Özet:

 


The water content near saturation during the winter times reduces the redox potential of soils this in fact cause changes in nutrient element concentration induced by sampling time. The availability of iron (Fe) and manganese (Mn) prone to very large variations depending on redox induced reactions upon depletion of oxygen diffusion into soils. Thus we aimed to investigate how available Fe and Mn concentrations are affected by saturation-time and soil properties. For this purpose total of 15 surface soil samples (0-30 cm) with differing physico-chemical properties were incubated at near saturation condition by mixing 1:1 soil: water and constant temperature (22±2°C) for 91 days. pH, oxidation reduction potential (ORP), DTPA-Fe and–Mn were measured on 3, 7, 14, 21, 31, 45, 60 and 91st days. Results indicated that redox potential had significant effects on DTPA extractable Fe and Mn concentrations. These changes were function of soil properties and incubation period. It can therefore be concluded that it is beneficial to include the ORP measurement into routine soil analyses parameters to better evaluate the available Fe and Mn concentration of the same field’s soil sampled at differing time or season.
