323 Biogas and circular agriculture

The significance of joining this small customs union for Lawrence is not only to bring his territory into this trading circle, but more importantly, it means that he can integrate into the surrounding environment. After all, people are social animals, and so are countries.

.It is much better to communicate with the outside world than to be closed to the outside world.

In addition to these normal harvests, the participating lords agreed to purchase the grain sold by New Shaoer at a premium of 20% based on the average grain export price of the top 15 trading ports along the Star Sea coast in the month. And

All are picked up on New Sol Island.

In other words, as long as Lawrence grows the grain, someone will come to buy it. There is no need to worry about the sales of the products. This is very good news for Lawrence, who has just established a foothold in this area.

After completing the mission, the ship Lawrence took returned directly to his own territory. In just half a month, New Saul Island has undergone tremendous changes. For example, the original temporary trestle has been replaced by a semi-permanent one.

The wooden pier was replaced. Not far away, a group of people were preparing to use cement and stones to build a real permanent pier.

In addition to the pier, Lawrence also saw five or six huge windmills appearing on the coastline. Presumably this was because the steam engines that came ashore temporarily needed to be used in more important places, so the craftsmen who came to the island with the ship simply used the seaside

The nearly constant sea breeze built several windmills to supplement the steam engines.

"Lord August, you are finally back." As soon as he got off the boat, Lawrence was stopped by several priests wearing brown priest robes. "You told us before that we were going to repair the biogas digester and we have already repaired it. Next we will

what to do?"

This group of agricultural priests was not called here by Lawrence just because of favors. If they were just favors, it would be great to call one or two technicians. And the reason why they sent a small team is because Lawrence was there.

In the letter, he wrote a conjecture about circular agriculture and said that he would use his own territory to test this conjecture.

As the daughter of the Mother Goddess of the Earth and the Father of Nature, the Goddess of Agriculture has always been in a state of tangle and contradiction. On the one hand, the inheritance she received from her parents tells her to protect the natural world, but on the other hand, her priesthood requires

She stands on the side of intelligent creatures and develops agriculture as much as possible to produce more agricultural products.

But in this way, the development of agriculture will inevitably require the destruction of the natural world. Especially after the industrial revolution, the destruction of the natural world by intelligent creatures, especially humans and dwarves, has become very serious, and a large part of it is attributed to agriculture.

Development. For example, large-scale land reclamation will seriously damage natural vegetation, and the misuse of chemical fertilizers can easily damage the soil.

The circular agriculture mentioned in Lawrence's letter to the church gave the goddess of agriculture hope, a hope for human development and the natural world to coexist as harmoniously as possible. This is why she issued an oracle and sent such a message from the agricultural church headquarters in the New World.

The reason why a capable team that has reached Silver level came to this island.

However, because Lawrence learned all this knowledge from the Internet, he only had a rough framework. In addition, considering that even if different worlds look similar, they are likely to be different in some microscopic aspects. So he simply excepted the knowledge

The remaining details outside of the framework are all announced after completing the previous step and what to do next. This allows for timely adjustment of errors and avoids problems due to dogmatism.

But as a result, the members of the Agricultural Church who had been working overtime with great enthusiasm suddenly found that they no longer knew what to do after they efficiently completed the construction of the biogas digester arranged before Lawrence left. So they waited in boredom for two days.

Time, that's why they were so excited when they saw Lawrence back.

Building a biogas digester is a very important thing for Lawrence. After all, as an area dominated by agriculture, sufficient fertilizer is essential. In addition, the unified fermentation of manure and various perishable organic matter is very important for the environment.

For Lawrence in the tropics, it is an effective means to block infectious diseases.

More importantly, the hot and humid climate in this area all year round is actually very suitable for biogas fermentation. The biogas digester can be used all year round instead of only a few months like in Lawrence's hometown in the north. However, although he is very fond of his hometown in his previous life,

He was dissatisfied with the biogas digester that could only be used for a few months, but if it hadn't been for that incident, Lawrence would not have had this information about the construction of the biogas digester in his mind.

While thinking about these things, Lawrence and the clergymen of the Agricultural Church came to a circular building made of cement. In a small room next to the building, several large pots filled with water were placed.

The biogas stove is already boiling, and two farm workers are working together to pour the boiled water into the kettles.

"After the first batch of feeding, all the biogas digesters have been running smoothly." The leading priest of the Agricultural Church said to Lawrence with a satisfied smile. "At the beginning, there were one or two biogas digesters that were not operating properly.

Normal, but after your life-constructing companion checked, they all returned to normal."

"Because I have told my companion about this before, so she is more aware of these details." Lawrence explained after listening to the priest's words. But in fact, he was still confused in his heart, because he did not remember Na

Ra had shared this type of knowledge with himself.

Of course, everyone has their own secret. Although the birth of Nora has a lot to do with Lawrence, it is not inconsistent with having his own secret. Lawrence respects the privacy of the little doll as an independent individual and feels that

The reason why she didn't say it must have her own reasons. She didn't intend to explore it further.

These fuels are actually very important to the island, because Lawrence discovered that most people in this era are drinking raw water not because they want to drink raw water, but because boiling water requires enough raw materials, but ordinary people usually don’t have much fuel.

Just being able to cook the rice is already pretty good.

After the Industrial Revolution, people in cities were finally able to obtain cheap enough coal and even gas as fuel. But in the vast countryside, firewood obtained from woodcutting was still their only fuel.

Therefore, an important reason why Lawrence established a collective canteen in the past was to reduce fuel consumption, and then squeeze out precious firewood for boiling water. By boiling water, we provided clean water sources to the people to avoid the outbreak of tropical diseases. But now it can be done 24 hours a day

The biogas digester that provides fuel every hour further reduces fuel consumption.

"In addition to producing gas that can be burned, the things in the biogas pool will heat up during fermentation, destroying the pathogenic bacteria that may be carried inside. At the same time, the final fermented biogas slurry and biogas residue can be improved

The soil can increase crop yields. Adding it to feed can also promote the growth of livestock." After walking out of the hot water room, Lawrence said to these agricultural priests.

There were also early chemical fertilizers in this era, such as mineral fertilizers such as superphosphate. However, due to the limitations of the chemical industry in this era, there were often problems with the free acid content in the fertilizer being too high and being mixed with a large number of impurities. This led to

Severe soil pollution occurs and soil compaction eventually affects the growth of crops.

For the Agricultural Church, fertilizers that can greatly increase food production are naturally very good, but if this increase in crop production is obtained by damaging the soil, it would be very, very bad. This is the solution they received from Lawrence.

The reason why I came here in such a hurry after the plan.

"This biogas digester is an important part of what I call circular agriculture. In the process of creating circular agriculture, we must promote the multi-layered and efficient flow of various agricultural resources in the farming system to achieve

The purpose is to save energy, reduce emissions and increase income, and promote the sustainable development of modern agriculture and rural areas."

Since calling others all the way from the New World to do the work for so long has helped so much, then Lawrence should also come up with some dry goods and give them to these agricultural priests. After all, everything is about one thing.

Equivalent exchange, just giving others a pie will definitely not work.
