It has become more expensive to run a farm.
The meat and grain farmer Tina Rudolphson in Örsundsbro, 20 km north of Enköping, uses her diesel tractor for almost everything in agriculture.
Every year she disposes of 20-25 thousand liters of diesel in her farm.
If this year's price increase is SEK 4 per liter, she will have to pay more than SEK 80,000 more each year.
In order for farmers not to go back every month, they have to sell the food more expensively.
So the food must cost more for the consumer, thinks the Swedish Farmers' Association, where Tina Rudolphson is elected representative.
Economist: Prices will rise
The trade association Livsmedelsföretagen represents the producers, ie those who buy Tina Rudolphson's harvest and sell it on to the grocery trade.
They also note that food must become more expensive to compensate for farmers' increased spending.
Farmers will now start selling this year's harvest, and Livsmedelsföretagen believes that the price increase will be visible in stores until the turn of the year, perhaps already this autumn.
- I do not want to say how many percent more expensive, but there is no doubt that we will see an increase, says Carl Eckerdal, chief economist at Livsmedelsföretagen.
The increase in agricultural expenditure is not just due to the rise in oil prices.
The price of manure, feed and transport has also increased as fuels have become more expensive.
It affects all stages of food production, not least farmers.
- I do not have such large margins, so it does not have to be very expensive for it to feel, says Tina Rudolphson.
