Some experts say that farmyard manure is harmful to irrigating crops, so farmers are not advised to farm with farmyard manure. what do you think?

Remember growing vegetables at home when I was a child. When I need water, my mother will take me to the vegetable field with a small bucket of excrement and urine in the septic tank at home. Then she asked me to add excrement and urine while watering, and told me that the vegetables would grow better without chemical fertilizer in the future. You knew then? Fat water doesn't flow to outsiders? You can try to go home if you pee, what's the name? Save it for watering the ground? Now my mother takes it out as a joke and tells it to my daughter.

In China's rural areas, the habit of fertilizing fields with farmyard manure has been used since ancient times. According to the old man, there was little or no chemical fertilizer in the past. In order to make crops yield high, farmers will raise several pigs at home, and then vigorously add straw to the pigsty, so that pig manure and urine will be good fertilizers after straw fermentation. When farming, they will pull the land into the field in advance and then lay it flat, so that they can plow the land.

For the topic that some experts say that farmyard manure is harmful to crops, the author inquired about the relevant content. This source should be that the remarks of Academician Ceng Yi, an academician of China Academy of Sciences, were taken out of context and misunderstood by some media.

This sentence was said by Academician Zeng when he participated in the column of Academician Time. Academician Zeng's original intention is not to prohibit farmers from using farmyard manure, but because he is an expert in virology, and feces have the risk of spreading hand, foot and mouth disease in children. Everyone who has children at home knows that hand, foot and mouth disease in children is still quite serious, and it is prevalent every year, and it is also an important disease that plagues parents. If the hand-foot-mouth disease virus is carried in feces and urine and then used to water crops, the virus may pollute vegetables and fruits, and if it is not cleaned before eating, it may lead to virus infection.

In addition, Academician Zeng said that manure should not be used to water crops, that is to say, fresh water should not be used, but there is no problem with fermentation. Just like the septic tank where rural families transform toilets, the feces in it will be killed by fermentation viruses, and it is no problem to water crops with feces.

Although some experts can't understand what farmers say, most of the time experts are reasonable and very strict. I hope the media will not misunderstand. Hope farmers' friends can see it? Expert? Just a look of disgust, there is really no expert life.
