Coming from ex-USSR… I’m used to unused fields. Nowadays situation is better. Where soil is best, all (most?) fields are used. But in other parts of the country unused fields are not uncommon.
It doesn’t help that we are getting only a fraction of EU farming subsidies. While fancy machinery cost the same as for western counterparts. So Netherlands with higher wages are outpricing our farmers :D
I think it’s matter of time when more and more of those deals will reach the tipping point. And after that it will be very hard to restore local agriculture.
