Standing state and cycling of nitrogen in a Garhwal Himalayan grassland under grazing, burning and protection against herbage removal regimes

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

The paper reports the standing state and cycling of nitrogen in 4 regimes viz. once-burnt, twice-burnt, open grazing and protection against herbage removal, in a submontane Garhwal Himalayan grassland. Protection against herbage removal increased average nitrogen content in plant material (shoot+root) over that in burning and open grazing regimes. The soil nitrogen (0–30 cm depth) increased with the frequency of fire. Protection regime had more bearing on the total annual nitrogen uptake by plants than fire and grazing regimes.
