Components of Dirt

Stones: Stones are solid mineral materials that are part of dirt. They can vary in size and composition, from small pebbles to large rocks. Stones can affect the texture and drainage of the soil.

Sand: Sand is another component of dirt. It is made up of small mineral particles and is often found in sandy soils. Sand can help improve drainage in the soil and affect its texture.

Clays: Clays are fine-grained mineral particles that can be found in dirt. They have a high water-holding capacity and can affect the fertility of the soil. Clays can become sticky when wet and hard when dry.

Humus: Humus is the organic component of dirt. It is made up of decomposed plant and animal matter and is rich in nutrients. Humus helps improve soil structure, retain moisture, and provides essential nutrients for plant growth.

Overall, the combination of stones, sand, clays, and humus creates a diverse and fertile environment for plant growth. Understanding the composition of dirt is essential for successful gardening and agriculture.
