摘要
Within two different cropping systems, the so-called integrated (A) and organic (B), and three modelling crop rotations, were studied for analysis of energy and material inputs and outputs. It can be seen from results obtained, that integrated system is more energy-demanding, on average 23,65%, comparing to organic system (Tab. II, Fig. 1) when biomass production was analyzed. Organic system showed higher biomass productivity (5,48%) comparing to integrated system, despite the fact, that no synthetic fertilizers and pesticides were applied to organic system (Tab. II, Fig. 3). Other energy evaluation as energy efficiency and relative energy used are more preferred in organic system (Tab. II, Figs 4, 5). Where utilization of solar radiation in photosyntetic process was studied, organic system had better results, higher on average by 9,41% comparing to the integrated system (Tab. II). From the total energy evaluation of studied systems, especially analysis of dose energy inputs, can be concluded, that organic system showed better energy performance in comparison with integrated system. The possibilities of energy saving are not only in rationalizing of production processes but also depend on biological stability of cropping system.
