Traveling through time and space and becoming a deposed prince, he just wants to survive!

Zhao County was the birthplace of the State of Zhao. Unfortunately, the State of Zhao was as complicated as a thousand Hamlets, which was equivalent to keeping the wealth of the descendants of the State of Zhao out of the country.

If these words had not been spoken by the prince Zhao Sheng, he would have been driven out of Zhao County by the Zhao clan long ago.

"I really want to hear Mr. Zhao's true words."

Such a major event has remained unnoticed for so many years. What kind of mystery is hidden in it?

"According to your old way of thinking, you plant in spring and harvest in autumn, then collect a small amount of taxes from people. However, even if you later collect more taxes, the total amount will remain the same, and there will not be any extra people for you to harvest."

Zhao Sheng almost said that they were harvesting leeks. In his eyes, these people in Zhao County were like mechanical development with nothing new to offer.

"Then... please give me your instructions, Master Zhao."

"In my opinion, after this spring, we should not plant rice in the soil, but soybeans instead, and we can plant three crops a year."

Soybeans are another name for soybeans. In short, they are soybeans. They don’t taste very good when cooked.

"Mr. Zhao, are you kidding me by doing this?"

"I'm doing this to change the soil structure in Zhao County. If we continue this for three years at most, and then plant rice again, the rice yield per mu in Zhao County will reach more than four shi."

Four shi is almost five hundred kilograms, which was considered a high yield at that time.

"Sir, can the problem be solved by switching to soybeans?" Zhao Changsheng still found it hard to believe.

"I guess you won't understand this secret even if I tell you, but since I'm doing this for the Zhao family, I'll tell you." Zhao Sheng picked up the teacup on the table and took a sip of water. At this time, Zhao Guangyi was also invited over.

"Our current soil contains too much alkaline substances, and there is no nitrogen, phosphorus, potassium, or organic fertilizer that the soil needs. Don't think that burning straw in the autumn is like farting. It will only make the soil more compacted and the nitrogen fertilizer in the soil disappear."

"I asked you to plant soybeans because the soybean root system has a special biological mold that can increase the nitrogen compounds in the soil. Secondly, the residue of soy products can be used as fertilizer to increase the nitrogen fertilizer in the land.

Of course, you can burn some excess straw, and in fact, the ash from your home stove is very good. Never burn it in the fields."

Zhao Guangyi, as the county magistrate, knew a thing or two about agriculture. He asked, "Wouldn't burning straw in the fields kill insects in the soil and increase its fertility?"

"Earthworms? You're talking about the bugs that eat crops, right? How many of these bugs have you seen causing damage in the spring? Most of them are in the fall. Many people think these bugs grow up during the Spring Festival and come out to cause damage in the fall."

"Actually, burning has only a few benefits. We're in the north, where pests are frozen to death in winter. That's the so-called auspicious snow heralds a good harvest. Southerners say burning has some merit, but for us northerners, that's pure bullshit."

Zhao Sheng's words made the two people with the surname Zhao lower their heads in shame.

"Don't take my words for granted, especially in northern China. Burning straw not only kills insects, but also turns the only nitrogen fertilizer in the soil into nitrogen oxides, which are particularly prone to corroding plant roots the following year."

"Also, nitrogen oxides, under alkaline conditions, will produce ammonium salts, which are toxic. If large amounts of ammonium salts enter water bodies, they may lead to eutrophication, posing a threat to the survival of fish and other aquatic organisms. They can also cause soil compaction."

Mr. Zhao talked a lot, but the two authoritative figures named Zhao didn't understand a word he said.

Finally, Zhao Changsheng said, "For years, the elders have said that burning straw in the fields in autumn will ensure a good harvest the following year. Yet, our annual yield in Zhao County remains so low."

"This is not entirely due to burning straw, but burning straw in the fields is the stupidest way. Burning straw mainly produces potassium fertilizer and nitrogen fertilizer, which requires a complex combustion technology so that the fertilizer produced can produce effective nitrogen fertilizer."

Seeing that the two were still confused, Zhao Sheng picked up his teacup and said, "Have a sip of tea first. There is a saying in agriculture that a flower in agriculture depends entirely on fertilizer. The quality of fertilizer determines the development of agriculture.

For example, if there is a slight excess of ammonium in our soil, if we grow crops like soybeans, peanuts, rice, and millet, they will all become toxic, but they won't kill people for the time being."

Zhao Guangyi finally couldn't help but ask, "Are all the food in the palace good varieties?"

Zhao Sheng glared at him fiercely, then said softly, "Everything looks the same when it grows. You won't know until you plant it. If you plant poisonous weeds in the land, the crops you grow within three years will all be poisonous. Can you tell?"

Zhao Changsheng laughed when he heard this and said, "I heard that the urine of people who take medicine can kill flowers and plants. I wonder if it's true."

"This is a metaphor. People who take medicine frequently will have toxins in their feces."

Zhao Sheng's words completely ended today's topic. That is, according to Zhao Sheng's opinion, the whole county began to plant soybeans.

Afterwards, Mr. Zhao wanted to develop the secondary and tertiary economies, and use soybeans to exchange for grain from surrounding counties, or he could contract technology, that is, the land that used to produce 200 kilograms of grain could be planted according to Zhao County's methods, and the extra grain would belong to Zhao County.

The news spread in Zhao County, and the people in the surrounding counties were furious, and the lazy people were unhappy.

"We have been burning in the fields for so many years, why are they saying we can't burn in the fields now?"

A passing farmer said to the lazy man, "We don't even have enough straw at home, and you guys are burning it directly in the fields. You don't even think it's a pity."

In ancient times, anyone who burned straw in the fields was considered lazy and disrespectful to the crops. Straw was very important to the people in ancient times, even as feed in winter. Otherwise, could the big guillotines in the homes of the past have been used to chop people?

So some people who don’t understand say that burning straw in the fields has been going on for thousands of years. Those who say this are basically ignorant or sent by enemy spies.

Mr. Zhao doesn't think too much about it. He now makes his own protein meat, tofu, bean sprouts and other foods, and sells them to the surrounding areas. All of them are done by people from his Shigang Village.

More and more refugees are coming to Shigang Village now, but Zhao Youfu is the only one who can decide which food can be sold. After getting the money, the village will deduct some of it as the village's provident fund in the future.

The provident fund in ancient times was different from the modern one, and was called variously, such as "public expenses", "public money", "charity money", "community money", etc. However, there was indeed a provident fund.

People of the time recorded that the public collection of money "was not much, but the emperor ordered that the remaining profits be collected, so that the prefectures and counties could do as they pleased. As for the military governors and other departments, there were also warehouses for supporting the people and preparing for the border, and they opened pawnshops and sold prepared medicines. They did everything they could to support the public envoys."

This shows that people had a preliminary understanding of reserve money very early on, and in the past, there was also such money in the countryside, which was specifically used for the elderly, the weak, the sick and the disabled.

However, such good qualities were forgotten by later generations, and people often asked for money from the public and were ridiculed as being nonsense.
