Now, agriculture needs chemical fertilizer. What methods did ancient people use to improve the land?

We should all know that only fertile land can grow good food. Although barren land can also grow food, the effect is not very good. The land will also become barren, so people need to improve it. Now the most common way is to apply chemical fertilizer, so many people will ask, what methods did ancient people use to improve the land? Let Bian Xiao talk!

In fact, people living in rural areas should know that in the past few decades, when the peasant economy was still underdeveloped, few people used chemical fertilizers. But more is to use manure to fertilize. At that time, almost every household in the countryside had huts. In order to make the land fertile, farmers would pick the manure from the huts into the ground. If the land is used to grow vegetables, many people will bury the firewood ash burned at home in the soil, which can also improve the land. Nowadays, it is easier for people to cultivate the land and directly sprinkle fertilizer on the ground. Therefore, in ancient times, people also used animal manure to improve the land. In the spring ploughing season, this scene can still be seen in some rural areas, but it is becoming less and less. Due to the epidemic, Bian Xiao could not return to work at normal time. It's still at home, but now farmers don't improve the land in the traditional way, just fertilize it to make it fertile.

Of course, another way is to dig out the grass on the ridge with a hoe and bury it in the ground. Then the grass will ferment in the ground, and it can also improve the land and make it fertile. Farmers in ancient times were very clever, and of course this is also the way handed down by our ancestors. But with the development of science and technology and the improvement of farmers' economy, this method has been rarely used. Therefore, people nowadays are increasingly pursuing pure natural green food, because we all know that the current grain is basically grown by applying chemical fertilizers and pesticides.

The above is Bian Xiao's point of view. Do you still know how ancient farmers improved their land? Come and talk about your opinion in the comments section!
