Licorice raised an eyebrow before remembering that yes, not everyone was fluent with lab management and methodology. It was still a bit of a weird concept for her, but she had to accept it. Then again, when someone thought about botany they rarely thought about a lab.
“Yes allow me to show you. Let’s take this box with samples from the native plant exhibit.” Licorice replied bringing one box to a small counter. On the right side of the counter was a song with a thin nozzle, a spray bottle labeled “50% isopropyl, 50% DI”, and chemwipes.
“This part is relatively simple. You take the probe, pull it out of its sheath, and check the sheath to make sure it isn’t contaminated. If you think it might be, spray the isopropyl mix into it, then rinse it with distilled water from this faucet.” Licorice pointed to the thin faucet.
“If it’s obviously dirty, it make take a while to clean but it’s in proper condition now. Non the less the most important part is the probe. Uncap a sample, keeping it in the box for organization, and slip the probe in. You’ll see a percent moisture and a pH on the screen momentarily.” Licorice showed the screen to the man. The probe itself was on a long wire that connected to the screen, so it wasn’t hard to demonstrate.
“Most soils need to be around 6.5 pH, just slightly acidic. That’s where levels of various nitrogen compounds are abundant enough to keep plants healthy without accidentally killing them. Since pH can change within a few days depending on fertilizers, we do this roughly once a week.” The screen ready 6.43 pH, which was good for Licorice. She removed the probe, sprayed it with the isopropyl mix, wiped it down with a chem wipe, and rinsed it with DI water before wiping it down one more time. She then inserted it into the next sample.
“Just make sure to write down the results in the book here.” Licorice instructed, giving the man a pen and showing him the book. Everything was prelabeled and matched the markings on the tubes and boxes. “Percent moisture is not as important as it’s mostly checking if the irrigation systems are working properly, but each soil, depending on the plants, needs different levels but I’ll compare them for now. You shouldn’t need to worry about that.”
[✿] — Raguna nods as she goes through her explanation, not finding it too difficult to get a handle on. It didn’t seem too hard, but that didn’t mean he would take it easy, either. It was important work, and he didn’t want to mess it up.
“Okay, I got it.” Just slip the probe into the samples, make sure everything was clean, and record the respective pH level for each one. Yeah, he could do this. “Thanks! I’ll be sure to ask you anything else if I need... if that’s alright, of course.” She seemed pretty busy, after all.
