The testing was carried out at the State Stende Cereals Breeding Institute from 2011 to 2012. The aim of the study was to identify the biological activity of soil in potato plantation by using extracts from organic products in two cultivation systems: conventional and organic. The following extracts from organic products were used: peat elixir and vermicompost extract obtained at +45° C. The study was carried out in the potato plantation with the variety ‘Borodjanskij rozovij’. The extracts from organic products, peat elixir and vermicompost extract, tended to have a positive impact on a number of microorganisms in the soil both in organic and conventional cultivation systems in the potato plantation. However, the tendency was observed that the number of microorganisms in the conventional cultivation system was higher than that in the organic cultivation system. The research findings showed that the number of microorganisms was higher at the end of the summer and when the tubers were treated before planting in nearly all extract application options.
