Just picked up on the comment about input supply and how it compares with the Ukraine.
It is probably a little different here if you happen to be in the right place. We are not.
Seeds I am looking to bring in from Germany/Austria (thankfully I have good contacts in the seeds business). I have tried local suppliers and they are a disaster. Parts are a constant problem and they mainly have to be brought in. About the only things we source through the normal channels are for out Greggoirre Besson ploughs and then do not ask for parts for the skimmers, they are still a novelty here. We work closely with a Dutch friend and he is now the importer for much of the kit we own - we provide demo equipment. Amazingly it includes some pretty good brands who have failed ot get into the market, probably because they are expensive and local importers want to sell at full list prices! With fuel I need to install a proper tank and I expect that will mean loads of paperwork.
Pretty well everything has to be imported. It certainly puts an emphasis on self-sufficiency and having a good mechanic and workshop. Thankfully we now have the latter.
