Abstract
The percolation loss of some nitrogenous fertilizers from the tea garden soil was investigated by the lysimeter method.
Greater part of the loss of nitrogen was happened as nitrate form. Among these fertilizers, the rate of loss was the most remarkable in the case of ammonium nitrate, less in urea, ammonium sulphate and the least in calcium cyanamide.
The percolation loss was occurred intensely in summer season, while in winter it diminished.
