Czynniki kształtujące efektywność gospodarstw ekologicznych o różnej wielkości

The article aims at presenting factors that determine the effectiveness of managing production resources in ecological farms of different size. Within the examined groups of diverse sized ecological farms, the technical infrastructure of land resources and the saturation of land with materials as well as the input of human labour per agricultural land acreage were clearly showing a decrease proportional to the increase in farm size, which was connected with the organization of production in the farms under examination. The organization of production in those groups of farms, the effectiveness of their production and the prices of organic products in the analysed years were reflected in the structure of the value of production of particular farm groups. Fruit and vegetables had a clearly higher and preponderant share in the value of plant production in 20-hectare farms, which mainly determined higher productivity of land and capital resources as well as profitability of smaller farms’ land resources.
