In Li Sheng's memory, the most commonly used chemical fertilizer in later generations was ammonia.
In addition, there are various kinds, but in summary, it is not free from ammonia, nitrate and other substances, ammonium ions and nitrate ions are the core.
"Oh? This..."
Li Er and others were startled. They didn't expect that there was an explanation behind this fertilizer?
Wei Zheng also frowned, but he understood in his heart.
"Fertilizer is so effective, so it should be paid a lot of money."
"I wonder how to refine this fertilizer? What if..."
Du Ruhui also nodded,
"If it is difficult for the people to obtain it, then things will be difficult to handle..."
This is a very simple and clear economic account, you will know it when you think about it.
Chemical fertilizers can certainly increase land production significantly.
However, if one acre of land uses the same amount of chemical fertilizer, the grain gained from increasing production can only be sold for 800 cash.
Then the question arises. For the common people, if they use chemical fertilizers... won't they have to lose money?
Then it’s better not to use it!
This is an extremely simple truth, and Li Er and others quickly turned around this corner.
"Sir, this fertilizer can't be too expensive. If it's too expensive..."
Li Er and others frowned.
So Li Sheng couldn't help but frown.
"Are you... too stingy?"
"Fertilizer is not easy to come by."
"But to produce it in a factory, the cost is up to 50 cents per acre. You can't afford this money, so you still want to engage in farming?"
Li Sheng thought it was outrageous!
Li Er and others were stunned.
Let me go, you’ve been talking about it for a long time and it’s not easy to get, but in the end it’s only fifty coins?!
This is so damn cheap!
too exaggerated!
"This...isn't it true that every household can make a net profit of two or three thousand yuan per acre of land??"
"Then...then aren't these people..."
Wei Zheng and Du Ruhui said directly that it was unfavorable. A family can harvest two or three more guan per acre of land. This is two or three guan!
Available all over the world!
By that time, I am afraid that food prices will gradually get lower and lower.
At that time, people are afraid that not only will they be able to say goodbye to famine, but they will also be able to use the extra grain to feed livestock, and it will not be impossible for every household to eat meat!
An unprecedented prosperous age looms in front of everyone's eyes...
A group of people looked at Li Sheng with straight eyes, as if they were seeing a god or a saint.
If we talk about potatoes before, sweet potatoes can also be considered auspicious.
So now this fertilizer is a real holy object!
Li Sheng?
Li Sheng!
At this moment, Li Er was finally completely sure.
If I don't make Li Sheng the emperor, I'm afraid the people and God won't be able to let me go!
What is the Lord of the Country?
This is!……
…
How could Li Sheng notice so much?
Go out for a walk.
I usually write my own questions and review my physical, chemical and mathematical knowledge.
When you come out, you should naturally look at the mountain scenery more and take care of your retinas.
Speaking of this fertilizer, it is not easy to make, and Li Sheng really wants to complain about it.
No matter which kind of chemical fertilizer is used, the final analysis is the same - the concentration of nitrogen atoms must be high!
The content of active ingredients must be high, so naturally the fewer impurities, the better.
Of course, when nitrogen and ammonia fertilizer enters the soil, there will naturally be more impurities, and it cannot be said to be pure.
But that is after the nitrogen element has been solidified, but before that, it cannot be done casually, and the preparation must be very demanding.
But Li Sheng couldn't explain these principles to Li Er and the others.
…
After understanding the value of chemical fertilizers, Li Er is most concerned about...
"So, Master, this fertilizer... when can we start building a fertilizer factory?"
"If construction had started earlier, people would have been able to improve their livelihood earlier!"
Li Er simply couldn't wait.
After hundreds of years from the Eastern Han Dynasty to the Wei, Jin, Southern and Northern Dynasties, the population of China has dropped significantly from the peak of more than 60 million in the Western Han Dynasty.
By the Sui Dynasty, the population had somewhat recovered and reached more than 40 million. However, at the end of the Sui Dynasty, when the heroes fought for world reform, the population was greatly reduced. Now the population is only a pitiful few million...
Cao Cao's words of "shengminbaiyiyiyiyi" are really not what Cao Cao said. Some places were really beaten to nothing.
In Li Sheng's memory, it was also the beginning of Zhenguan that Li Er and others worked hard for their lives. After operating to the limit, it was not until the thirteenth year of Zhenguan that the amount was restored to more than 12 million.
One can imagine what the situation was like in the second year of Zhenguan.
So how can you ask him not to be anxious?
Li Er is not the kind of naive emperor who talks about the common people, but actually doesn’t understand farming at all. He knows very well,
With this chemical fertilizer, on the one hand, the yield per mu has increased significantly;
On the other hand, the time people have to spend cultivating an acre of land has become less!
With less time spent on average, more wasteland can be reclaimed...
The national power of the Tang Dynasty,
After a few years... Oh my god, I don’t dare to think too much!
I won’t be able to sleep again if I think too much!
Li Sheng chuckled.
"Old Li, are you in a hurry? You can't rush this matter. You have to think about it, what do the people have now? They have sweet potatoes, potatoes and the like, and this curved shaft plow... although they are all superficial.
Things, but you should pay attention to the impact."
"What do you rely on for hoarding land? Isn't it just that when people are poor and need money urgently, they buy the land from you? If they are all rich, where will you buy the land?"
"At this time, chemical fertilizers appeared again. This is a big killer. We in the Tang Dynasty can make it, but the Turks and Goguryeo people will definitely not be able to make it."
"What can be foreseen by that time is that one by one, every household will be very rich. Not to mention eating, it will not be difficult to allocate a large amount of food to raise pigs, cattle and sheep to eat meat and keep fit, and even to raise horses and practice martial arts."
Li Sheng said this.
Li Er was almost dying of anxiety, and Wei Zheng, Du Ruhui and others' faces turned blue.
Everyone was complaining in their hearts. Madu had known better than to make something up. He had to say that he was a rich man from Chang'an?
"No, sir, that's why we need to make fertilizer immediately!"
"ah?"
Li Sheng glanced at Li Er doubtfully after hearing this.
"Lao Li, your family is not a rich person from Chang'an? Why...are you hiding something from me?"
When Li Sheng asked, even though Wei Zheng and the others were so anxious that their high blood pressure was about to break through their foreheads, they could only smile and said, "Sir, we are not people who take advantage of disasters to hoard fields. You can't look down on me!"
"That you……"
Du Ruhui reacted quickly and immediately said with a smile,
"Have you forgotten about the paper factory a few days ago? Lao Li and I have made a lot of money. Even you have 40,000 to 50,000 taels of silver in your account, which you can use at any time!"
Li Sheng was stunned.
I laughed immediately.
"Oh... you are all one by one, I understand."
Li Sheng was very happy. These wealthy households in Chang'an were so progressive!
