ion-exchange capacity
Ion-exchange capacity refers to the ability of soil or other materials to hold and exchange positively or negatively charged ions, which are essential nutrients for plants. Think of it as a sponge that can soak up nutrients from water and release them as needed. Soils with high ion-exchange capacity can retain more nutrients, making them better suited for supporting plant growth. This property is important for agriculture, environmental science, and water treatment, as it affects nutrient availability and overall soil health.
