Biogas digestate as an effective means to improve the physical properties Cambisol

In the submitted diploma thesis the theoretical part is just an overview of basic information concerning anaerobic digestion, and thus about biogas production, principles of its origin, chemical composition, properties and requirements regarding the soil out of which the biogas comes into existence in fermenter biogas stations. The other part of the theoretical section deals with digestate and types of soil since the aim of my thesis is the monitoring of possibilities how to utilize the waste from BGS fermenters, digestate for composting and how to improve physical-chemical properties of heavy soils. It was proved in the experimental thesis itself that the digestate is not organic fertiliser, on the contrary it is weak mineral fertiliser, highly diluted, and it does not fulfil the role of organic fertiliser because its organic substance is too stable. However, it can be successfully used during the digestate application into the compost ? it is earth-friendly and airy substance, it prevents heat leakage and the compost has higher T-value. It is suitable for the application into soil ? not as an organic fertiliser but for the improvement of water-air mode of soils, especially those heavy ones
