Not diseased or infirmed (i.e. not degraded, nor degrading), nor causing negative off-site impacts;
Soil retrogression and degradation are two regressive evolution processes associated with the loss of equilibrium of a stable soil.

Soil biodiversity

biodiversity
Soil health depends on soil biodiversity (with a robust soil biota), and it can be improved via soil conditioning (soil amendment). Sustaining plant and animal productivity and biodiversity (Soil biodiversity);
Well-developed, healthy soils are complex systems in which physical soil structure is as important as chemical content.

Humus usually constitutes only five percent of the soil or less by volume, but it is an essential source of nutrients and adds important textural qualities crucial to soil health and plant growth.

Soil resilience

Soil resilience
Soil resilience refers to the ability of a soil to resist or recover their healthy state in response to destabilising influences.

Soil water (retention)
Much of this retained water can be used by plants and other organisms, thus contributing to land productivity and soil health.

The condition of this capacity is termed soil health, a term that communicates the value of understanding soil as a living system as opposed to an abiotic component.

Soil health cannot be ignored as a valuable and extensive activity for the management of dryland salinity – the multiple benefits of improving soil health are clear and can be motivated by the potential for local and regional economic and social gains.

Maize

The primary difference between the two expressions is that soil quality was focused on individual traits within a functional group, as in "quality of soil for maize production" or "quality of soil for roadbed preparation" and so on. The addition of the word "health" shifted the perception to be integrative, holistic and systematic.

It turns out that soils highly fertile from the point of view of crop productivity are also lively from a biological point of view.

If this is consistently true, than the prevailing Liebig nutrient theory model, and Mitscherlich modifications of it, all which exclude biology, are perhaps dangerously incorrect for managing soil fertility sustainably for the future.
