Chapter 725 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 phosphorus! Although the amount is not large - but, 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 slapped down a row of [Detecting Toxicity]. 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 introduce me to the Plague Lord! 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 I walked to another stall, I 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!"

Hum, [identifying bloodline·modification], or in other words, flame ion method...or is it called atomic spectroscopy? Used to measure metal ion content, 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 method is this?

No matter, I am the conductor of the experiment anyway, and I don’t need to do the work with my hands. All I need to do is look at the results they measured and see that they are pretty much the same...

"Little Gretel, which part are you responsible for?"

Seeing Gretel clasping his hands in front of his belly, dangling back and forth, looking like he was doing nothing, Elder Wood couldn't help but laugh and ask. Grete shrugged:

"I'll wait for them to get 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 looks too relaxed!

He didn't even take out his notebook!

The summary results will be calculated later, what should he use to calculate them!

Gretel silently took out the mobile version of Talling. In an instant, all the spell 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 the scene and began to work:

The collective use of magic can quickly produce grains in this field. Rooting, sprouting, emergence, tillering. Then, the growth process, like a fast lens, slowed down slightly...

"Stop, stop, stop! Sampling team, come in!"

It was a complete meal. The priests stood on tiptoe and filed away. There was a young priest whom Gretel was not familiar with. He was stopped in the middle of releasing his magic, and his breath choked on his chest on the spot. After coughing for a long time, he complained with tears in his eyes:

"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..."

"Hush!" 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 priest fell silent. The older man whispered:

"Besides, priests have priests' methods, and magicians have magicians' methods. Maybe they can do it?"

Then, the magic team came in for the second time to encourage the seedlings to grow. At jointing and booting, another soil sample is taken; at heading, flowering, grain filling, and maturity, the last soil sample is taken. The magicians responsible for the test were busy again.

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 them back one by one. The magician who was beaten back by him dared to be angry but dared not speak out, but he couldn't refute, so he had to work honestly. Only Elder Wood can make two jokes:

"Gretel, 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..."

Grete:......

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 cannot reach the shoulders and the lower part cannot 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 a chart. Tables, line charts, typed out in large sheets, Gretel immediately wanted to cover his eyes:

"Hmm... I look so tired..."

A table from Boss Boss, 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 pulled up again. Grete looked at them 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, and it won’t affect the harvest even if it’s a little bit.

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 -"

Wails were heard from all over the group of mages.
