"It's noisy here. But life goes on. We had a spot of rain earlier, so we've been waiting for the wheat to dry. My son is serving in the army near here. I'm hoping our lads are going to start counter-attacking soon and push the Russians back," he said, on a brief break from work.
"They fly like that almost every day. It gets lively here. The pilots do their job. We do ours. Everyone is busy. But their work is harder," he said.
Kurinniy's farm, spread over two picturesque, rolling valleys, has more than 3,400 hectares (8,400 acres) of wheat and sunflower seeds, and cattle too. But he closed the livestock business down after rockets hit a cattle shed, killing more than 20 animals. Another rocket missed the farm offices by a few metres, shattering windows.
"It's very dangerous, of course. But we're continuing. Our major concern is that the price we receive for our products is lower than usual. Last year, we sold wheat for about $300 (£250) a tonne. Now it's $100. And the cost of fuel has risen threefold.
"Then you have to add in fertilisers, seeds, pesticides, taxes, wages. So this year, we're likely to make no profits. And at any moment, we can be bombarded and everything will burn," he said, flicking through videos on his mobile phone that showed one of his fields on fire after a recent missile strike.
"We usually export 90% of our crops. We need this blockade to be lifted. But not at any price. There should be normal, civilised business relations. Not business combined with the use of threats and violence - as often happens with Russia. It should not be like that in the modern world," he said, angrily accusing Mr Putin of turning Russians into "zombies".
