In addition to providing volcanic ash as fertilizer, Marin also provides a "high-tech" plow, a curved plow, replacing the Saxon heavy plow and light plow used by these old noble families to further improve the efficiency of plowing fields.
Originally, Malin also planned to provide them with "new agricultural technology" such as the bull nose ring. In this way, using cattle plowing can also save costs. But later, I thought that it seems that horse plowing is faster and more efficient, so it is better to continue to maintain horse plowing.
Europe is different from China. There are many people in China and there is no shortage of labor, so naturally ox plowing is more cost-effective. Europe lacks people and America lacks people, so it is better to promote faster horse plowing.
In fact, Marin has been hesitating about how to promote manure. However, once the promotion of manure is known to outsiders, the grain output in the whole of Europe will rise sharply. By then, Europe's agricultural production level will be able to catch up with China. And Marin will find it difficult to make a fortune by selling grain.
Therefore, Marin did not make any noise to let others know the secret of manure. However, it would probably take several months to process the manure and make it lose the smell of manure. Otherwise, a trace of odor would be recognized by people.
Also, even if the feces lose their odor, they are easily recognized. After all, feces are not an uncommon thing. Even if they are air-dried and smelled, they can still vaguely see their original appearance.
Marin now has a special person to deal with the feces, then stir with phosphorus fertilizer and potassium salt, and then send a special person to fertilize. The human resources consumed are huge and very uneconomical.
So, Marin has been thinking about how to deal with feces so that it is shit...
Just so happened that this time, Marin thought a lot about redistribution of interests in Bremen...
However, he seemed to be unable to solve the odor of the feces. If he added too much other things, it would cover up the smell. However, it also reduced his fertility...
What should I do? Marin ran to the Elbe River bored and went fishing and relaxing...
Marin casually found a fishing rod that was found from the family of the scouted nobleman, and accompanied by several guards, he went to the Elbe River to fish.
As for the bait? This is easy, Marin waved, and several hard-working guards began to dig earthworms by the Elbe River with their swords...
When a pile of earthworms were sent to Marin's eyes, Marin looked at the squirming and looked disgusting earthworms, and suddenly the inspiration was triggered...
...
What inspiration did Marin trigger? He remembered a news report in later generations about raising earthworms with cow dung...
This report was hidden deep in Marin's memory. After all, this was not important information, and Marin never expected it. But this time when he was fishing, he immediately remembered the news.
"Yes! I can use earthworms to treat the feces!"
Earthworms are masters of feces. Like maggots and dung beetles, they like to eat feces. However, maggots will turn into flies and harm the world. The dung beetles like to rub feces into balls and hide them in the soil...
Only earthworms not only like to loosen the soil. Moreover, the earthworm manure that is pulled out after eating feces is called the "king of organic fertilizer".
In the report deep in Marin's memory, it was mentioned that a farmer collected cow manure from a nearby dairy farm and used it to raise earthworms. Then, he obtained earthworm manure, and then used it as organic fertilizer to grow organic vegetables...
Organic vegetables cannot be made of fertilizer, but they cannot grow well without fertilizer. Using feces as fertilizer will be too odor. Moreover, using animal feces as fertilizer will also cause flies.
Using vermicompost as fertilizer not only makes vegetables grow well, but also absorb quickly...
In addition, farmers who use cow dung to breed earthworms also feed eels with earthworms. Eels like to eat earthworms the most. After eating earthworms, they grow well. Moreover, the price of eels is high, dozens of yuan per pound...
Relying on cow manure to raise earthworms, earthworm manure to grow organic vegetables, and the ecological agricultural technology of earthworm breeding eels, the farmer earned millions a year and crushed many high-tech talents...
However, that report also said that it is best to use herbivorous feces such as cow manure and sheep manure. Because it seems that the pH value and ammonia content in the feces of carnivorous animals exceed the standard, which makes the earthworms unable to bear it. Only cow manure and sheep manure are the feces of herbivorous animals, with a lot of cellulose in it and the taste is not so smelly. Only earthworms can adapt more and can eat it immediately and turn it into earthworm manure that is not smelly at all...
If it is human feces, it may need to be fermented or even fermented with biogas before it can be used as feed for earthworms.
This is also normal, because human feces, as agricultural fertilizers, cannot be directly fertilized into the fields. Previously, compost and fermentation were needed before they could be applied to the fields as fertilizer. If they were not treated, fertilized directly on the seedlings, it would be easy to burn the seedlings.
Although I don’t know the principle of burning seedlings, Marin knew that feces that can burn seedlings cannot be used to breed earthworms. But if it is processed, although it is not as popular as cow manure and earthworms, it can also be used to breed earthworms...
...
Of course, Marin does not think that vermicompost is much more fertile than direct manure. In fact, the difference in fertility is limited, but vermicompost is easier to be absorbed by crops.
What Marin values ​​most is that the earthworm manure has no smell. Moreover, it looks like soil. Although it looks like grains, the earthworm manure has no smell. It looks like soil particles, and it is difficult for ordinary people to guess its relationship with feces, which is more conducive to Marin hiding the secrets of manure...
In addition, the earthworms raised are also a very excellent feed themselves. For example, they are used to breed high-value eels...
"Wait... It seems... eels are species in East Asia..." Marin suddenly remembered that it seemed that eels (long fish) are East Asia products...
Although eels are a famous delicacy in later generations, there were no eels in Europe in this era. Even if Marin introduced eels from the Ming Dynasty, Europeans might not dare to eat them with snake-like appearance. Perhaps, if eels are raised with earthworms, there is a possibility that eels cannot be sold...
However, it seems that earthworms are a very good delicacy for eels, chickens, ducks and geese. In the last life, when Malin was a child, he often saw old hens rummaging over soil and looking for earthworms to eat. Moreover, ducks also seem to like to eat earthworms. Malin saw the funny scenes of two ducks fighting each other for a fight for one earthworm. Later, the two ducks each grabbed one end of the earthworm and sucked it hard. Later, the two ducks "kissed" the mouth...
...
Just so happened that Malin had developed the kang house hatching technology before, which made many chicks, gooses and ducks in Beihai Country. But the problem is that farmers lack feed...
These days, European grains are so expensive, and it is definitely a super luxury to feed chickens. Therefore, after Marin promoted the kang house hatching technology, the one that hatched the most was not chickens, but geese...
Why? Because geese eat grass, unlike chickens who need to find living food or eat grains.
Therefore, in ancient times, Europeans actually prefer raising geese. Because raising geese is low... After all, geese eat grass...
Therefore, before dying, the little match girl fantasized about fragrant roasted gooses instead of roasted chickens. In ancient Europe, when grains were expensive, chickens were more expensive and geese were more popular...
However, ducks and geese do not seem to like hatching eggs. Therefore, even if ducks and geese lay eggs, they are not as patient as hens. Therefore, ducks and geese are rare. But as long as they hatch, it is much easier than raising chickens... But compared to tender meat, chicken is better than chicken...
At present, after the Beihai Kingdom has set up a kang house to incubate, it has made a lot of goose eggs to let the manor stock. Because geese eat herbs and raise costs are low.
...
But now, if Malin promotes the feces and earthworm raising technology, he can obtain a large number of earthworms. Then, there is a lot of opportunity to raise chickens. The chicken that eats earthworms will not only grow fast, but also, it is said that the hen order rate can also increase...
In other words, as long as you get the feces and raise earthworms, you can not only cover the source of the feces, but also raise a large number of chickens. In the future, I am afraid that ordinary people in Beihai will be able to afford chicken and eggs, which will definitely benefit the people!
So, Malin immediately ordered that the earthworm farm be set up in all manure processing sites across the country. The earthworms could process the fermented manure into earthworm manure similar to soil that others could not recognize. In this way, if the nitrogen fertilizer was taken out, no one could guess the source...
At the same time, a large-scale chicken farm was set up next to the earthworm farm. Whether it was broiler or laying hens, the people of Beihai Kingdom would not be short of chicken and eggs in the future...
