What percentage of organic matter should ideally compose soil?

Soil composition plays a crucial role in plant health and growth, and organic matter is a key component in creating fertile soil. Ideally, soil should contain about 5% organic matter. This percentage is significant because organic matter improves soil structure, enhances water retention, provides essential nutrients, and promotes beneficial microbial activity.

Organic matter primarily comes from decomposed plant and animal materials, which contribute to the soil's fertility and its ability to support various forms of plant life. Levels much below this ideal can lead to poor soil structure and reduced nutrient availability, while levels significantly above can cause issues like compaction or nutrient imbalances. Thus, maintaining around 5% organic matter is generally understood to provide the best environment for healthy plant growth.
