The work study presents the size and the structure of raw-materials and goods flow in agricultural farms with regard to the production trend. The assumed aim was carried out based on research conducted in 80 farms of Southern Poland. The facilities covered by the research were divided into four groups: one-trend farms - plant and animal production oriented, two-trend farms and mixed - trend farms. As a result of the research which was carried out, the size and the structure of raw materials and goods flows was assessed within main areas of logistics: supply and distribution. Forming models of raw materials and goods flow in the researched farms, which illustrate the size and the structure of goods mass flow, was the final effect of the research.
