Srovnání vlivu biologických odpadů rozdílné kvality na biologickou aktivitu půdy

This master thesis analyses the topic of soil biological activity after the addition of biodegradable waste of different quality (straw, grass, compost). A container experiment with a goal to determine the influence of fresh organic matter and stabilized organic matter on soil biological activity is a substance of this thesis. Soil biological activity was interpreted by soil gas production, namely CO2 and N2O, also by determining the number of microorganisms of individual physiological groups, by determining the cellulite organism activity and by assessing the growth of the indicator plant biomass. It was discovered that a material containing less degradable substances and a broad C/N ration (straw) can cause the depression of plant growth compared to application of stabilized organic matter (compost). However, if the applied fresh organic matter has a suitable composition and an optimal C/N ratio, it can be incorporated into the soil without prior stabilization, for example by composting, and it still may have a positive impact on growth of biological activity of the soil biota and it may positively affect the plant growth at the same time
