Starting from the world of martial arts

What is it like to communicate with two great powers. It's like devouring the starry sky world, you are a star-level or universe-level warrior, and you meet a universe lord, and the two sides have almost no intersection at all.

Even the direct descendants of those Venerable Universes are rarely seen.

People who have reached this realm are also top-level powerhouses in the entire devouring starry sky, and they are the overlords of the universe.

Standing below the pinnacle of the universe, only the top human beings can surpass these.

So a small cosmic level has nothing to communicate with such a strong man.

But right now, Su Fan was communicating with Dayu and Zhen Yuanzi. Of course, the two seemed to know that there was a big gap between the two sides.

So when communicating, they deliberately took care of Su Fan, and the communication was mainly based on his topics.

What Dayu talked about was some medical skills and some related things about the farm.

Su Fan also understood that when Dayu came here, he brought out some knowledge systems.

Naturally, he did not hide anything from Dayu Su Fan, after all, the other party was the Human Emperor, the pillar of the human race.

What is Su Fan, the contact talent of the human race.

But he also understood that Dayu's arrival was to protect him in secret.

To be honest, Su Fan's heart is warm, and a quasi-holy-level powerhouse protects him, which shows that Huoyundong attaches great importance to him.

So he also said some of the content behind the farming, one by one.

Before farming, he only took out the fertilizer part, although it has increased the yield per mu of the field a lot.

However, there is still a big difference from the yield per mu of later generations.

Even with the use of new fertilizer technology today, the yield per mu is only equivalent to more than 250 catties in later generations.

You must know that the area of ​​one mu of Daqin at this moment is one and a half times larger than that of later generations.

The yield of wheat in the later generations reached about seven or eight hundred catties per mu, which was only one-third and one-fourth of the later generations.

The difference is still huge.

Later generations of wheat have been optimized from generation to generation to become excellent varieties, coupled with planting technology and fertilizer technology, especially the emergence of chemical fertilizers.

The fertilizer technology that Su Fan came up with was just a rough use of organic fertilizer.

Of course, chemical fertilizers are stronger, but in later generations, organic fertilizers have gradually begun to replace chemical fertilizers.

Although the effect of chemical fertilizers is good, the advantages and disadvantages are also obvious.

Chemical fertilizers are simple in composition and high in nutrient content; fast in fertilizer efficiency and strong in fertilization; generally do not contain organic matter, and have no effect of improving soil and fertilizing.

Long-term application will increase the content of heavy metals and toxic elements in the soil; reduce soil microbial activity, making it difficult to transform and degrade substances; nutrient imbalance, nitrate accumulation; acidification intensified, pH changes too much, etc.

Organic fertilizers are different. Compared with chemical fertilizers, organic fertilizers have complete nutrients; they can improve soil; improve product quality; utilization rate.

Organic fertilizers also have disadvantages. Although there are many types of ingredients, the content of each nutrient is relatively small, and the effect is relatively slow.

In this mythical world, can chemical fertilizers be researched?

Of course, it is possible. Although the original law of the later world and the mythical world are somewhat different, the microscopic particles are still similar.

With the power of Yuanshen, Su Fan can also observe those elements. Even now, Su Fan has a lot of fertilizers that he specially researched.

It's just that his fertilizer is produced by his mana, and it cannot be produced on a large scale.

In this era, if one wants to manufacture fertilizers on a large scale, one must either take out those production equipment, or, as he does now, use the ability of a monk to manufacture fertilizers.

The first method, the production equipment is not so easy, even if Su Fan can research them one by one, and then use the method of refining them to refine them, it may be very troublesome to implement.

The knowledge system requires countless people to study.

As for the second method, Su Fan felt that it was simpler, that is to use monks to make fertilizer.

Ordinary monks, even monks in the Qi refining period, can do it, as long as they show the refining method.

There are not many Daqin monks, but there must be many.

There must be hundreds of thousands. If they are used to refine chemical fertilizers, it will be relatively easy.

Of course, the implementation of chemical fertilizers can only depend on the ideas of the Daqin government. If they are willing to implement it, they can increase food production on a large scale.

With organic fertilizers, it's relatively easy.

For example, the fertilizer technology that Su Fan came up with before is actually the simplest kind of composting.

Su Fan naturally has more than this kind of compost. The one he promotes is the most suitable for large-scale promotion. The rest will definitely have better effects, but it will be more difficult to promote.

After all, most ordinary people cannot complete it.

But if the government does it, it will be much simpler.

Su Fan didn't hide these contents, he told Dayu all of them, especially the chemical fertilizers and organic fertilizers.

The effect of chemical fertilizers is stronger. Although there are disadvantages, it can greatly increase the grain production in the field in a short period of time.

"Is this thing easy to refine?"

Dayu couldn't help being excited, after Su Fan took out the fertilizer, Dayu immediately deduced it, and instantly he noticed the effect of this fertilizer, it was simply terrifying.

There is no field, but judging from his deduction, it is no different from field experiments, which can fully increase the harvest by half again.

According to today's Daqin, one stone is almost equivalent to sixty to seventy catties in later generations. The best field can have four stones, and if it is increased by half, it will be six stones per mu.

This number is really too high.

Dayu knew very well that to produce six shi of grain per mu was a great improvement for the human race.

This means that the human race can reproduce more population,

The current human race, not to mention other places, just the land of Kyushu, is still sparsely populated.

Too many places are not developed.

Many places are not impossible to develop. Most of the wilderness is uninhabited land, either wilderness or woodland.

These can be developed. The reason why the wilderness is not developed is that the yield of the wasteland is not high, but now with chemical fertilizers, even the inferior wilderness can yield three stones or even higher.

This allows for a larger population to be fed.

Many children bring blessings, but in the past, the Qianshou family could not support so many people, but now that the grain harvest is large, it is different. After a few years, there will be more and more food in the family, and more children can be born.

Twenty years later, the population will definitely explode.

Dayu was naturally able to deduce this scene. As far as the human race is concerned, the larger the population, the stronger the human race. This is a theorem, nothing more than a rebuttal theorem.

The reason why the Wu Clan combined with the Human Clan back then was that it was much easier for the Wu Clan to give birth to offspring than the Wu Clan. (end of this chapter)
