TAILIEUCHUNG - Dynamics of zinc in sodic soil with zinc enriched organics

An incubation experiment was conducted at ADAC & RI, Trichy, to study the effect of ZnSO4, chelated Zn and Zn enriched organics on dynamics of Zn in sodic soil at different incubation period. The organics viz., FYM, press mud, poultry manure and vermicompost were enriched (10:1 ratio) with ZnSO4 @ kg ha-1 (recommended dose for hybrid maize). The ZnSO4, chelated Zn and Zn enriched organics were added @ kg ZnSO4 ha-1 . Incubated soil sample were analysed for Zn fractions viz., water soluble + exchangeable Zn (WSEX-Zn), organically bound Zn (OM-Zn), Mn-oxides bound Zn (MNOX-Zn), Zn bound by amorphous sesquioxides (AFeOX-Zn), Zn bound by crystalline sesquioxides (CFeOX-Zn), DTPA Zn and total at different intervals (15, 30 and 45 DAI). Among the various treatments, Zn enriched organics and chelated Zn applied treatments recorded higher water soluble + exchangeable Zn, DTPA-Zn and organically bound Zn when compared to application of ZnSO4 alone. The distribution of different fraction of Zn in soil were significantly influenced by Zn enriched organics and ZnSO4 application and found the in order of WSEX-Zn | International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 01 2019 Journal homepage http Original Research Article https Dynamics of Zinc in Sodic Soil with Zinc Enriched Organics R.

The distribution of different fraction of Zn in soil were significantly influenced by Zn enriched organics and ZnSO4 application and found the in order of WSEX-Zn AFeOX-Zn OM-Zn CFeOX-Zn MNOX-Zn RES-Zn fractions. The higher amount Zn release was observed at Zn enriched organics and commercially chelated Zn application than the application of ZnSO4 alone and control. The release of WSEX OM CFeOX attained peak at 15 DAI and declined thereafter upto 45 DAI whereas the MNOX AFeOX RES and .
