The survey was performed with the method of direct interviewing in the years 2009-2014 in 160 randomly selected both organic and conventional farms participating in the agro-environmental programme PROW 2007-2013. The farms were situated in Czarnkowo-Trzciana, Piła and Złotów counties of Wielkopolska Province and in Wałcz County of Zachodniopomorskie Province. Farm size, the structure of agricultural lands, crop structure in arable lands and the area of orchards were determined based on performed interviews. The number of agro-environmental packages realised in farms and the amount of financial support obtained by this way were analysed. There were markedly more farms realising organic farming package. Organic farms had the area of agricultural lands similar to that in conventional farms. Permanent grasslands had a significant share in the structure of agricultural lands of farms in both production systems. The share of permanent grasslands increased with the area of agricultural lands and reached 50% in the largest organic farms. Remarkable differences were found in the crop structure of arable lands. Fodder crops and orchards dominated in organic farms and cereals - in conventional farms. Oil and tuber crops were important in the largest conventional farms. Analysis of the number of realised agro-environmental programmes did not show quantitative differences but revealed clear qualitative variability. In organic farms, the organic farming package was accompanied by “biological” packages like grassland management and preserving endangered genetic resources of plants in agriculture while in conventional farms - sustainable agriculture and soil and water protection with substantial contribution of “biological” packages associated with grassland management. Performed studies showed a higher interest in the organic farming package among farmers participating in agroenvironmental programme and a greater support obtained through realisation of the programme within this package.
