Effect of simazine, lindane and ceresan on soil respiration and nitrification rates

  • A. C. Gaur

The effect of three pesticidesviz, simazine, lindane and ceresan upto 100-fold of field application was studied on organic matter mineralization as well as on nitrification rates in Delhi alluvial soil. The normal rate of simazine (2 ppm) did not influence CO2 evolution but higher concentrations suppressed it. Lindane and ceresan inhibited CO2 production from soil by normal concentrations but the same CO2 production was enhanced in berseem roots treated soil upto 10 ppm of ceresan.

The nitrification of ammonium sulphate in soil due to these pesticides was impaired significantly for varying periods. The inhibitory effect of higher concentrations was marked only upto 3 weeks, subsequently the rate of nitrification was restored. Among the nitrifiers, Nitrobacter were more susceptible as compared to Nitrosomonas.
