In addition to growing beans, the dry toilet that Li Yu had previously asked the designer to design can also be used.
These dry toilets not only prevent lizards from defecating on the church grounds and maintain a clean and hygienic environment, but also collect feces and urine for use in agricultural production.
In the continent of Bratis, farmers also fertilize the land.
The fertilizer they use is mainly livestock manure, in addition to lime and river mud, and farmers in coastal areas also sprinkle seaweed into their fields.
However, compared to the vast land, the fertilizer they can collect is somewhat limited.
Generally, these fertilizers are thrown into the farmland of winter crops, because these winter crops tend to grow better and can be sold at higher prices. As for the summer crops, they usually leave them alone.
Moreover, these farmers' methods of using fertilizers are also very primitive. They basically dump the collected livestock manure directly on the fields. In this way, the fertilizers often cannot be completely absorbed by the land, and it is also easy to attract underground pests.
As for human feces, it is generally regarded as filthy by the church and is not allowed to be applied to farmland on the grounds that it will contaminate crops.
Of course, Li Yu and Saturday behind him don't recognize this, so he must also use human feces.
Not only does the church belong to the land, Li Yu plans to personally talk to several other nearby villages and ask the villagers there to leave their excrement. At that time, he can send people to buy it regularly.
As long as you spend a little money, you should be able to get a lot of manure.
Li Yu did not plan to add the manure directly to the fields, but planned to use it as compost first.
The so-called composting is to mix the collected feces and urine with straw, weeds, fallen leaves, and pond mud, and then through the action of microorganisms, various complex organic nutrients are converted into soluble nutrients and humus, and fermented
High temperatures can also kill grass seeds, germs and pests.
Used as basal fertilizer, it can not only improve soil and soil utilization, but also significantly reduce soil-borne diseases.

There are hundreds of methods of composting. Composting in the north is usually done in a compost house. The compost pile is covered with rags or plastic sheets. If there is no compost house, it is not impossible to open it in the open air. However, exposure to the sun and rain will inevitably lead to a reduction in fertility.
In the south, pits are often dug for fertilization. Urine, green manure, weeds, stalks and pond mud are put into the pit and water is added for fermentation.
Li Yu was not sure which of the two composting methods was better, so he simply tried them both. Anyway, it was just a matter of building a shed and digging a pit.
All of the above are methods that can be used to increase production or improve efficiency immediately.
In addition, there is another thing that may not be effective in the short term, but if you persist in the long term, the benefits will be greater and greater, and it is also easy to be ignored, and that is - breeding.
Like animals, plants in nature are constantly evolving, although their evolution is often not very eye-catching.
However, the same plant often differs greatly after thousands of years.
For example, corn grown in the past 9,000 years was only one-tenth of its current size, with less than ten kernels on one corn. If you wanted to fill your stomach with this kind of corn, you would probably need thousands of kernels.
What's even more outrageous is the watermelon. Five thousand years ago, the watermelon was only 5mm long and had a shell as hard as a walnut. Under the shell, it was full of fat and starch. It was not easy to get the sweetness out of it.
Although most of the plants on the continent of Bratis are familiar to Li Yu, there are still many gaps between them and those in modern society.
Wheat, oats, rye, and carrots that the Arias family has been growing in large quantities are far different in yield and taste from what Li Yu often eats.
It's a pity that he couldn't bring seeds from another universe, otherwise if he just planted any kind, the native crops of this universe would be dead.
But Li Yu didn't have to wait for thousands of years like he did in the original universe.
Since the knowledge of genetics has been learned in junior high school biology classes, artificial intervention can be done through directional selection to greatly speed up the process.
The most famous example is hybrid rice.
The third-generation hybrid rice "Sanyou No. 1" developed by Academician Yuan Longping, known as the father of hybrid rice, has an average yield per mu of early rice and late rice combined that has even exceeded 1,500 kilograms, which is a biological miracle!
He used 7% of the world's arable land to feed 22% of the population, and it only took him a few decades to do this.
Unfortunately, there was no rice on the road in Bratis, and it was not easy to find male sterile lines. Li Yu could not copy the work directly.
But he has always attached great importance to breeding.
In fact, Li Yu had already started to do this not long after he arrived in Luye. He entrusted Miss Rabbit to help him find four boys and girls.
Among the filtering criteria given at that time was that it was best for the family to engage in farming.
Later, Li Yu also taught them Arabic numerals, just to facilitate their statistical research in the future.
Not long ago, Li Yu had given them the first task, asking them to select those with the highest yield and best quality in the field during harvest, or those that were resistant to pests and could survive in harsh environments.
Specialty crops grown under.
Collect their seeds and record their characteristics.
Li Yu will specially open several experimental fields on the church's land to plant these special crops, continue to select plants with other outstanding characteristics from their descendants, continue to cultivate them, and promote them at the appropriate time.
This process is a bit like brushing entries. It takes patience and a little luck to brush up red entries.
However, once you find good terms, such as cold tolerance, drought tolerance, and salt-alkali tolerance, and successfully retain them, you can definitely make a lot of money.
…………
The agricultural revolution initiated by Li Yu is bound to have a profound impact on the civilization process on the Bratis continent.
However, like all great changes, not many people paid attention at the beginning.
People's eyes still stay on those big shots, uu read www.uukanshu.com Stay
In their decadent or boring daily life, the nobles' love, hate, and every move can cause a lot of topics.
And to say who is the most popular figure in the entire Western Region recently, it has to be Yin Leiya, the new head of the Arias family.
The Arias family, which is located in a remote rural area, has always kept a low profile. It has been a long time since there has been any amazing person or any great achievements worth writing about.
However, it has been unusual in recent times. First, the election of the head of the family was brought to the attention of Marquis Cullen, and then he took the initiative to make the election process public. In addition, there were twists and turns, and mysterious foreigners appeared on the stage to perform miracles, which can be said to have earned a lot of attention.
It is said that the two candidates had a fight after returning to the territory. Seeing that the victory was decided, everyone thought that the show was about to end. No one expected that Yin Leiya, who had just taken power not long ago, would have another climax.
The head of the Arias family asked Marquis Cullen and other nobles in the West for help overnight, claiming that he had suffered a large-scale attack by the Lizardmen, and begged them to send troops to help rescue the innocent citizens in the territory who were besieged in the Teacup Castle.
of a tribe of people.
But before each family could figure out the specific situation, just one day later, Yin Leya withdrew her request for help, saying that the crisis had been resolved.
When receiving the letter, many heads of the family turned into question marks. They couldn't figure out what the person who wrote the letter wanted to do. But after half a month passed, the new head of the Arias family seemed to remember,
I haven't held a party since inheriting the territory.
So he wrote to the nobles in the Western Region and invited them to visit his territory.
