Due to the Russian invasion, Ukraine, a major global producer of agricultural products, has banned fertilizer exports, according to the agriculture ministry on Saturday.

Ukraine has already banned the export of some agricultural commodities and implemented licenses for its main export commodities, wheat, corn, and sunflower oil.

“The cabinet of ministers is introducing a zero quota for the export of mineral fertilizers, which is effectively a ban on fertilizer exports from Ukraine,” the ministry said in a statement.

It said the ban would help “to maintain balance in the domestic market” and applied to nitrogen, phosphorus, potassium and complex fertilisers.

Ukraine traditionally starts spring field work in late February or in March. Farmers say they will start sowing in safe areas as soon as they can.

Ukraine’s President Volodymyr Zelenskiy said on Friday the country must sow as many crops as possible this spring, despite the Russian invasion.

The country’s agriculture producers’ union said this week farmers were likely to reduce areas sown to sunseed, rapeseed and corn this year, replacing them with cereals – buckwheat, oats and millet.

Ukraine, the world’s largest exporter of sunflower oil, had forecast before the invasion that it could export more than 60 million tonnes of grain, including 33 million tonnes of corn and 23 million tonnes of wheat, in the 2021/22 July-June season.

The agriculture ministry said Ukraine had exported 43 million tonnes of various grains in the 2021/22 season as of Feb. 23, the day before the invasion.
