The aim of the analysis was to present conditions and relationships which shape remuneration of labor in agriculture, taking into account human capital. Understanding these relationships is crucial for the income of agricultural producers. An analytical approach with elements of empirical verification was used, the reasoning is carried out in the microeconomic convention. On the basis of a preliminary empirical verification, it was found that in Poland labor forces, salaried within the agricultural production, decreased substantially. This may indicate the increasing use of labor resources in rural areas beyond agricultural production.
