In France, the most important sources of organic amendment are manure and compost. Compost is, however, poorly developed in France, and to ensure its development it is important to determine when organic matter really has a positive effect on French soils. For loamy soils, a decrease in organic matter below a threshold of 2 – 3 % is one of the main controlling factors in soil physical degradation like crusting and erosion.
