Abstract:
One of the main objectives of this diploma thesis is to assess various agricultural production systems, tillage systems (plough, mulch-till, no till), cultivation resistance and farm sizes according to their influence on the Cumulative Energy Demand (CED) of the production of winter wheat. The influence of the different production conditions has been quantified and the deviations have been discussed. Furthermore this work should help to assess the available production systems and to improve their energy efficiency. The concept of the Cumulative Energy Demand according VDI-guidline 4600 has been used to determine the amount of energy for production, maintenance and disposal of agricultural resources. The model has been created with the results of crop farming experiments and the assumption of the typical machine usage at the different tillage systems. The fuel consumption has been calculated by the help of the “KTBL-Feldarbeitsrechner”. The results are presented in two parts. One part deals with the energetic influence of the different agricultural resources, the other part presents the influence of the investigated main criteria on the energy efficiency. The diploma thesis shows that the Cumulative Energy Demand of the wheat production reaches from 7.500 to 16.500 MJ/ha. The Output/Input-ratio ranges between 6,5 and 15,0 and underlines the positiv energy balance of the wheat production of the treated conditions. The amount of fertilizer, fuel consumption and the indirect energy demand for the machine production are the greatest influence factors on CED in wheat production.
