The cost of fertilisers has rocketed.
Minimum wage has risen. Employer NI contributions have risen.
Water for crops costs money. When water reserves are low, water has to be trucked around the country. More expense.
Climate change is hitting the whole of Europe. Floods, droughts, heat, have reduced cropping. But the amount and cost of machines, labour, fuel, stock feed, fertilisers , irrigation hasn't reduced . So it costs farmers MORE to produce LESS.
Fewer apples, less wheat, means buyers compete to buy them; so supermarkets are then paying more for basic products. Not surprising we pay higher costs.
You aint seen nothing yet. Farming in UK is in big trouble; producers of meat, eggs, dairy are struggling to survive. If they go under and we have to import more meat, eggs, dairy, grain, we've lost UK control of production , health and welfare standards entirely. Plus, we'll be paying the cost of freighting those basics from abroad.
Farmers world wide are facing the same problems, costs of fertiliser, loss of grazing, climate change.
