Private farming is the dominant mode of agricultural production in most European countries. Not all farmers are equally successful, economically. In this paper it is analysed whether social capital is an important factor contributing to higher agricultural incomes. Based on the findings of a farm survey in Poland among 410 farmers by adopting factor and multiple regression analysis it can be deduced that social capital is indeed a significant factor determining the level of agricultural income. However, its impact not that clear-cut as anticipated. More in-depth analysis will be needed in the future.
