According to the data of USDA, more than 1/4 of global wheat exports come from Russia and Ukraine. The latter also supplies 16% of the global corn. The conflict between Russia and Ukraine has made the originally high international food prices worse. On the second day of Russian President Vladimir Putin's televised speech, the price of wheat futures in Chicago jumped by 6. 17%, showing the influence of Ukraine on international food prices.

In fact, agriculture has always been the economic pillar of Ukraine, and Ukraine is known as the "granary of Europe". When it comes to agriculture in Ukraine, we have to mention the local agricultural endowment: black soil. Black soil is called чернозём in Russian. It is one of the most fertile soils in the world because it is rich in black humus.

The northeast of China also belongs to the black soil area. In the words of local farmers, "chopsticks sprout as soon as they are inserted" in black soil. But the northeast is not the place with the most black soil, and the black soil is not a specialty of the northeast. The place with the most black soil in the world is Ukraine.

The distribution area of "black soil" in the world;

According to the report of the United States Department of Agriculture, there are three black soil areas in the world, namely the Northeast Plain of China, the Great Ukrainian Plain and the Mississippi River Plain of the United States. Among them, the black soil in the great plains of Ukraine is the most widely distributed, accounting for about 1/4 of the world.

More than 60% of Ukraine's territory is covered with black soil, so that the former Minister of Agriculture once proudly declared on Facebook that the area of black soil in Ukraine exceeds that in Britain.
