Which method can be used to assess soil health?

Assessing organic matter content is a fundamental method for evaluating soil health. Organic matter plays a crucial role in maintaining soil structure, fertility, and moisture retention. It contributes to the overall biodiversity of the soil ecosystem and supports microbial life, which is vital for nutrient cycling and plant growth. Higher levels of organic matter typically indicate healthier soils, as they enhance the soil's ability to store water and nutrients, improve aeration, and promote resilient ecosystems.

While measuring the thickness of soil layers, counting earthworms, and evaluating plant types can provide insight into certain soil characteristics or environmental conditions, these methods do not directly reflect the comprehensive health of the soil in the same way that organic matter assessment does. Each of those methods can serve as supplementary indicators in a broader assessment of soil health, but the presence and amount of organic matter is considered one of the most reliable and indicative measures of soil vitality and functionality.
