So one thing we could start to talk about is this concept of moisture retention curves. And a moisture retention curve is a graph, you know, it has, it has a y axis and an x axis. So you know, you're, you're vertically oriented y axis would represent your VWC, which is volumetric water content. So that's water as measured in the form of a percent. So how much water is in there, essentially, well, yes. And then, on a volumetric level, how much water is in there, and then that that brings with it all kinds of interesting correlations between air the amount of air. So as as water moisture, as volumetric moisture levels increase the amount of air in the soil decreases, right? And as that moisture, that volumetric water level decreases, your EC increases your electrical conductivity, or your parts per million, or however you want to how much material is in the in the water, usually in form of nutrients. That's going to increase as the amount of water in the soil dries out. And then, so that's your vertical axis. And then your horizontal axis is tension, and this is measured in center bars, or millibars, the units of pressure. One bar equals 15 psi. And that's, it's a metric unit, right? So, I never knew that for that formula. That's funny, yeah. So it's one atmosphere pressure, so it's like the weight of all the you know, how much that sea level, what does the all the air above you weigh with 15 psi or one bar, and if you break that down into metric fractions, so you have a steno bar is 1/100 and a millibar is 1,000th of a bar. So those are just units of pressure. So that's how you measure tension. There's a relationship between your VWC, your volumetric water content, your percentage, and the tension in the soil. And as the as the percentage of water drops in the soil, the tension increases, right? And you can, you can make a graph of this, and there's various functional points on the graph that are the set parameters for, basically, your your available water content. So there's a point at the graph where it's flat at the top, you know, it's very high percentage of moisture, and there's a certain point where it starts to fall now, so as the soil dries out, this graph is going to there's a point where the graph will drop. It's flat, and then it drops, and it goes straight down, you know, at some sort of angle. Is sometimes steep, sometimes less steep, depending on the soil moisture type, or, sorry, soil media type, and then it'll flatten out again.
