The structure and soil characteristics of a Pinus tabuliformis planted forest after 60 years of natural development in North China

Near-natural transformation of Pinus tabuliformis better improve soil nutrients and soil microbial community

“…Ascomycota, as a decomposer in soil, is a common fungal community in forest ecosystem and involves in many degradation processes (Riley et al, 2014), supporting the findings of earlier study (Li et al, 2021b). Intriguingly, we found that Subgroup_6, RB41, and Sphingomonas were the dominant bacterial genera, as previously reported in the literature (Shi et al, 2017). Sphingomonas, as one of the abundant microbial groups in soil environment, played a crucial role in the determination of soil nutrient recycling.…”

“…What's more, PTAU, PTVN, and PTRP could increase the soil pH, TC, TN, AN, and AK in different degrees, especially in PTAU. Previous study also showed that the soil pH, TC, TN, and TP concentrations in the P. tabuliformis forest were obviously lower than in a coniferous-broadleaved P. tabuliformis mixed forest (Chen et al, 2017). What's more, the findings from Li et al (2021a) demonstrated that soil pH in the monoculture P. massoniana forest plot existed abundantly lower than that in the broad-leaved tree species plantation.…”
