In Li Sheng's memory, the first thing that is most commonly used in later generations was ammonia.

In addition, there are all kinds of things, but in summary, they are not detached from ammonia, nitrogen, and ammonium ions and nitrate ions are the core.

"Oh? This..."

Li Er and others were stunned. Unexpectedly, there was still something behind this fertilizer?

Wei Zheng also frowned, but he understood it in his heart.

"It's worth it to be that fertilizer is so effective."

"I don't know how to refine this fertilizer? If so..."

Du Ruhui nodded,

"If it is difficult for the people to obtain, then things will be difficult..."

This is a very simple and clear economic account, just think about it.

Fertilizers can certainly increase the production of land significantly.

However, if the fertilizer on a mu of land is consistent, the grain obtained from increasing production can only be sold for 800 cents.

Then the question is, for the people, wouldn’t this use of fertilizers be a loss?

Then it’s better not to use it!

This is an extremely simple truth, and Li Er and others quickly turned the corner.

"Young Master, this fertilizer cannot be too expensive, if it is too expensive..."

Li Er and others frowned.

So Li Sheng couldn't help frowning.

"You guys... are they too stingy?"

“Although fertilizers are not easy to obtain.”

"But when factory-based production costs up to fifty cents per acre of land. I can't afford to pay this money. Do you still want to start a planting industry?"

Li Sheng thought it was outrageous!

Li Er and others were stunned.

I'll go, you've been talking for a long time and it's hard to get it, but it's only fifty cents?!

This is simply cheap, okay?

Too exaggerated!

"This... Isn't this a net profit of two or three chunks per acre of land?"

"Then...then, isn't this people..."

Wei Zheng and Du Ruhui said it was not easy to speak directly. The family could earn two or three stakes per acre of land, but this was two or three stakes!

There are all over the world!

At that time, I am afraid that the price of food will gradually become lower and lower.

At that time, the people will not only be able to get rid of famine forever, but also raise livestock with extra grain, and it is not impossible for every household to eat meat!

An unprecedented prosperous age appeared faintly before everyone's eyes...

A group of people looked at Li Sheng with their eyes straight, as if they had seen a god and a saint.

If you talk about the potatoes before, sweet potatoes can be considered auspicious.

Then 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 that the people and God will not let him go!

What is the ruler of the country?

That's it!...

...

Where did Li Sheng notice so much?

Go out for a walk.

I usually write and write questions by myself and review physics, chemistry and mathematics knowledge.

When you come out, you should naturally look at the mountains and maintain your retina.

Speaking of this fertilizer, it is not easy to make, and Li Sheng really wants to complain about it.

No matter which kind of fertilizer it is, it is ultimately the same - the nitrogen atom content must be high!

If the content of active ingredients is high, the fewer impurities, the better.

Of course, when nitrogen and ammonia fertilizer enters the land, there will naturally be more impurities, and it is not pure.

But that is after the nitrogen element has been solidified, and before that, it cannot be done casually. Preparation must be very demanding.

However, Li Sheng could not explain these truths to Li Er and the others.

...

After understanding the value of fertilizers, what Li Er cares about the most is...

"Then, young master, when can this fertilizer be built? "

"If construction starts one day earlier, it would be better for the people to improve their livelihoods as soon as possible!"

Li Er couldn't wait.

After hundreds of years from the Eastern Han Dynasty to the Wei, Jin, Southern and Northern Dynasties, the population of Shenzhou has decreased significantly from more than 60 million to the peak of the Western Han Dynasty.

By the Sui Dynasty, it had recovered a little, reaching more than 40 million. However, at the end of the Sui Dynasty, the heroes fought against each other and the world changed significantly, and the population is now only a pitiful millions...

This is really not Cao Cao's words, but some places are really slandered.

In Li Sheng's memory, it was also the beginning of Zhenguan that Li Er and others fought for their lives. After reaching the limit, they only recovered to more than 12 million in the thirteenth year of Zhenguan.

You can imagine what the situation was like in the second year of Zhenguan.

So how can you not be in a hurry if you tell him?

Li Er is not the kind of stupid emperor who talks about the people and doesn't know how to farm. He knows very well.

With this fertilizer, on the one hand, the yield per mu has increased significantly.

On the other hand, the farming time that people have to spend on acre of land has become less!

It takes less time on average, so you can reclaim more wasteland...

The national strength of the Tang Dynasty,

After a few years... Mom, I don’t dare to think too much!

I'm thinking too much and can't sleep anymore!

Li Sheng smiled.

"Old Li, aren't you anxious? You can't be anxious. You have to think about what the people have now? With sweet potatoes, potatoes, etc., and this curved plow... Although they are all superficial things, please pay attention to the influence."

"What do you rely on to hoard land in your family? Isn't it just that the people are poor and urgently use money and then buy the land for you. If they are all rich, where do you go to buy land?"

"At this time, fertilizer appeared again. This is a killing weapon. We can make it in the Tang Dynasty, but the Turks and Goguryeo people absolutely cannot make it."

"What can be predicted at that time is that every household will probably be rich. Not to mention eating, it is not difficult to raise a large amount of grain, raising pigs, cattle, mutton, and eating meat to exercise, or even raising horses and practicing martial arts."

Li Sheng said this.

Li Er was so anxious that Wei Zheng, Du Ruhui and others even looked even more blue.

Everyone was complaining. If Made had known that something would be bad, he would have to say that he was a wealthy family in Chang'an?

"No, young master, so I need to start fertilizer immediately!"

"ah?"

Li Sheng looked at Li Er in confusion when he heard this.

"Old Li, your family is not a rich man from Chang'an? Why... are you hiding something from me?"

After Li Sheng asked this, even if Wei Zheng and his team were anxious to break through their foreheads, they could only smile first, "Why, young master, I am not the one who takes advantage of the disaster to hoard the fields. You can't look down on me!"

"Then you..."

Du Ruhui reacted quickly and immediately smiled and said,

"Young Master, have you forgotten 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, and you can use it at any time!"

Li Sheng suddenly realized.

He suddenly laughed.

"Oh... you guys, I understand."

Li Sheng was very happy. These wealthy families in Chang'an... are so progressive!
