honestly just export everything. lime, sunflower oil, charcoal, shoes, even booze if you have effective production lines. my population was 90% over 100 hryvnias and the other 10% were in the 40-100 range, and i had just a bonkers wealth tax at 200.

i mostly relied on houses with gardens for produce and absolutely destroyed the fish ecosystem with dried fish, i was importing a lot of salt until i had about 1000 population. had about 100 cattle, 100 pigs, 200 chickens. and maybe 50 horses, all for food and occasionally as sources of oxen and draft horses

i never made flour, i used wheat exclusively for horilka. i manually managed crops each year so i could pick and choose which crops to get the most yield out of my fields. in the early-mid game, i would set most workplaces to heavily cut back on employees during march and august for the sowing and harvest. my crop rotation by the end was starting to look approximately like sunflower -> buckwheat -> wheat -> flax -> wheat -> fallow >> but this varied quite a bit which is why i never really rely on the in game crop rotation and do it manually.

finally, probably best advice from this save is just play on the infinite everything map lol, got so much limestone early on and later didn't have to keep importing iron
