From what I read, the John Deere strike has nothing to do with rising food prices. It has more to do with the rising price and some places the short supply of deisel fuel, some truck stops limiting truckers to 60 gallon as to the distrabution of food and getting it to market. Which means higher transportations cost, food prices rise. Rising food prices probably has a lot to do with the nitrogen shortage for fertilizer. Which in turn means when fertilizer costs more so too does food.Farmers turn away from corn and wheat to soy beans and other crops that need and use less fertilizer.
To produce the nitrogen needed for fetilizer, coal and natural gas is needed which is also in short supply.
In short to use an old phrase, "Houston, we have a problem."
