Abstract: The article presents analysis of organic farming, in which quality of organic production is problematical question and asking different field testing. Investigation on potato fertilizers composed of the combination of phosphorus and potassium were carried out in 2007-2008 in the Experimental Station at Aleksandras Stulginskis University and in 2010 investigation on applying biological preparations to organically grown potatoes was carried out on V. Elzbergas‘s farm of organic production in Kelme district. Results show, that treating potatoes with a combination of potassium and phosphorus fertilizers and potassium fertilizers alone significantly increased total and marketable yield of organically grown potatoes. Phosphorus and potassium fertilizers had little effect on the output of marketable yield of potatoes. Energetic P value increased under the influence of combination of phosphorus and potassium fertilizers and this shows lower suitability to human body. Treating potatoes with biological preparation in their growth technology did not allow determining their total and marketable yields. Biological preparations had a positive effect on energetic values of potatoes- lower values were calculated and this shows greater suitability to human
