What is Von Post scale?

Von Post is a degree of decomposition method. It does not directly determine fiber content but determines degree of decomposition on a 1 to 10 scale. • For many/most applications and interpretations however, fiber content and degree of decomposition are closely correlated.

How many Histosols are there in the world?

Histosols comprise only a small portion of the world’s land area (1.2%), but are widely distributed irrespective of climate.
