A model laboratory experiment was conducted to investigate the transformation of postharvest residues of lucerne (Medicago sativa) and wheat as a source of soil organic matter. The results confirmed that the transformation of plant matter is a long-term one. Humified plant residues preserve both their outer appearance and anatomical structure for a relatively long time. Initial signs of the decomposition of the anatomical structure appeared only in the second year, their fragments being also observed during the third year of incubation. The transformation process of lucerne is more rapid and more intensive than that of wheat residues. In the third year of incubation, a time difference of approx equal to 200 days was observed in the accumulation of humus substances. The succession of changes and the formation of humus substances first of all depend on the composition of plant matter, the environment conditions, a length of vegetation, i.e. the ripeness level of plant residues, and on the thorough

ness of their mixing with soil. Microscopy enables a direct optical investigation of the transformation of plant matter, the decomposition of the anatomical structure, the formation of products and their accumulation, and the formation of humates on a level of microprocesses and their function in the given environment.
