Abstract EN
Understanding the distribution of zinc (Zn) fractions in soils is important for effective and efficient management of the fertilizer resources given world-wide, limitations of crop production and food quality by insufficient Zn.
This study was undertaken to evaluate the chemical speciation and distribution of Zn in soils of Homs Governorate.
Sequential extraction scheme was used to fractionate Zn into exchangeable bound to carbonate, organically bound, bound to manganese (Mn) and iron (iron) oxide, and residual forms, Total soil Zn ranged from 56.7 to 460.460 mg kg- 1 with an average of 136.33 mg kg- 1.
The distribution of Zn fractions in the soils on the basis of average concentrations was in the order.
Residual (72.14 %) > oxide bound (22.78 %)> organic bound (2.40 %) > carbonate bound (2.24 %) > exchangeable (0.43 %) Data shows that percentage of potentially available fraction of Zn was highest in soils of second agricultural stability areas (35.35 %) and lowest in fourth(15.057 %) Correlation analysis showed that total Zn, bound to carbonate, bound to manganese (Mn) and iron (Fe) oxide and organically bound increased with soil organic matter, Zn bound to organic decreased with pH (r =-0.353), and calcium carbonate (r = -0.350).
Linear regression equation showed the significant R2 between the Zn fractions (Total, bound to carbonate, organically organically, bound to manganese (Mn) and iron (fe) oxide with studied soil properties in soils of Homs Governorate.
