The present analysis relates to data obtained in the course of annual geobotanical records about the complex pine forest system Pineta sylvestris composita (nemoro-boroherbosa), which started following 45 years of forest reserve regimen observed there and continued for 25 years using a permanent test area in the Prioksko-Terrasnyi Reserve (54.89o N, 37.56о E). Changes in the ecological conditions in the course of successional shifts of plant communities were assessed using the ecological scales of D.N. Tsyganov, G. Ellenberg and E. Landolt. As it is typical of the phytocenosis under study, the process of replacement of the pioneer species of the arboreal tier (Pinus sylvestris L., Betula pendula Roth) by the zonal edificatory species of coniferous-deciduous forests (Picea abies (L.) Karst., Tilia cordata Mill.) was manifested in the naturally determined reduction in the total illumination under tree stand and in a minor increase in soil humidity. The study provides evidence of increased soil fertility, which may be explained with changes in the composition of the tree waste resulting from the increased share of fir trees and lindens in the undergrowth. A complex of factors is responsible for that the grassy and bushy tiers featured increases in the share of stenobiontic species, which are more fastidious with regard to soil fertility. With that, species characteristic for lean habitats were preserved.

“…This is because the exchangeable BCs can not only be absorbed by soil colloids but can also provide exchange sites for H + and alleviate ecosystem damage [ 13 , 16 ]; this is essential for maintaining soil nutrients and buffering soil acidification [ 13 , 17 ]. However, accelerating industrialization and use of N fertilizer has led to increased atmospheric N deposition [ 18 , 19 ], thereby accelerating soil acidification processes [ 1 , 10 ], reducing the capacity of soil exchangeable BCs [ 13 ], decreasing soil buffering capacity [ 20 ], and lowering plant productivity [ 21 , 22 ].…”

Nitrogen (N) is an essential macronutrient for plant function and growth and a key component of amino acids, which form the building blocks of plant proteins and enzymes. However, misuse and overuse of N can have many negative impacts on the ecosystem, such as reducing soil exchangeable base cations (BCs) and causing soil acidification. In this research, we evaluated clonal Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) seedlings grown with exponentially increasing N fertilization (0, 0.5, 1, 2 g N seedling−1) for a 100-day trial in a greenhouse. The growth of seedlings, their nutrient contents, and soil exchangeable cations were measured. We found that N addition significantly increased plant growth and N content but decreased phosphorous (P) and potassium (K) contents in plant seedlings. The high nitrogen (2 g N seedling−1) treated seedlings showed a negative effect on growth, indicating that excessive nitrogen application caused damage to the seedlings. Soil pH, soil exchangeable base cations (BCs), soil total exchangeable bases (TEB), soil cation exchange capacity (CEC), and soil base saturation (BS) significantly decreased following N application. Our results implied that exponential fertilization resulted in soil acidification and degradation of soil capacity for supplying nutrient cations to the soil solution for plant uptake. In addition, the analysis of plants and BCs revealed that Na+ is an important base cation for BCs and for plant growth in nitrogen-induced acidified soils. Our results provide scientific insights for nitrogen application in seedling cultivation in soils and for further studies on the relationship between BCs and plant growth to result in high-quality seedlings while minimizing fertilizer input and mitigating potential soil pollution.
