In a healthy root system, what is maintained in relation to the above ground growth?

In a healthy root system, a balance is essential with respect to the above-ground growth of the plant. This balance refers to the relationship between the root system's ability to provide adequate water and nutrients to the plant and the amount of foliage and stems that need support. When roots are healthy and properly developed, they are capable of sustaining the photosynthetic demands of the leaves and the structural needs of the stems.

A well-balanced root system enables the plant to thrive since it ensures that there is sufficient support in terms of nutrient uptake and anchorage to support the biomass above ground. If the balance is off, such as when there are too many leaves relative to the root system or vice versa, the plant can experience stress, leading to stunted growth or other health issues.

In contrast, while connection, proportion, and strength all play roles in plant health, they do not encapsulate the dynamic relationship between roots and shoots as comprehensively as balance does. The term "balance" communicates the idea that both parts must work in harmony for overall plant health and growth.
