How does the transmission from energy to agricultural Bulk Commodities actually work?

How does the transmission from energy to agricultural Bulk Commodities actually work?
The chain runs from crude oil to chemicals to fertilizers to food. Oil sets the cost floor for petrochemical inputs, which feed into fertilizer and pesticide production. When energy spikes, farming costs rise with a lag, and grain prices eventually follow. This cycle is amplified when major grain-producing regions are disrupted by conflict. Ukraine and parts of the Middle East are both affected. The market is now watching whether fertilizer prices confirm the next leg. If they do, agricultural Bulk Commodities could become the third wave after metals and energy.
