- Abstract:
- In this diploma thesis, climatic relevant gases in the agriculture will be calculated with an agrarsoftware program which is called PlaneteGes. On the basis of model farms (fooder crop, cash crop and processing farm) in the research area of the foothills of the alps, which reflect the predominant types of farms (Bio/konv.) in the foothills of the alps, a nitrogen balance, a greenhouse gas as well as an energy balance were calculated for each model farm. In addition, the agricultural software program PlaneteGes and REPRO have been analyzed due to differences in the calculations of greenhouse gas emissions in the foothills of the alps. The calculated nitrogen balance shows that the conventional model farms who do animal husbandry are tending to have a nitrogen surplus and the organic model farms, because of missing mineral fertilizer applications on the fields, are tending to have a nitrogen deficit. In the soil, nitrogen surplus can lead to environmental problems whereas a nitrogen deficit can negatively influence the humus content in the soil and the soil fertility. The results of the greenhouse gas balance show that within each type of farm the conventional managed model farms emit more greenhouse gases than the biological managed farms. A greenhouse gas and energy balance enables the identification of emission sources and can be seen as a basis to reduce greenhouse gas emissions and to optimize the energy efficiency on the farm level. The results have shown tendencies in the amount of greenhouse gas emissions in the research area of the foothills of the alps as well as in the sources of greenhouse gases in the agricultural sector. Optimization measures on the agricultural sector are limited, but they are necessary to reduce the atmospheric CO2-concentrations and climatic changes. An efficient use of mineral fertilizers, pesticides as well as the carbon sequestration in the soil can have a positive influence on the greenhouse gas balance.
