The 62-year-old former Top Gear presenter took over control of the land in the Cotswolds he renamed as Diddly Squat Farm in 2019, when the local farmer who previously ran the site retired.
The Prime Video series Clarkson's Farm recounts his attempts to get to grips with farming, but the weather has provided a stumbling block for him this week as he aimed to harvest his barley crop.
"F***etty f***. Had to stop harvesting because of, and I’m not making this up, the fire risk," he wrote to his 7.8 million followers.
In response to a fan who asked what could cause the fire, Clarkson wrote that "any damn thing" could cause a blaze amid the dry conditions, including "a bit of litter, a spark from the combine, a fag end, a careless rambler".
He also confirmed that filming recently completed on the second series of Clarkson's Farm, which will air on the streaming service later this year.
One social media user quizzed Clarkson about his climate change skepticism, suggesting that he should trade in his Range Rover for an electric car or a hybrid.
The presenter responded: "Now that’s interesting. What’s more eco? A 17 year old Range Rover or a brand new electric car?"
Ah now that’s interesting. What’s more eco? A 17 year old Range Rover or a brand new electric car?

In July, Clarkson was one of several famous faces who has criticised the reporting of Britain's unusually hot summer.
"It’s very hot in the south of France but so far as I know, there’s no DefCon 8 level 3 killer death heatwave warning in place," he said.
He later revealed that one of his pigs died due to the weather conditions.
Clarkson is also facing an investigation by West Oxfordshire District Council in relation to the restaurant he recently opened on the farm.
He had previously been refused permission to convert a lambing shed into a restaurant, but said he had found a "loophole" which would allow him to convert a separate building without permission.
