What is soil?

Soil is like a big, cozy blanket that helps plants grow strong and happy.

Imagine you're playing with your favorite sandbox. You dig in it, make castles, or hide treasures, the sand is soft, but it's also full of little bits of stone and other stuff mixed in. Soil is kind of like that sandbox, but much bigger and more special. It’s made up of tiny pieces of rock, bits of plants that have died and turned into dirt (we call this organic matter), and even some living creatures like worms and bugs.

What Makes Soil Feel Right?

Soil isn’t just one thing, it has layers, kind of like a cake. The top layer is usually the softest and most full of life, while deeper down, things are harder and less busy. This is called soil structure, and it helps water and air move around so plants can drink and breathe.

Sometimes, soil feels dry and crumbly, like when you leave your cookie dough out too long. Other times, it’s wet and muddy, like after a rainstorm, just like the ground under your feet when you run through puddles!
