Transformation of zinc in soil under different phosphorus levels on long term fertiliser experiment


Author(s): Najiya Rinthas K, Moossa PP and Thulasi V

Abstract: A field experiment was conducted at Regional Agricultural Research Station, Pattambi to study fractions of Zn under different P levels in Long Term Fertilizer Experiment (LTFE). The field was laid out in RBD having 12 treatments with four replications which was commenced in 1997 and of which 6 treatments having different P levels was taken for the study. The soil samples were taken after the paddy harvest of kharif 2020 and sequential extraction of Zn (water soluble + extractable, organically bound Zn, amorphous sesquioxide Zn and crystalline sesquioxide Zn) and P (sol-P, Al-P, Fe-P, sesquioxide occluded P and Ca-P) were carried out. The results of fractionation study revealed that continuous use of inorganic fertilisers with organic manures (INM) in T5 (100% NPK + FYM) increased various Zn fractions except amorphous sesquioxide Zn fraction which was highest in the control. In case of P fractions even though the increase in P dose increased different P fractions significantly higher content was observed in 100% NPK+ FYM but Ca-P fraction was more in the lime treated plot.
