Variability of nitrification potentials in patches of undergrowth vegetation in primary Scots pine stands
We investigated whether the distribution of undergrowth species could explain small-scale spatial variability of nitrate production in primary Scots pine stands. This was done by measuring the nitrification potential, i.e. the accumulation of NO3--N in homogenized samples of the ectorganic layer, in...
