Each farm is different - in fact within a field there is enough variation that the best management is not the same across the whole. Thus you cannot subsidies any one practice.
What the subsidies do is subsidize insurance. Buy insurance and if you have a crop failure you get paid as if you had the average yield over the past 10 years. However your average goes down as well for the next failure so better not have too many bad years in a row.
Organic despite the name is not the best thing for the environment. Some of it is, that quickly is normal farming. What is left is not using safe chemicals, instead using much more harmful - but natural - ones, or tillage to control weeds. (Note that this article is pushing no-till which is conventional farming today)
