Abstract: Not only in Lithuania, but also in the European Union, one of applicable means for environment protection is organic farming. The direction of organic production in agriculture ensures safe nutrition because it reduces the use of fertilizers and consequently the pollution of environment: food quality is improving, soil remains biologically active and natural balance is maintained. Investigation of the effect of organic nitrogen fertilizer Provita and fermentator of organic matter Penergetic-k on organically grown winter wheat and soil was carried out in 2006-2008 on the farm of organic production of The Center of Agroecology at Lithuanian University of Agriculture. As the outcome of research it was determined, that spraying .soil with Pencrgetic-k and Provita resulted in an essential increase of winter wheat productivity compared to either spraying with Penergetic-k or application of Provita alone; essential increase in the amount of proteins compared with application of Provita alone; essential increase in the amount of green fiber, compared with spraying with Penergetic-k alone; essential increase in the amount of phosphorus compared to untreated wheat. Penergetic-k and Provita did not have essential effect on the amount of gluten, index of sedimentation, amounts of potassium, magnum and calcium in organically grown winter wheat. Spraying soil with Penergetic-k and application of Provita resulted in the essential decrease in grain and soil pH value, compared to spraying soil with Penergetic-k alone; essential decrease in redox potential compared with untreated wheat. Application of Provita fertilizers to winter wheat essentially increased the value of grain and soil specific electric conductivity, compared with spraying soil with Penergetic-k or application of combination of Penergetic-k and Provita fertilizers
