Abstract:
The investigation envisaged the study of the loss of nitrogen due to leaching from different nitrogenous fertilizers applied to different types of soil and their comparative efficiency on the performance of rice variety I.R .8. The study has enabled the following conclusions to be drawn. 1. The loss of nitrogen by leaching is not reduced even when nitrogen is applied in the water insoluble form. 2. That the loss of nitrogen through leaching even from the fertilizer containing insoluble form of nitrogen might be due to the reaction between fertilizer and soil solution. 3. The loss of nitrogen depends on the texture of soil receiving nitrogenous fertilizers, maximum loss occurring in sandy soil and minimum in clayey soil. 4. The maximum loss of nitrogen through leaching occurs between 12 and 24 hours after the application of fertilizers.
