Understanding Different Types of Soil

The video tutorial introduces the different types of soil: sand, silt, clay, and loam. It explains the characteristics of each type, including particle size, water retention, and suitability for plant growth. Sand has large particles and drains water quickly, making it unsuitable for plants. Silt, deposited by rivers, holds some water. Clay has the smallest particles, retains water well, but can hinder plant growth. Loam, a mix of sand, silt, clay, and humus, is ideal for gardening due to its balanced properties. Humus, composed of decayed organic matter, enriches soil fertility.
