"I'm very professional: it's better to use urine directly, plant ash for potassium fertilizer, and ashes for phosphate fertilizer, so that the material is easy to find, and the effect should be okay." 》

"Time for you to sing a song: plant ash is not high in potassium, bones are not high in phosphorus, and excessive use of land will turn sour and burn roots." 》

The people of various dynasties saw the comments on the canopy, looked at the rear view on the canopy, and let them directly use things such as urine or ashes and bones, and their eyes lit up.

These things are easier to find and use than the soil and fertilizer on the canopy.

Their bright eyes dimmed again when they saw the second comment, and they didn't expect that these things didn't work very well, and that using too much would burn the rhizomes of the plants.

At the same time, they are also rejoicing, glad that it is freezing now, and they did not immediately go to the experiment as stated in Tianmu, directly using urine, plant ashes, ashes and other things.

At the same time, they also began to worry, is there such a side effect of the soil fertilizer on the canopy?

And those people in the warm weather in the south, they are full of regret after seeing the comments on the canopy.

Did the comments on the canopy do they really do it in order to experiment? But I did exactly what the sky said.

Some people even use a lot of what is said on the screen in order to get more production.

Now they regret it, regretting why they can't resist the impulse in their hearts, the temptation of high grain yields?

But now it is useless to regret everything, they can only find a way to make amends.

They found the river and began pouring large amounts of water into their fields, hoping to dilute them and leave their crops unharmed.

The emperors of various dynasties looked at the comments on the canopy, and they were glad that they didn't easily believe what the canopy said.

Otherwise, if it is implemented on a large scale, it would be good not to say that grain production will be increased and not reduced.

Still, he ordered the officials to continue experimenting, after all, they could not escape the temptation of normal food.

And they felt that since the people of later generations on the canopy had spoken out about his shortcomings, there must be a solution.

What just makes them sigh is that the people of later generations have not said how to solve it, they can only use these fertilizers carefully.

Wei.

Jia Siqian looked at the comments on the canopy, and he fell into deep thought.

As a professional in agriculture, he wrote the "Book of Qi Min", a huge work to promote agriculture, and he has his own judgment.

In his opinion, if the soil fertilizer in Skylight City really worked, it would benefit all the people.

And if the direct use of plant ash and bones can also increase the yield of the dealer, it can also be used.

As for the roots of decaying plants, in Jia Sixian's view, these two substances can be diluted completely to achieve the effect of increasing grain production without harming the roots.

Then his doctrine was popularized, and countless people pondered it and felt that it was very reasonable, and they decided to experiment it after the beginning of spring next year.

They don't want their food to be as productive as the generations to come, but they want it to be a little bit more so that they can have a full meal.

Song dynasty.

Shen Kuo looked at the comments on the canopy, he picked up the pen and paper in his hand, and recorded these contents in his "Dream Creek Pen Talk".

Although these things have been broadcast on the canopy and are known to the people of the world, with the passage of time, some people will forget, and even some people will question it, and he wrote in his "Dream Creek Writings" in the hope that he can prove the effects and side effects of these things.

At the same time, he began to pay attention to what potassium and phosphorus are, because plant ash and bones contain a small amount of components, which cannot make a large amount of grain high-yield, if there is a way to let the land have a large number of these two components, will the yield be like that of later generations?

Ming dynasty.

Xu Guangqi saw the comments on the canopy, and he fell into endless silence.

At this time, Daming was a time of continuous disasters, countless people were waiting for a mouthful of food to save their lives, if the method on the canopy was really useful, he believed that His Majesty would definitely implement it today.

Even if there are consequences, he will be asked to find a solution.

After all, in this era, if you can have one more bite of food, you can save one more life.

Moreover, His Majesty is a diligent lord today, hoping that he can turn the tide and realize the prosperity of the Ming Dynasty.

Moreover, in Xu Guangqi's view, His Majesty was born in the wrong era, otherwise it would definitely be a generation of democracy

It's a pity, it's a pity!

"The low-key librarian: Some people say grass ash, compost or something. How much urine do you think you need, how much plant ash you need to burn, where are the ashes? Without modern chemical industry, the yield per mu is less than 1/3 of the present, and the yield per mu in ancient times was 200-300 catties. There is simply no way to feed so many people. 》

"The Son Shall Not Speak Nonsense: Why is it called Tufa? This is because these materials do not have the conditions to be supplied in large quantities on a continuous basis. In this way, fertilizer will not be able to increase the yield of large areas of arable land. 》

"The Tide of Industry: That's Why It's Called Soil Fertilizer, Soil Method = Preparation Method in the Non-Industrial Era; Crossing = the era of deindustrialization. Wouldn't it be good for you to go to the farming civilization and use the relatively leading soil methods in the era of farming civilization? I still want to go to the sky in one step. 》

The dynasties saw the comments on the canopy, and they fell silent.

They also knew that it was impossible to use all the land with the method described in the canopy, but they still had expectations, at least the methods commented on in the canopy.

However, they wanted to know the results of the imperial court's experiments, after all, if their fields were easily used with soil and fertilizer, the consequences were not something they could bear.

However, in order to get the results of the soil fertilizer as soon as possible, they still decided to open up a little test field in their own field, and wait for the next spring to experiment there.

At the same time, they are also very curious, what is the chemical industry in the afterlife on the canopy to the present? It is possible to obtain a large amount of fertilizer that can make it a high yield.

Not only are they curious, but the emperors of various dynasties are also curious, especially Zhu Yuanzhang, after all, as said on the canopy, the Ming Dynasty almost achieved capitalism and industrialized the entire society.

It's just that what makes people sigh is that the Ming Dynasty was finally annihilated by Najiannu, and the civilization that the Han people worked hard to create was trampled and buried in the pile of old paper of history.

And now they have comments from the sky, they definitely don't want their dynasty to go the same way, they also want their country to become stronger and stronger, and their people to become richer and richer.

And their eyes are not only on the current territory, but also on the vast overseas world.

They want to make the whole country richer, have more financial resources to occupy more land, so that future generations can live a richer life!

It will not be in a certain dynasty and be invaded into the capital by the Eight-Nation Alliance, which almost destroyed the whole of China!
