Abstract

An investigation was undertaken to study the vertical distribution of DTPA extractable Zn, Fe, Cu and Mn in recent and old flood plains of Ghaggar and Yammuna rivers. The different pedon sites were delineated through visual interpretation of IRS-ID satellite data. The selected pedons representing recent and old flood plains were sampled to enumerate the distribution of available content of Zn, Fe, Cu and Mn. The soils were classified according to Soil Taxonomy. The soils of recent flood plains (Ghaggar and Yammuna) were Typic Undorthents/ Ustorthents and old flood plains (Ghaggar and Yammuna) as Typic Eutrodepts/ Haplustepts. The content of micronutrients (Zn, Fe, Cu and Mn) were found in sufficient amount in all the surface horizons of these pedons. The vertical distribution of all these nutrients was uneven. The physicochemical characteristics of these soils were correlated with micronutrient contents. A significant correlation of these micronutrients (except Zn) was found with organic carbon contents of the soils. Whereas non-significant correlation of these nutrients was observed with Electrical Conductivity, Cation Exchange Capacity, silt and clay content of these soils.

Conclusion

In conclusion, all the micronutrients were found in sufficient amount in surface horizon of all the studied pedon it may be stated that the amounts of DTPA-extractable micronutrients in soils of different areas are significantly related to organic carbon, cation exchange capacity and fine texture. Therefore, organic carbon content alongwith soil texture should be considered when interpreting results for micronutrient availability in soils.
