2021 AD–2022 AD
Fertilizer-price and supply-chain shock
Food & agriculture · Technology · Agricultura
During 2021–2022, higher energy and gas prices, supply-chain disruptions, and trade restrictions raised fertiliser prices and reduced affordability for many farmers. The episode made visible that farm output depends on nutrient, energy, logistics, and finance markets. It does not establish a uniform decline in use or yields, because responses varied by country, crop, and season.
