The Standard of Biomass Fertilizer’s Compost Degree

If fermentation products are not composted completely, using this kind of fertilizer will have a bad influence on growth of seedlings.

In mainland of China, there has been no standard for compost degree yet. In the countries that have standard, they’d love to use multi-indexes to judge the compost degree of fertilizer. Taiwan China and India just use   the ratio of C/N as index. Canada uses the ratio of C/N, germination rate and fermentation temperature as indexes. California of the United Stated uses more indexes to judge the compost degree of biomass fertilizer.
