Fertilizer improves the number of bacteria that are able to use mineral forms of nitrogen and micellar groups of microorganisms in the soil. Indicators of the intensity of carbon dioxide emissions when using ammonium nitrate grade B indicates the level of overall biological activity of the soil and the processes that occur in it. Assessing toxicity of ammonium nitrate grade B in earthworms found that only at a concentration of 1000 mg / kg dry soil animals mortality was 6.2%. The medial concentration LC50 for the drug is 8064.5 mg / kg dry soil. Due to the fact that the rates of consumption of ammonium nitrate grade B in the field is - for the main application crops normally 60 - 120 kg / ha should be assumed that the concentration of ammonium nitrate grade B used for treatments below those that are toxic to earthworms Product Description popup.authors Бунас Альона Анатоліївна Довгич Катерина Іванівна Крижанівський А.Б.
