Okay kiddo, sodication is a fancy word used to describe a process of treating soil with a solution made from sodium ions.
So, imagine you have a garden where you grow plants. Sometimes the soil in the garden can become too acidic and not good for the plants to grow well. When this happens, you can add a special solution made by mixing water and sodium ions that helps to make the soil less acidic.
Sodium ions are like little helpers that work to balance the pH levels in the soil to make it just right for the plants to grow.
So when someone talks about sodication, they are really talking about using sodium ions to help improve the quality of the soil and make it better for growing plants. It's like adding some medicine for the garden so it can grow big and strong!
