount of automation through applying regular machines to things that were previously done by hand and that's still where most labor-saving improvements happen.
