<p>Soil organic matter (SOM) represents one of the largest and most important reservoirs of organic carbon in terrestrial eco-systems.

The effect of amending soil with different organic and mineral fertilisers was studied. Qualitative parameters of SOM, soil reaction, and the content of available nutrients (N, P, K, Ca, Mg) were followed.
