Soil
Soil is a crucial natural resource that plays a vital role in supporting life on Earth.
Funtion of Soil :
- Plant Growth: Soil provides a medium for plants to anchor their roots and obtain essential nutrients, water, and oxygen.
- Water Filtration: Soil acts as a natural filter, purifying and storing water as it percolates through the layers.
- Nutrient Cycling: Soil is a reservoir for essential nutrients like nitrogen, phosphorus, and potassium, which are cycled through ecosystems.
- Habitat: Many organisms, from microorganisms to insects and small mammals, live in the soil and contribute to its health and fertility.
Types of soil :
1. sandy soil : Sandy soil is soil that feels like beach sand. It's made up of tiny, loose grains and lets water flow through it easily. This type of soil doesn't have a lot of nutrients for plants.
2. Clay soil : Clay soil is soil that feels like sticky mud when wet and hard like a rock when dry. It's made up of very tiny, tightly packed particles.
3.loamy soil: Loamy soil is like the perfect soil for plants. It's not too sandy, not too sticky like clay—it's just right! Loamy soil is made up of a mix of small particles and it feels soft and crumbly. It holds water well but doesn't get too soggy, and it has lots of nutrients that plants need to grow healthy and strong.
4.Slity soil : Silty soil is soil that feels smooth and a bit powdery. It's made up of tiny, fine particles. Silty soil can hold onto water quite well, but it can feel a bit slippery when wet. Plants usually like silty soil because it has some nutrients, and it's easy to work with for gardening.
