The basic objective of the paper is the analysis of nutrients balance in 4 selected ecological farms, which are characterized with a similar acreage (approx. 5 ha AL) and a varied production trend and equipment with mechanical tractive force. Fertilizer management in the sustainable production system has to satisfy nutritious demands of cultivation plants and to support or improve the soil fertility. Skilful use of resources of habitat shall allow obtaining good production results at possibly lowest consumption of fertilizers. At the uptake of fertilizer components, we may notice that the highest index of nitrogen uptake occurs in the animal production farm B (-188.8 kg· ha -1”) and in A2 orchard plant production farm (-168.6 kg· ha -1”). By analogy, it also concerns phosphorus and potassium uptake. Despite introduction of these components to soil, NPK balance in all farms was negative. When analysing power distribution, both in the general as well as unitary view, one may notice that the single-polar field plant production object (A1) was characterised with the highest power installed in tractors - 38.2 kW. Whereas, a single-polar orchard plant production object (A2) with the lowest index -18.4 kW.
