BEIJING—China’s COVID-19 curbs are disrupting the supply of fertilizer to the country’s northeastern bread basket just a month away from spring planting, threatening this year’s corn and soybean crops if not resolved soon.
Farmers typically have fertilizer prepared in early April before applying to fields later in the month during planting. But China’s worst outbreak of COVID-19 since the pandemic began two years ago have triggered strict controls on movement of people and goods, sharply slowing deliveries.
