Biological productivity of natural plant communities


, : Biological productivity of natural plant communities. Biologicheskii Zhurnal Armenii 42(7): 684-687

In a trial in Armenia in 1987 on a sloping site with a natural plant community on a moderately eroded chestnut soil given 60 kg/ha each of N, P and K in spring or no fertilizer, kinetics of changes in vegetation and the effects of its heterogeneity on biological and economic yields were studied by cutting plots 50 x 50 cm on 4 dates at 15-d intervals between 15 May and 30 June.
