ECOLOGICAL FOOTPRINT AS A METHOD FOR EVALUATION DIFFERENT AGRICULTURE PRODUCTION SYSTEMS

摘要

Ecological footprint could be a tool for evaluating impacts of different agricultural production systems (PS). Based on more years field experiments producing vegetables and field crops cological footprint of conventional (CON), integrated (INT), organic (ORG) and biodynamic (BD) farming systems in Maribor and CON, INT and ORG in Dolenci was calculated and interpreted using the SPIonExcel tool. Results showed a markedly lower ecological footprint of ORG and BD systems compared to CON and INT which are not significantlly different. Identified were possibilities for reducing ecological footprint – for CON and INT by reducing mineral fertilizers and pesticide inputs; for ORG and BD by changing fuels and reducing maschinery use.
