Chapter 719 Jin Ke La, Jin Ke La, let’s test Jin Ke La
In fact, it’s not that Gretel doesn’t know the answer.
He wanted to report the results directly. Nitrogen, phosphorus and potassium. You can just test these three, but there is no way to cheat.
Besides, what if the plants in this world need other elements to grow?
He didn't give an answer, so the alchemists had no choice but to roll up their sleeves and go through all the available testing methods.
Such as [detecting toxicity], such as [identification technique], such as the simplified version of Gretel's spread [blood potassium test], etc...
"[Detect Poison]!"
"There is phosphorus in the soil!" cried an alchemist:
"There is actually phosphorus! Although the amount is not large, I only knew that phosphorus can be found in cemeteries and ores. Is it also found in soil?"
"Is there really phosphorus in the soil?" Seven or eight heads came over, and a row of [Detecting Toxicity] swatted it down. Then, discussions started one after another:
"There's really phosphorus!"
"Then why aren't there any will-o'-the-wisps floating inside?"
"Perhaps the phosphorus content is relatively low?... Go back to the burial ground in Black Crow Swamp and test it again for comparison. Who will follow me?"
"Well, but I don't know the magicians in Black Crow Swamp, and I can't enter their territory... Do you know anyone? Can you introduce them?"
"Hey, can you ask the Lord of Plague to introduce you? We are all working for him."
"Snapped!"
A slap hit the speaker's forehead.
Gretel:→_→
He pretended not to hear anything and drifted away silently. When he walked to another stall, he saw several alchemists gathered in a cluster, pouring magic into the solution:
"[Identify Bloodline·Change]! Hey, this spell is so convenient for measuring potassium content! We used to use the titration method, but we couldn't measure it!"
Humph, [Distinguish Bloodline·Change], or in other words, the flame ion method... or is it called atomic spectroscopy? It is used to measure metal ion content, and the effect is still great!
Others put out flasks and beakers and began to do titrations;
Some people measure pH;
Some people crackle, shoot various spells, and adjust various magic arrays;
Some people hold a big notebook and compare it bit by bit with what is displayed on the instrument...
Hey, this looks like a titration method. Could it be a spectrophotometer colorimetry method? What is this method?
No matter, I am the conductor of the experiment anyway, and I don’t need to do the work with my hands. I just need to look at the results they measured and see that they are about the same...
"Little Gretel, which part are you responsible for?"
Seeing Gretel clasping his hands in front of his belly, dangling around, doing nothing, Elder Wood couldn't help but smile and asked. Gretel shrugged:
"I, I will wait for them to produce the results and then summarize them..."
"But I didn't see you working either."
A magician next to him was so busy that he was sweating profusely. He wiped his forehead and wiped his face with black and gray streaks.
Although high-level mages do not have to work with their own hands, and although leaders can hang around and supervise others as long as they design experiments, he seems too relaxed!
He didn't even take out his notebook!
The summary results will be calculated later, what should he use to calculate them!
Grete silently took out the mobile version of the tower spirit. In an instant, all the casters' eyes were straightened.
...big dog owner!
After taking the soil samples, the magicians all evacuated. The priests of the God of Nature re-entered and started working:
The collective use of divine magic quickly caused the grains in this field to take root, germinate, emerge, and tiller. Then, the growth process was like a fast lens, slowing down slightly...
"Stop, stop, stop! Sampling team, come in!"
There was a flurry of excitement. The priests stood on tiptoes and evacuated one by one. There was a young priest who was not familiar with Gretel. He was stopped in the middle of releasing the magic, and his breath choked on his chest. He coughed for a long time, with tears in his eyes.
complain:
"What are you doing...you have to stop in the middle of casting...rely on these magicians to really measure how much fertilizer should be used..."
"Shh!" the priest closest to him shouted in a low voice:
"Don't say this in front of others! That Nordmark mage, oh, he is actually the priest of our order. Do you know how many things he invented! Penicillin, cowpox, including the compost we are using now, are all from him
Get up!"
The young pastor stopped talking. The older man whispered:
"Besides, priests have priests' methods, and magicians have magicians' methods. Maybe they can do it?"
Then, the magical team came in for the second time to promote the growth of the seedlings. After jointing, booting, and taking another soil sample; after heading, flowering, filling, and maturing, the last soil sample was taken. The magicians in charge of the test were busy again.
Towards the sky.
Finally, several sets of data were gradually collected into Grete's hands. He just clasped his hands in front of him, walked in groups, and checked one by one:
"There's something wrong with this! Do it again! You are a group, and your data is ten times that of the others. There must be something wrong!"
"There's something wrong with this! Why is the iron content higher than potassium? Do you think this is iron ore? Redo it!"
"This..."
Picking and picking, throwing back one piece at a time. The magician who was beaten back to do it over by him dared to be angry but dared not speak, but he couldn't refute, so he had to work honestly. Only Elder Wood could make two jokes:
"Grete, you really look like an overseer... If your hands are not held in front of you, but behind your back, it would be more like..."
Gretel:……
There is no way, surgeons are used to it, and this is the result.
These are still unwashed hands. If the hands have been washed, the posture will be even more awkward. They are either held on the chest, or held flat on the chest. The upper part does not reach the shoulders and the lower part does not reach the waist.
You can spread it a little to both sides, but touching the back is definitely not allowed!
He corrected the data, and then asked the mobile tower spirit to scan, input, and make charts. Tables, line charts, and a large sheet were typed out. Gretel immediately wanted to cover his eyes:
"Hmm... I look so tired..."
The boss has a table with dozens of elements, such as copper, iron, calcium, and magnesium. Gretel pressed his hand on the tower spirit and whispered:
"Come on, take the first result and the last result and rearrange the table according to the difference from largest to smallest!"
With a swipe sound, the form was drawn up again. Grete read it one by one from top to bottom, and was quite satisfied:
Yes, yes, nitrogen, phosphorus and potassium account for the majority. As for other trace elements, it shouldn’t be a big problem, even if it’s a little bit, it won’t affect the harvest.
He looked around and clapped his hands:
"Repeat this experiment 10 times and take the average. Then, um, measure the nitrogen, phosphorus and potassium content of the manure, and also measure the content of the river mud..."
"No"
In the group of mages, wailing could be heard everywhere.
