I was watching short videos and was seen by ancient people

Chapter 280 Necessary for Time Travel—Making Soil Fertilizer ()

[If you travel back to ancient times, you must understand the key position of food.

Society is essentially a food war. If you control the food, you will have the initiative.

At that time, food production was actually quite simple, in part because planting techniques were relatively primitive and seed and fertilizer technologies were immature.

If you are lucky enough to travel through time and want to quickly increase food production, chemical fertilizers are a breakthrough.

However, it should be noted that ancient technology cannot produce fertilizers, and even in modern times, most countries still need to import some fertilizers.

However, this does not mean that it is completely impossible to make fertilizer. You can try making soil fertilizer.

Next, I will teach you several methods of making soil fertilizer:

Soil amine fertilizer: Take 50 kilograms of fresh cow dung, 50 grams of soybean flour, and 5 kilograms of plaster of paris powder. After mixing according to this ratio, seal it in an earth kiln for 3 days. When fertilizing, add three times the weight of water.

Earth sulfur powder: Take 50 kilograms of human feces, 5 kilograms of plaster of paris, and 25 kilograms of water. Mix them in the same proportion and seal them in an earth kiln. Fertilizer can be applied after 10 days.

Native nitrogen-phosphorus compound fertilizer: Animal bones are processed into bone meal and used as base fertilizer. The production of plaster of paris is relatively simple. You only need to crush the gypsum ore and heat it to 150 degrees, and then dehydrate it.

In addition to these chemical fertilizers, we can also make organic fertilizers. Collect all available organic matter, such as straw, fallen leaves, human and animal manure, etc., and mix it with cover such as straw.

Turn the pile every three or four weeks and it will be ready for use in three months.

In addition, plant ash can be used as potassium fertilizer, and bird droppings are good phosphate fertilizers.

Crop rotation is another method to increase yields. For example, soybeans and wheat are cropped once a year. This kind of single-crop rotation between years can be carried out under multi-ripening conditions throughout the year.

Properly arranging crop rotation can not only prevent and control pests and diseases, regulate soil fertility, but also make balanced use of soil nutrients.

With this knowledge, you can not only solve the problem of food shortage, but also make the people convinced of you, and even enshrine you as Shennong after your death.

So traveling back in time to ancient times, making soil fertilizer is the only way for you. 】

People from all dynasties were shocked when they saw the video on the sky screen.

They always thought that the food yields in later generations were so high because their seeds were better, or they planted high-yielding crops! However, what they didn't expect was that there would be such a thing as chemical fertilizer in later generations!

And judging from the introduction on the marquee, not all countries can master the technology of making chemical fertilizers. Most countries are not completely self-sufficient!

This made them a little worried. Will China be like this in future generations?

They have experienced hunger, but do they know what the lives of the people will be like if there is not enough food?

But when they thought about the prosperous world of later generations, they felt that their worries were unnecessary.

Then they saw the introduction on the marquee of how to make various soil fertilizers, and they quickly memorized it silently!

This is a windfall for them. With these fertilizers, they believe they will be able to grow high-yield food in the future!

Landowners from various dynasties were deceived when they saw the message on the sky screen!

They did not expect that future generations would have such a murderous weapon that would make the originally barren land fertile!

It can also make food more productive so that people no longer endure the pain of hunger.

And compared to the steam engine, the method of making soil fertilizer on this canopy is simpler, which is simply the favorite of landowners like them!

So they gave orders to their family members, asking them to make the soil fertilizer mentioned on the canopy, and then test it in the fields to see if it could increase grain yields! Scholars from all dynasties have gone crazy with joy during this period. They have become the most respected people at this time!

Compared with those ordinary people who can only silently remember the method of making soil fertilizer on the sky screen in their minds, they can write it on paper with a pen to prevent themselves from forgetting the method of making soil fertilizer.

Moreover, the method of making soil fertilizer that they wrote down on the paper has become the favorite of the people, and countless people come to ask for it with money!

Qin Dynasty.

Qin Shihuang watched the video on the sky screen and was shocked!

He didn't expect that there was so much emphasis on growing crops.

You must know that in his era, people were more engaged in slash-and-burn farming.

As for fertilizing food, except for a few people, no one does this!

Moreover, in their era, all organic fertilizers were accumulated. Although the plants could absorb the fertilizer, the effect was very slow!

It was precisely because of this video that Qin Shihuang realized that there are so many things to pay attention to in growing food.

If Da Qin wants to have a high yield of food, it needs to do what the sky says!

And the so-called agricultural technology also needs someone to study.

Thinking of this, Qin Shihuang thought of the peasant children who taught knowledge at Baijia College.

Although they are a small sect in Baijia College, they have a lot of agricultural knowledge.

It would be perfect if they studied agriculture.

So Qin Shihuang summoned the leader of the farmer and ordered him to study how to plant crops to achieve higher yields and how to prevent and control crop diseases!

Even in order to facilitate their research, the farmers were separated from the Baijia College and established a separate college like the Mo family!

When the leader of the farm family heard Qin Shihuang's order, he was very excited!

Although his sect has existed since the Spring and Autumn Period and the Warring States Period, it has not received much attention.

The ideas of their school and various agricultural planting methods have not been carried forward. Now that Qin Shihuang attaches great importance to them, they have more illusions about the future!

But they knew that if they failed to meet Qin Shihuang's requirements, the final result would be to be knocked down from the clouds!

The leader of the farmer didn't care about this worst knot. In his opinion, Tianmu had given them a lot of knowledge and even taught them how to make soil fertilizer.

If they can't manage agriculture well in the future, how can they have the face to face their ancestors!

But their first priority now is to test whether the soil fertilizer on the sky screen has any effect?

If it works, how should we solve it? It doesn’t work anymore, how to solve it?

The other sects of Baijia Academy were filled with jealousy when they heard that Qin Shihuang had also established a separate academy for Nongjia!

The Mohist school set up a separate college, which in their view was their own ability.

They knew how difficult it was for the children of the Mohist family after Tianmu appeared, and they also knew deeply the changes these children of the Mohist family had made to Great Qin!

But what did this farmer's boy do? He was also taken seriously by Qin Shihuang!

Even if the sky says that food is the foundation of the country, in their view, Qin Shihuang's rewards to farmers are too generous!

However, he thought of the Spring and Autumn Period and the Warring States Period, when they were silent due to the suffering of hunger due to lack of food.

After all, food is the foundation of the country, and they do not have the ability to study agriculture. There is no reason to oppose the establishment of independent colleges by farmers just because they are small sects.

What's more, it was Qin Shihuang who set up a separate college for farmers, and they didn't have the courage to oppose it!

However, they also discovered the pattern and understood that only if their school was useful to the Qin Dynasty, would it be reused by Qin Shihuang and allow his school to establish a separate college.

So they began to work hard, hoping that one day their school would be able to establish a separate college.
