Soil Humus Content

This trial (Filarski, 2016) from the Złotów district in Poland looked at the impact EM has on the humus content of the soil. EM was applied on crop residues (straw 100% plowed) over three years of application. This treatment was across 50 hectares with a large control area. After 3 years soil was tested for the humus content (sample 1 - EM, sample 2 - control).
