Compost is a poor source of these substances, which any commercial soil lab can verify by doing a humic acid extraction and assessment. Carbon is a chemical element having the atomic number 6. A relationship established between N and C losses indicated that 85% of the initial total N of the compost was available for microbial degradation and that 70% of the available C was lost as CO 2 during the immobilization process. … Pour que le compostage se fasse dans des conditions optimales, le bon rapport Carbone/Azote doit être de 20-30.
