Název v původním jazyce

The influence of agricultural management on soil organic matter quality in long-term field experiment

Popis výsledku v původním jazyce

The content of aliphatic compounds, hydrophobicity index, C and N content in soil samples from the long-term field experiment with different fertilizations and crop rotations were determined. To complete the data the biomass and basal respiration were measured. Four variants (nil x no fertilization, NPK x mineral fertilization, FYM - farmyard manure and FYM+NPK) from three blocks (III, IV and B) with different crop rotation have been selected for this study. The variants without any fertilization had the significantly lowest aliphatic compound content compared to variants fertilized by FYM or FYM+NPK in all the evaluated blocks. The aliphatic compound contents highly correlated with the organic C contents (Cox) . Organic manure increased the soil organic nitrogen content. In variants fertilized by FYM and FYM+NPK the higher microbial biomass content was found comparing to unfertilized variants. Organically fertilized variants had increased basal respiration, similarly to the aliphatic
