BEIJING/SINGAPORE: Farmers around the world may be switching to less nutrient-hungry crops as the Iran war hits the supply of fertilisers, but in China, they're sitting pretty with plenty of stock thanks to the country's rather unique reliance on coal to produce urea. However, some analysts say China may not allow exports of urea - the most widely used fertiliser globally - after spring planting as it normally does, as that could drive up local prices. Beijing typically waits to see if there is a surplus in May before assessing how much can be shipped abroad.
