Quantity and quality of soil organic matter in long-term field experiments in Prague

Popis výsledku v původním jazyce

This study assesses the effect of long-term application of organic and inorganic fertilizers on soil organic matter in two different field experiments. Total organic C, hot water soluble C and microbial biomass C were determined during the time in soil samples. In bare fallow experiment, organic fertilization caused initially a significant increase in organic C in the soil, followed by later stagnation. After termination of organic fertilization, C content declined slightly but after switching black to green fallow organic C content in the soil was again increased, even in organically non-fertilized variants. In second long-term experiment with continual fertilization and regular crop rotation, mineral NPK fertilization influences the soil organic matter content indirectly via increased crop residues incorporation and is less useful. However, long-term application of farmyard manure or compost possibly supplemented with NPK is the most beneficial, it delivers organic matter to the soil and extends carbon sequestration.
