🌍 What is Soil? Soil is the top layer of the Earth’s surface, made of minerals, organic matter, water, and air. It supports plant growth and is the base of agriculture, forests, and life on land. 🧩 Composition of Soil Soil is made up of four main parts: 1. Minerals (45%) – tiny particles from rocks (sand, silt, clay). 2. Organic Matter (5%) – decomposed plants, animals (humus). 3. Water (25%) – moisture that plants use. 4. Air (25%) – oxygen & carbon dioxide for roots and organisms. 🌱 Soil Types (based on texture) 1. Sandy Soil – Large particles, drains quickly, poor in nutrients. 2. Clay Soil – Very fine particles, sticky, holds water, rich in nutrients but poor drainage. 3. Silty Soil – Smooth, soft, retains water better than sand. 4. Loamy Soil – Best for farming; balanced sand, silt, clay, and humus. 5. Peaty Soil – Dark, rich in organic matter, acidic. 6. Chalky Soil – Alkaline, stony, drains well but poor for some crops. 🌏 Soil Layers (Soil Profile) 1. O Horizon – Top org...
