There were so many mines on Larisa Sysenko's small farm in Kamyanka in eastern Ukraine after the Russians were pushed out that she and her husband Viktor started demining it themselves -- with rakes.

Further along the front line at Korobchyne near Kharkiv, Mykola Pereverzev began clearing the fields with his farm machinery.

"My tractor was blown up three times. We had to get a new one. It was completely unrepairable. But we ended up clearing 200 hectares of minefields in two months," he said.

"Absolutely everyone demines by themselves," declared Igor Kniazev on his farm half an hour from Larisa's.

Ukraine is one of the great bread baskets of the world, its black earth so rich and fertile you want to scoop it up in your hands and smell it.

But that dark soil is now almost certainly the most mined in the world, experts told AFP.

More than three years of unrelenting artillery barrages -- the biggest since World War II -- have sown it with millions of tons of ordnance, much of it unexploded.

One in 10 shells fail to detonate, experts estimate, with as much as a third of North Korean ordnance fired by Russia failing to go off, the high explosives moulding where they fall.

Yet the drones which have revolutionised the way war is fought in Ukraine may also now become a game-changer in demining the country.

Ukraine itself and some of the more than 80 NGOs and commercial groups working there are already using them to speed the mammoth task of clearing the land, with the international community pledging a massive sum to the unprecedented effort.

But on the ground it is often the farmers themselves -- despite the dangers and official warnings -- who are pushing ahead on their own.

Like the Sysenkos.

They were among the first to return to the devastated village of Kamyanka, which was occupied by the Russian army from March to September 2022.

Two weeks after its recapture by Ukrainian soldiers, Larisa and Viktor went back to check their house and found it uninhabitable, without water or electricity.

So they let the winter pass and returned in March 2023 to clean up, first taking down the gallows Russian soldiers had set up in their yard.

And they began demining. With their rakes.

"There were a lot of mines and our guys (in the Ukrainian army) didn't have time to take care of us. So slowly we demined ourselves with rakes," said Larisa cheerily.

Boxes of Russian artillery shells are still stacked up in front of their house -- 152mm howitzer shells to be precise, said Viktor with a mischievous smile.

"I served in the artillery during Soviet times, so I know a bit," the 56-year-old added.

That summer a demining team from the Swiss FSD foundation arrived and unearthed 54 mines in the Sysenkos's field.

They were probably laid to protect a 2S3........
