“…Soil organic matter decomposition is a fundamental ecosystem process that allows for the cycling of nutrients. The rate of organic matter decomposition is measured using various test objects, such as filter paper [1] , [2] , [3] , [4] , linen [ 5 , 6 ] or cotton [7] , [8] , [9] fabric, tea bags [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , components of woody or herbaceous plants (needles, leaves and branches) [ 11 , [17] , [18] , [19] ]. Recently, the tea bags have become the most widely used among them with the subsequent calculation of a Tea Bag Index (TBI) [ 10 , [20] , [21] , [22] ] proposed by [23] .…”

“…Different species have different nutrient resorption e ciencies due to both biotic (e.g., biological characteristics and leaf traits) and abiotic factors (e.g., climate conditions, soil nutrients) (Brant and Chen 2015; Drenovsky et al 2019; Kobe et al 2005;Lü et al 2015). Leaf traits such as litterfall quality plays an important role in N and P cycling in the forest ecosystems, and litter decomposition directly affects the soil nutrients (Růžek et al 2021;Yang et al 2018). However, the linkage between litter nutrients and nutrient resorption e ciencies are still poor understood (Wang et al 2022b; Zheng et al 2021).…”

Nutrient resorption is an important strategy for obtaining nutrition, it determines the ecosystems productivity and nutrient cycling. The Wuyi rock tea cultivars are used as important species for controlling soil erosion in hilly mountainous areas, but the mechanism of nutrient resorption is still unclear. The Wuyi Rock tea (Camellia sinensis) plantations are the main economic crops in Fujian province, China, and also have important ecological functions. The tea plants can absorb and conserve nutrients from the senesced leaves, but foliar nutrient resorptions of Wuyi Rock tea cultivars have not been well quantified. Three Wuyi Rock tea cultivars (e.g., Wuyi Jingui, Wuyi Rougui, and Wuyi Shuixian) were chosen in the Wuyishan National Soil and Water Conservation & Science and Technology Demonstration Park this study. Resorption efficiencies of nitrogen (NRE), phosphorus (PRE), potassium (KRE) and their stoichiometric characteristics were determined. KRE and NRE of the three tea cultivars were significantly higher than PRE, indicating that P was more limited than N and K. With the exception of Wuyi Rougui, the other two cultivars (Wuyi Jingui and Wuyi Shuixian) had strong stability in the leaf N and P contents under the changing soil environments. Leaf nutrient and leaf traits such as leaf thickness and specific leaf area had significant correlations with nutrient resorption efficiencies, indicating that leaf nutrient and traits can be used as indicators for nutrient resorption status. Wuyi Rock tea cultivars have strong adaptability to the environment, and they also have high carbon sequestration ability. Simultaneously, Wuyi Rock tea cultivars can reabsorb nutrients and be introduced into nutrient poor mountainous areas for soil and water conservation.

“…The Načetín experimental forest stand has been studied since the late 1980s as part of research into the phenomenon of acid rain [19, 20, 21]. Experimental liming by 3 tons per hectare of dolomitic limestone occurred in an experimental plot of Načetín site in 2007, thus “Načetín control” and “Načetín liming” will be used to identify different subplots.…”

Forest growth responds more to air pollution than soil acidification

The forests of central Europe have undergone remarkable transitions in the past 40 years as air quality has improved dramatically. Retrospective analysis of Norway spruce ( Picea abies ) tree rings in the Czech Republic shows that air pollution (e.g. SO 2 concentrations, high acidic deposition to the forest canopy) plays a dominant role in driving forest health. Extensive soil acidification occurred in the highly polluted "Black Triangle" in Central Europe, and upper mineral soils are still acidified. In contrast, acidic atmospheric deposition declined by 80% and atmospheric SO 2 concentration by 90% between the late 1980s and 2010s. Annual tree ring width (TRW) declined in the 1970s and subsequently recovered in the 1990s, tracking SO 2 concentrations closely. Furthermore, recovery of TRW was similar in unlimed and limed stands. Despite large increases in soil base saturation, as well as soil pH, as a result of repeated liming starting in 1981, TRW growth was similar in limed and unlimed plots. TRW recovery was interrupted in 1996 when highly acidic rim (originating from more pronounced decline of alkaline dust than SO 2 from local power plants) injured the spruce canopy, but recovered soon to the pre-episode growth. Across the long-term site history, changes in soil chemistry (pH, base saturation, Bc/Al soil solution ratio) cannot explain observed changes in TRW at the two study sites at which we tracked soil chemistry. Instead, statistically significant recovery in TRW is linked to the trajectory of annual SO 2 concentrations or sulfur deposition at all three stands.
