The possibilities of bioenergy production in a chosen agricultural farm in higher elevations
BÁRTA, Pavel
The chosen agricultural enterprise, Agricultural Cooperative Skalka {--} Jankov farms in the South Bohemia region near the city of České Budějovice. Analysis of the inner structure of the agricultural system was calculated for a ten-year period 1998 {--} 2007. Data used for the analysis include: harvest area, yield of individual crops, mineral fertilizer consumption and cattle stock. On the basis of this analysis, using carbon balance principles, variants of agricultural inner structure project have been worked out, aimed at bioenergy production: cereals for production of bioethanol, raps for biodiesel production, biogas.

System analysis of agriculture enterprise on bioenergy production in foothills
HAMBERGEROVÁ, Jana
Chosen agricultural enterprise Agricultural-Trading Cooperative Farm operates 20 km away from České Budějovice in South Bohemia Region. Analysis of inner structure of this farm was performed for period 1997 {--} 2006. To project inner structure of the agricultural system, it is necessary to know the harvest area and yield of individual crops, cattle stock, and mineral fertilizer consumption. On the basis of performed analysis, using carbon-balance method, projects of inner structure specialized in bioenergy production were calculated. The production of bioethanol from cereals, oil from rape and biogas from cattle breeding refuse are taken into account. At comparison of individual variants from aspect of energetic gain under existing natural conditions, the variant specialized in cereals for ethanol production proves as the most suitable.

System analysis of chosen agricultural farm at higher location at orientation on bioenergy production
ŠIMEK, Michal
Chosen agricultural enterprise Agricultural Cooperative Slapy u Tábora farms in the South Bohemia Region near the Tábor city. Analysis of inner structure of this farm was worked out for the period 1996 {--} 2006. Harvest area and yield of individual crops, mineral fertilizer consumption and cattle stock have been used for the analysis. On the basis of performed analysis, variants of inner structure have been calculated, aimed on production of bioenergy: cereals for bioethanol production, raps for biodiesel production, biogas. From aspect of energetic gain, the variant for bioethanol production was evaluated as optimal.
