In rural areas in North Korea, crop yields are very low due to the lack of agricultural production materials such as pesticides and fertilizers. Once chatting with a North Korean citizen, I said that China’s rice output can now reach 800 kilograms per mu. He was very surprised and said it was impossible.
In winter, when walking in rural areas of North Korea, you can often see North Korean farmers digging mud in the river. Why do North Korean farmers dig in the river in winter? Observe carefully and you will find that after they dug the river mud, they will use trucks and other transportation tools to transport the river mud to the farmland.
Later, a friend told me that the reason why North Korean farmers dig river mud is because of the lack of chemical fertilizers. River mud can be used as fertilizer. After the winter, spread a layer of river mud on the farmland, and the land will be much fertile in the coming year.
I can't help but sigh, although this production method is very primitive, although the yield is not high, the crops produced are absolutely natural and organic food.
Compared with China, people's material life is greatly enriched, but because of food safety, people don't always eat so assured.
