Zinc status of soils in Shahdadpur Sindh Pakistan

Qurban Ali Panhwar, . and Radziah O., . (2008) Zinc status of soils in Shahdadpur Sindh Pakistan. [Proceedings Paper]

A study was conducted to determine the zinc status of soils in Shahdadpur Sindh Pakistan. Soil samples from 50 sites Dehs were taken at the depth of 0-15 and 15-45 cm an were analyzed for zinc content and physico-chemical properties. It revealed that the soil texture of the various sites appeared as heavy to medium. The EC 1:5 ranged from 0:16 to 9.96 dS/m at 0-15 cm and 0.15 to 4.74 dS/m at 15-45 cm depths. Soil pH was higher at 15-45 cm depth with mean pH values of 7.93 and 8.14 at 0-15 and 15-45 cm soil depths respectively.The soils were poor in organic matter content 0.93 in 0-15 cm and 0.68 in 15-45 cm soil depth. The CaC03 content ranged from 10 to 18 and the soils were identified as calcareous. The zinc content of the soil varied from 0.35 to 3.07 mg/kg and 0.23 to 0.86 mg/kg at 0-15 and 15-45 cm soil depths respectively. The categorization of the total 50 soil samples for this element at various depths showed that 34 sites were low 0.9 mg/kg 8 were marginal 0.9-1.5 mg/kg and remaining 8 locations were adequate 1.5 mg/kg in Zn concentration. The correlation coefficient studies for Zn showed significantly negative relationship with pH and non-significant relationship was found With OM and CaC03 The sol1s of Shahdadpur were highly calcareous and the high pH inversely affected the availability of Zn.
