A
Humification
B
None of these
C
Leaching
D
Fragmentation

Decomposition in soil results in humification and mineralization. Humification refers to the accumulation of dark coloured amorphous substance called humus which serves as a reservoir of nutrients. It resists microbial action and so decomposition takes place very slowly. Further degradation of humus by microbes leads to mineralization.
