Intensity of agricultural farming influence use of energy dissipation, water cycle, nutrient cycle and environmental pollution. Five farms with different land areas and farming intensity from 2004 to 2005 were compared for energy and carbon budgets in the upper Stropnice river watershed (99 km2). Costs include the energy of human work, fossil fuels, electricity, machinery, buildings, mineral and organic fertilizers and pesticides. Yields include products of plants or livestock production. Concerning the energy budget, the plant production of all farms had positive results, whereas their livestock production results were only slightly positive. The main energy outputs in the livestock budget were heat of production (39% of total) and manure energy (46% of total). The largest part of the energy reserves consisted of plant energy (80% of the total). The main carbon outputs in the livestock budgets consisted of respiration (38% of total) and manure carbon content (53% of total).
