Abstract
N-mineralisation and inorganic-N uptake in a broad-leafed forest of Central Himalaya. Net N-mineralisation and nitrification rates were measured by in situ incubation of soil in a broad-leafed forest in central Himalaya. The rate of nitrification among different seasons was in the order:rainy more than winter more than summer while that of ammonification was in the order: rainy more than summer more than winter. Rainy season conditions were more favourable for N mineralisation. The size of the available nitrogen pool ranged from 10.0 miu gram per gram (winter) to 35.8 miu gram per gram (March). The trend for N-mineralisation rate was opposite to that of the size of the available N. The value of inorganic-N uptake was maximum in the month of July and ranged between 0 and 25 miu gram per gram across different months. In the present studied forest nitrate-N was the dominant form of inorganic-N taken up by plants. The rate of N-mineralisation was positively correlated with the root decomposition.
