Understanding Garden Soil: The Basics
Garden soil is not just dirt. It is a living ecosystem that supports your plants’ growth by providing essential nutrients, retaining moisture, and allowing for gas exchange. Healthy soil consists of a mixture of minerals, organic matter, water, and air. There are several key components to consider when determining what to use for your garden soil.
Components of Good Garden Soil
Mineral Content: Soil is primarily made of minerals. The three main types of soil minerals are sand, silt, and clay. The proportions of these minerals determine your soil’s texture and drainage capabilities.
Organic Matter: This includes decomposed plant and animal matter. It enriches the soil, improves its texture, enhances moisture retention, and provides vital nutrients to plants.
Soil Microorganisms: These tiny creatures, such as bacteria and fungi, play a significant role in breaking down organic matter, making nutrients available for plant uptake.
Water: Plants need water to survive and grow. Well-draining soil holds enough water for root absorption but also allows excess water to drain away to prevent root rot.
Air: Proper aeration is essential for healthy root development and microbial activity. Compact or poorly drained soils can hinder plant growth.
