Traduction de «coefficient de répartition matière organique-sol » (Français → Anglais) :

‘Organic soil improver’ means a soil improver containing carbonaceous materials whose main function is to increase soil organic matter content.

This might not work in the Lower Mainland because they already have a fair amount of organic matter in the soils, but here in the Okanagan and on the Prairies, there is a low level of carbon or organic matter in the soil.

Carbon is stored in the soil in organic matter, or what we call humus, and it is really a function of how much plant material goes in and the rate at which it decomposes out.

It transpires—and this I've examined in fairly good depth in the limited space provided in my written report—that the high-technology, high-intensive kind of agriculture is the very same one that provides for the highest level of degradation in terms of soil depletion, soil erosion, soil compaction, organic matter depletion, buildup of pests and diseases within the system, and harmful collateral effects upon other species, providing eventually for ecological imbalance.

RECOGNISES the vital role the soil plays as one of the three natural elements essential for life, as the physical support for a great number of human activities and its important functions including its huge richness of biodiversity and genetic variability, its capacity to store, buffer and filter water and other substances as well as its key role for biomass, food and raw materials production; NOTES that soil may not only be affected by climate change but it is also a storehouse for organic matter and that it has an important role in combating climate change; furthermore it has also important cultural and aesthetic values to be proper ...[+++]ly preserved;

My own research and colleagues have, over the last 10 years increasingly in Canada, looked at aspects of this, such as nutrient intensity, nitrogen and phosphorous loading, energy use in organic farming, soil and organic matter quality and quantity, biologic activity in the soil looking at various below-ground biodiversity, and soil health.
