Emission load during growing of selected crops
 MRÁČKOVÁ, Jana
The thesis focuses on partial assessment of the life cycle of the strawberry plant (Fragaria), the breeding of which has a long tradition in the Czech Republic. The breeding technologies in conventional and ecological farming systems are compared, in relation to the greenhouse gases emission. The data from agriculture and transportation were accumulated by way of questionnaire survey and expert literature.The objective of this thesis was to assess the impact of individual agrotechnical factors on the pollution of the environment with greenhouse gases emissions in conventional and ecological farming systems, and also to test the hypothesis on whether it is better, from the environmental point of view, to consume locally produced or imported strawberries.The environmental impact was calculated with the SIMAPro software. This tool uses the Ecoinvent databases and enables to create a model of life cycle of the product in question according to the ČSN EN ISO 14040 and ČSN EN ISO 14044 standards. Theinputs and outputs were related to the unit of one hectare and the resulting value was converted as per 1 kg of strawberries. The input included technological operations, amount of fertilisers, and plant protection products; the output of the analysis was the emission load per1 kg of strawberries expressed in the CO2 equivalent.
