Özet
This research was carried out in order to determine the most suitable method for chemical extraction of available zinc (Zn) content in paddy soils for plants in the Thrace Region. As a result of the investigation with 12 paddy soils representing the region, the effect of the application of increasing amounts of zinc (Zn) to the soil of pot-grown maize on increasing the zinc (Zn) uptake by the plant, amount of dry matter, and zinc (Zn) content in the plant was determined. Nine chemical extraction methods for available zinc content of soils were used, and the reliability of the investigated methods was ranked as 0.005 M DTPA + 0.01 M CaCl2 + 0.1 M TEA > 0.005 M DTPA + 1 M NH4HCO3 > 0.01 M Na-2 EDTA + 1 M (NH4CO3 > 0.01 N Na-2 EDTA + 1 N NH4 OAc > 0.01 N Na-2 EDTA > 1 N NH4OAc > 2 N MgCl2 > 0.05 N HC1 + 0.025 N H2SO4 > 0.01 M Hidrocinon. The method for extraction with a 0.005 M DTPA + 0.01 M CaCl2 + 0.1 M TEA solution, which not only has the highest correlation coefficient (r) but also enables determination of Fe, Mn, and Cu concentrations in addition to Zn amount, can be recommended as the most suitable method for the soils investigated.
