Mineral soil nitrogen concentration in grass stands after deforestation
1998
Zahora, J. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic))
Ammonium and nitrate concentrations in soil were determined in the initial stage of grass stand formation and in old closed grass stands (Avenella flexuosa, Calamagrostis villosa). Higher concentrations of both ammonium and nitrate ions were found in the 0-10 cm soil layer in comparison with the deeper soil layer of 10-20 cm. The amounts of NO3-N and water-soluble NH4+N generally represented only a small part of total mineral nitrogen in samples just removed. Presented data indicate seasonal fluctuations in ammonium and nitrate concentrations in soil.
