Soils

Soils are the upper layer of the Earth’s surface, made up of minerals, organic matter, water, and air. They are crucial for plant growth, serving as a habitat for countless organisms. Soils form through the weathering of rocks and the decomposition of organic matter over time. Different types of soil vary in texture, pH, and nutrient content, influencing what can grow in them. Healthy soil is vital for agriculture, as it supports food production and helps manage water and carbon cycles. Understanding soil helps us appreciate its role in ecosystems and sustainability.
