Due to progress of ecological farming the breeders and farmers need to know how to store ecological cereal seed material. Investigations on the seed storage value of ecological and conventional seeds were performed on naked and hulled oat during 5 years of storage in a granary and long-term store. There were analysed germination capacity, mean germination time, vigour by the growth test according to ISTA method and response to drought stress. It was found that germination capacity and vigour were lowest for the organic seeds of cv. Polar stored in a granary. In the hulled cv. Krezus degradation process was delayed. In case of long-term storage, seed value was retained irrespective of the cultivar or method of cultivation. The highest response to drought stress occurred in organic seeds of cv. Polar taken from a granary. The response to drought stress of the hulled cv. Krezus was lower irrespective of method of cultivation.

Negative impacts from application of fertilizers and pesticides in agriculture have been observed since the mid-20th century, when their use rapidly increased. This led to decrease in the number of species connected to the agricultural landscape. So-called integrated farming practices are currently being introduced that aim to mitigate negative impacts on the environment and to stabilize the numbers of wild flora and fauna. A number of studies have examined the positive influence of integrate and organic farming as modern agricultural practices in a European perspective. The positive impact of these practices is particularly evident in plants and invertebrates studied in Italy, Austria, Germany and the UK, for example. There is little such data from Central and Eastern Europe, however, even as the region has specific environmental conditions due especially to the more moderate impact of agriculture there during the second half of the 20th century. In this study, we compared the numbers of herbal and bird species on crop fields and meadows managed with conventional versus integrated systems in Southern and Central Bohemia, the Czech Republic. Our analysis included also the effects of land parcel size, position within these parcels and presence of other habitat elements (ditch, tree, field roads, dunghill, field margins – boundaries, bushes, fallow area) in the vicinity of study plots. We found that herbal communities were significantly more species-rich on lands with integrated farming and similar results were obtained in the case of birds, except there was a non-significant effect of integrated farming on bird species richness in meadows. In addition, the species richness of plants decreased as land parcel size increased. In conclusion, herbal and bird communities were shown to benefit more distinctively from integrated farming in Central Europe, where this effect is not considered unambiguous due to the higher overall habitat heterogeneity and historically lower burdening of farmland with pesticides and fertilizers. The results support the idea that it makes sense even here to introduce integrated forms of agricultural practice.

In Poland in the year 2010, 518 527 hectares of agricultural land were managed organically. This study attempts to estimate the total non-monetary value of Polish organic production as a sum of its non-monetary external benefits and the external costs which were offset by the transition from conventional to organic production. The external costs of Polish conventional agriculture were also calculated and a comparison with existing available data from Germany, the UK and the USA was made.

The selected nutritive components and level of contamination with nitrate and nitrite in three varieties of potatoes and carrots from conventional and ecological farms were determined. Potatoes from ecological farm contained move dry solid, starch and less vitamin C in comparison with conventional. All investigated varieties of carrots from ecological farms contained more dry solid, total sugars and less total carotenoids than conventional products. The higher content of nitrates was found in vegetables from conventional farms. Levels of nitrites in ecological and conventional agricultural products were similar - above 1 mg NaNO2/kg.
