Biological Properties

Several functions depend on biological activity: transfers of nutrients from the soil to the plant, dissolution of minerals from the bedrock, mineralization of organic matter, stabilization of the soil structure by synthesizing organic substances, cohesion of the aggregates and creation of galleries to aerate and create porosity. Biological activity has direct consequences on the physical and chemical properties of soils.

Quantification and qualification of biological activity is essential to optimize the potential of soil and plants.
Soils contain more than a quarter of all species living on Earth. There are no less than 260 million individuals by square meter of soil, that is, a global mass equivalent to 12 adult cows per hectare. A diverse and varied community of soil organisms is working day and night in a remarkable effort of coordination that allows life on Earth.
In an area of the size of a football field, the soil organisms produce each an amount of humus that can be equivalent to that of 25 cars.
