What does Field Capacity really mean?

Hey there! So, "field capacity" is a term we use to talk about how much water the soil can hold after it's been thoroughly soaked but has had a chance to drain. Think of it like a sponge - when you put the sponge under the faucet and it's full of water, that's like the soil being completely soaked. But then when you squeeze the sponge a little and some water comes out, that's like the soil draining. The amount of water left in the sponge after you've squeezed it is kind of like the field capacity of the soil.

In more scientific terms, field capacity is the maximum amount of water that the soil can hold against the force of gravity. That means that once the excess water has drained away, the remaining water is held in the soil by other forces, like capillary action and surface tension.

It's an important concept for understanding how plants get their water, because it helps us know how much water is available to the plants in the soil. If the soil is at field capacity, that means the plants have access to water, but if the soil is too dry or too wet, the plants might not be able to get the water they need to grow.

So, in a nutshell, "field capacity" is all about how much water the soil can hold after it's been soaked and then allowed to drain, and it's super important for understanding how plants get their water. Does that make sense? Let me know if you have any questions!
