Okay kiddo, let me explain what dispersion in soil means.
So, do you know that soil is made up of different types of particles like sand, silt, and clay? When you mix water with soil, these particles tend to stick together and form clumps.
But sometimes, the water breaks down these clumps and separates the particles. This is called dispersion. When this happens, the clay particles become suspended in the water and create a cloudy appearance. This can cause problems for plants because it becomes difficult for the roots to absorb nutrients and water from the soil.
Think of it like a chocolate chip cookie mix. When you add water, the dry mixture combines to form cookie dough. But if you keep adding water, it becomes too wet and the chocolate chips start to separate from the dough.
Similarly, when too much water is added to soil, the particles start to separate and cause dispersion. This can be a problem for farmers and gardeners who want healthy plants to grow.
I hope that helps you understand what dispersion in soil means!
