Neutralization of Peat for Substrates Preparation , Using Black Sea Organo-mineral Sediments (Sapropels)

Peat is a ground component in various substrates for seedling production. Because of content of organic acids in the peat it has to be neutralized before using. In the period May-June 2014 was carried out neutralization of peat from Lituania, using Black sea organo-mineral sediments – sapropels. The results obtained were compared to control – peat without sapropels and etalon – neutralized with powdered calcium carbonate peat. Incorporated in the peat the marine sapropels increase pH values as follows: At an amount 10 g/kg from pH 3.76 (control) to 4.85 at the first day, 5.24 after four days incubation, 5.41 after 11 days and 5.47 after 28 days. At an amount 30 g/kg at the same incubation periods to pH 4.92, 5.49, 5.77 and 5.93. At an amount 50 g/kg respectively to pH 6.37, 6.42, 6.47 and 6.58. At an amount 70 g/kg respectively to pH 6.90, 7.01, 7.18 and 7.23. At an amount 100 g/kg respectively to pH 7.08, 7.15, 7.19 and 7.28. By using calcium carbonate as etalon pH changes as follows: At an amount 10 g/kg from pH 3.76 (control) to 5.13 at the first day, to 5.33 after four days incubation, 5.42 after 11 days and 5.45 after 28 days. At an amount 50 g/kg respectively to pH 7.23, 7.27, 7.33 and 7.39. At an amount 100 g/kg respectively to pH 7.32, 7.41, 7.43 and 7.56, compared to control (pH 3.76)
