“…Furthermore, in the dry season, concentrations of TP, MBC and Bic-P o were significantly higher in NP than RP treatments (Tables 1 and 2). A similar result was obtained by Hou, et al [54], who believed that the increase in soil AcPME activity may be a combined result of the higher MBC and the easily mineralizable labile P o . Bhandari, et al [20] also found that the higher enzyme activities including P mineralization was associated with higher levels of SOC, TN, MBC, and MBN.…”

Soil phosphorus (P) is one of the essential macronutrients for plant growth. Phosphatase-mediated P mineralization in particular is critical for the biogeochemical cycling of P, and its activity reflects the organic P (Po) mineralization potential in soils. In recent years, global climate change has led to changes in precipitation, which inevitably has affected the P cycle as well. To study these effects of precipitation on soil acid phosphomonoesterase (AcPME) activity, the following combined thinning and precipitation treatments were conducted across Larix principis-rupprechtii Mayr. plantations in China: control (CK), light (LT), moderate (MT), and high thinning (HT). The precipitation treatments included natural precipitation (NP), 30% reduced precipitation (RP30), and 60% reduced precipitation (RP60). Soil moisture, microbial biomass carbon (MBC), and soil P fractions were also determined to link their effects on soil AcPME. The results show that soil AcPME activity was significantly higher in the rainy season, which is associated with higher microbial activity and increased P demand, than in the dry season. Generally, soil AcPME activity was found to increase with thinning intensity. In the dry season, the NP treatment was more conducive to improving soil AcPME activity. In the rainy season, the RP60 treatment inhibited soil AcPME activity under all thinning treatments. The RP30 treatment was only found to offer a significant boost for MT. These results indicate that the potential transformation rate of Po may be more dependent on water in the dry season than in the rainy season. If drought occurs, the Po mineralization rate would decrease for all L. principis-rupprechtii plantations, but excessive rainfall in the rainy season would also impact the turnover of Po into MT adversely.

“…4), which is consistent with studies conducted in old-field ecosystems in North America and a tropical low-flooding forest in Mexico, but inconsistent with the results of grass pot culture experiments (van der Heijden et al, 1998;Koch et al, 2012;Solis-Rodriguez et al, 2020). In addition, the OF was proven as N-rich (Lu et al, 2014) and P-limited (Huang et al, 2013;Hou et al, 2015) forest, plants and AMF may form strong mutualism according to Johnson's trade balance model (Johnson, 2010). Previous study on carbon allocation found greater portion of NPP allocated to belowground in the OF than in the YF (Tang et al, 2011), higher plant C supply in the OF also suggested higher AMF demand (Johnson 2010), which may result in higher AMF diversity in the OF compared with the YF.…”

Altitude is a determining factor of ecosystem properties and processes in mountains. This study investigated the changes in the concentrations of carbon (C), nitrogen (N), and phosphorus (P) and their ratios in four key ecosystem components (forest floor litter, fine roots, soil, and soil microorganisms) along an altitudinal gradient (from 50 m to 950 m a.s.l.) in subtropical China. The results showed that soil organic C and microbial biomass C concentrations increased linearly with increasing altitude. Similar trends were observed for concentrations of total soil N and microbial biomass N. In contrast, the N concentration of litter and fine roots decreased linearly with altitude. With increasing altitude, litter, fine roots, and soil C:N ratios increased linearly, while the C:N ratio of soil microbial biomass did not change significantly. Phosphorus concentration and C:P and N:P ratios of all ecosystem components generally had nonlinear relationships with altitude. Our results indicate that the altitudinal pattern of plant and soil nutrient status differs among ecosystem components and that the relative importance of P vs. N limitation for ecosystem functions and processes shifts along altitudinal gradients.
