Biomass of intercrops as a source of lignin as a precursor for the formation of humus substances in the soil

Popis výsledku v původním jazyce

Disintegrating plant residues rich in cellulose and lignin which are substances naturally resistant to microbial decomposition form an important part of soil organic matter (SOM). Yet, the degradation of lignin can start already in the initial stages of decomposition if the soil contains a sufficient amount of readily available saccharides that serve as an immediate source of energy for microorganisms to which they allow to produce enzymes necessary for lignin decomposition.The aim of this study was to monitor changes in the content of simple sugars and lignin in the biomass of intercrops during their vegetation of the ten intercrop species: Watercress, Oil radish, White mustard, Purple tansy, Crimson clover, Millet, Safflower, Buckwheat, Fenugreek and Hungarian vetch. The highest sugar to lignin ratio was recorded in Oil radish (7.20% DM) and Watercress (3.97% DM). For comparison - traditionally used farm fertilizers contain significantly more lignin: 15.03 % DM in cattle manure and 13.05 % DM in horse manure.
