Effect of moisture regimes and pesticides of different biodegradability on transformation of different forms of inorganic and organic N in a dominant soil series of West Bengal
A laboratory experiment was conducted to study the effect of pesticides of different biodegradability on changes in inorganic and organic forms of N in soil maintained under two different moisture regimes. Results revealed that irrespective of pesticides and N treatment, comparatively higher amount of available N is recorded in waterlogged then the soil kept at 60% MHC. Addition of pesticides at lower dose affects the transformation process of organic N in soil. Irrespective of pesticide treatment, in general, hydrolysable NH4 + -N decreased but on the other hand amino acid N increased in soil. Again, the intensity of decrease or increase is more in waterlogged than the soil maintained under 60% of the MHC.
