The Rise of the European Emperor

? In addition to providing volcanic ash as fertilizer, Marin also provided "high-tech" ploughs such as curved ploughs to replace the Saxon heavy and light plows used in these old-fashioned aristocratic homes to further improve farming efficiency.

Originally, Marin also planned to provide them with the "new agricultural technology" of the cow nose ring. In this way, the use of cattle farming can also save costs. But then I thought about it again - it seems that horse farming is faster and more efficient, it is better to continue to maintain horse farming.

Europe is different from China, where there are many people in China, and there is no shortage of labor. Natural cattle farming is more cost-effective. Europe lacks people, and America lacks people even more, so it is better to promote faster horse farming.

In fact, Marin has been hesitant to promote manure. However, once the promotion of manure was known to outsiders, food production throughout Europe would soar. At that time, the level of agricultural production in Europe will be able to catch up with China. And Marin, it is difficult to rely on selling food to make a fortune.

So, Marin didn't let anyone know the secret of manure anyway. However, it may take several months to process the manure so that it loses its odor. Otherwise, if there is a trace of odor left, it will be recognized as feces.

Also, the appearance of feces, even if the smell is lost, is easy to identify. After all, poop is not an uncommon thing. Even if it is air-dried and the taste is gone, you can still see the original appearance vaguely.

However, Marin now has a special person to handle the manure, then mix it with phosphate fertilizer and potassium salt, and then send a special person to fertilize it, which consumes huge human resources and is very uneconomical.

So, Marin has been thinking about it now - how to dispose of the feces so that they can't be seen as feces...

Coincidentally, Marin thought a lot about the redistribution of interests in Bremen Province this time...

However, he doesn't seem to be able to deal with the stench of the feces. If you add too many other things, it can cover the taste. However, it also reduces fertility...

How to do it? So Marin went to the Elbe River to fish and relax...

Marin randomly found a fishing rod from the house of the noble who had been raided. Accompanied by several guards, he went fishing by the Elbe River.

As for bait? This is easy, Marin beckoned, and a few hard-working guards started digging earthworms by the Elbe with their sabres...

When a pile of earthworms was brought to Marin's eyes, Marin looked at the disgusting-looking earthworms wriggling all over the floor, and suddenly his inspiration was triggered...

...

What was Marin's inspiration? He remembered a later news report about raising earthworms with cow dung...

This report,

Hidden deep in Marin's memory. After all, it wasn't important information, and Marin never thought of it. But this time, when he saw a pile of earthworms dug up by the guards, he suddenly remembered this news.

"Yeah! I can dispose of manure with earthworms!"

Earthworms are experts at eating dung, and like maggots and dung beetles, they love to eat dung. However, when maggots eat dung, they will turn into flies and harm the world. The dung beetle likes to roll the feces into balls and hide them in the soil...

Only earthworms like to loosen the soil. Moreover, after eating feces, the vermicompost pulled out is called "the king of organic fertilizers".

In the report in Marin's deep memory, it was mentioned that a farmer collected cow dung from a nearby dairy farm to raise earthworms. Then, vermicompost is obtained, which is then used as organic fertilizer to grow organic vegetables...

Organic vegetables cannot use chemical fertilizers, but they do not grow well without fertilizers. And using manure as fertilizer is too smelly. Moreover, the use of animal manure as fertilizer also provokes flies.

And using vermicompost as fertilizer, not only vegetables grow well, but also absorb quickly...

In addition, farmers who use cow dung to breed earthworms also use earthworms to feed eels. Eel likes to eat earthworms the most, and it grows well after eating earthworms. Moreover, the price of eel is high, dozens of yuan per pound...

Relying on cow dung to raise earthworms, earthworm dung to grow organic vegetables, and the ecological agriculture technology of earthworms to breed eels, the farmer earns millions a year and crushes many high-tech talents...

However, that report also said that for raising earthworms, it is best to use the dung of herbivores such as cow dung and sheep dung. Because it seems that the pH value and ammonia content in the feces of carnivores and omnivores exceed the standard, making earthworms unbearable. Only cow dung and sheep dung are the dung of herbivores, which have a lot of cellulose and not so smelly, so earthworms can adapt more, and they can be eaten immediately and transformed into earthworm dung that does not smell at all...

If it is human excrement, it may need to be fermented, or even composted with biogas, before it can be used as feed for earthworms.

This is also normal, because human feces, as agricultural fertilizers, cannot be fertilized directly into the fields. Previously, compost fermentation was required before being applied to fields as fertilizer. If you do not deal with it, fertilizing directly on the seedlings will easily burn the seedlings.

Although he didn't know the principle of burning seedlings, Marin knew that feces that could burn seedlings could not be used to breed earthworms. But if it is processed, although it is not as popular as earthworms as cow dung, it can also be used to breed earthworms...

...

Of course, Marin doesn't think vermicompost is much more fertile than straight dung. In fact, there are limited differences in fertility, except that vermicompost is more easily absorbed by crops.

What Marin values ​​most is that the vermicompost has no odor. Also, it looks like dirt. Although it looks like a grain, the vermicompost is odorless. It looks like a grain of soil, and it is difficult for half of the people to guess the relationship between it and discrimination, which is more conducive to Marin to hide the secret of manure...

In addition, cultivated earthworms are themselves a very good feed. For example, it is used to breed high-value eels...

"Wait...it seems... the eel is a species from East Asia..." Marin suddenly remembered that it seems that the yellow eel (long fish) is a product of East Asia...

Although it is said that eel is a famous food in later generations. However, in this era, there are no eels in Europe. Even if Marin introduced the eel from the Ming Dynasty, Europeans may not dare to eat the snake-like shape of the eel. Maybe, if you use earthworms to breed eels, there is a possibility that the eels cannot be sold...

However, it seems that earthworms are a very good food whether they are good for eels or chickens, ducks and geese. In a previous life, when Marin was a child in his hometown in the countryside, he often saw scenes of old hens turning the soil to find earthworms to eat. Also, ducks seem to like eating earthworms. Marin has seen the funny scene of two ducks dueling each other in order to compete for an earthworm. Later, the two ducks each grabbed one end of the earthworm, sucked and swallowed hard, and then the two ducks "kissed"...

...

It just so happened that Marin had developed the kang room incubation technology before, which made Beihai Kingdom have a lot of chicks, goslings and ducks. But the problem is - farmers lack feed...

These days, when European grains are so expensive, it is absolutely extravagant to feed chickens. Therefore, after Marin popularized the hatching technology of kang room, the most hatched ones were not chickens, but geese...

Why? Because geese eat grass, unlike chickens, they need to find live animals to eat or eat grains.

Therefore, in ancient times, Europeans actually preferred to keep geese. Because the cost of raising geese is low... After all, geese eat grass...

For this reason, before dying, the little girl who sold matches imagined a fragrant roast goose instead of roast chicken. In ancient times of Europe, which encouraged expensive prices, chickens were more expensive, and geese were more popular...

It's just that ducks and geese don't seem to like hatching eggs. Therefore, even if ducks and geese lay eggs, they are not as patient as hens to hatch. So, ducklings and goslings are rare. But as long as the goose is hatched, it is much easier than raising chickens... But compared to the tender meat, chicken is better...

Right now, after Beihaiguo had hatched the kang room, it had gotten a lot of goose eggs and let the manor be stocked. Because geese eat grass, the cost of feeding is low.

...

But now, if Marin promotes the technology of raising earthworms with feces, he can get a lot of earthworms. Then, raising chickens is very promising. Chickens that eat earthworms not only grow faster. Moreover, it is said that the order rate of hens can also increase...

In other words, as long as the feces are used to raise earthworms, not only can the source of the feces be concealed, but also a large number of chickens can be raised. In the future, I am afraid that ordinary people in Beihai will be able to afford chicken and eggs. It will definitely benefit the people!

So, Marin immediately ordered the establishment of earthworm farms in all manure processing plants across the country. Let the earthworms process the fermented feces into earth-like vermicompost that others can't recognize. In this way, when the nitrogen fertilizer is taken out, others can't guess the source...

At the same time, a large-scale chicken farm was set up next to the earthworm farm. Whether broilers or laying hens are on the horse, in this way, the citizens of Beihai will not be short of chicken and eggs in the future...

"I'm such a genius! Not only did I solve the problem of keeping the manure secret, but I also developed a very promising chicken industry!" Marin laughed smugly...
