Which component is critical in determining soil health?

Nutrient levels are a critical component in determining soil health because they directly influence the ability of plants to grow and thrive. Adequate nutrient availability ensures that plants have the essential elements they need for key processes such as photosynthesis, root development, and flowering. Soil with balanced nutrient levels promotes healthy microbial activity, enhances soil structure, and supports overall ecosystem functionality.

While water content, soil depth, and slope angle can also impact soil health and plant growth, nutrient levels specifically dictate the biological activity and chemical fertility of the soil. Without sufficient nutrients, even well-drained, deep, and well-structured soils may fail to support robust plant growth. Hence, focusing on nutrient levels provides a more direct link to the overall vitality of the soil and its capacity to sustain agricultural or horticultural endeavors.
