RESUMO
The general potential, exchange, and actual (pH) acidities were investigated in the litter of the succession row of swamp birch woods. Their variabilities constitute, respectively, 75.9-174.4, 3.7-25.8 mmol (+)/100 g of the sampling, 3.7-5.5. For the first time, using the methods ofgeostatistics, their spatial variability was analyzed and the contributions of the trend, autocorrelation component, and the radius of the spatial correlation were estimated. It was established that in combination with the tree waste, which is uniformly distributed along the ecological profile, the specific composition of the grass-moss tier, which corresponds to the humidity of edaphon, forms the picture of the spatial structure of acid properties of the litter. It was noted that the prime cause of variability consists in the particularities of the water regime of the habitats of swamp birch woods.
