Tree species establish mycorrhizal associations with both ectomycorrhizal (EM) and arbuscular fungi (AM), which play crucial roles in facilitating plant phosphorus (P) acquisition. However, little attention has been given to the effects of EM AM on soil P dynamics underlying mechanisms subtropical forests, where availability is typically low. To address this knowledge gap, we selected two ( Pinus massoniana - PM Castanopsis carlesii CC) Cunninghamia lanceolata Chinese fir, CF Michelia macclurei MM) a common garden established 2012 China. We investigated properties (e.g., pH, organic carbon, total nitrogen, dissolved nitrogen), fractions, phospholipid fatty acids (PLFAs), enzyme activities, foliar manganese (Mn) concentration, nutrients stoichiometry. Our findings revealed that soils hosting had higher levels resin P, NaHCO 3 -Pi, extractable Po, greater percentage Po compared species.

Phosphorous (P) limitation is common not only in tropical rainforest and savanna ecosystems, but also karst forest ecosystems. Soil phoD-harboring microorganisms are essential soil P cycles, very little information available about them A total of 36 samples were collected from two types ecosystems (karst non-karst) over seasons (rainy dry), the diversity community structure measured. The contents (AP), (TP), microbial biomass (MBP) activity alkaline phosphatase (ALP) soils higher than those non-karst soils, whereas CaCl2-P, citrate-P, enzyme-P acid (ACP) opposite. AP content was significantly rainy season dry season, ALP more influenced by forest-type season. network connectivity forests forests. Two dominant orders, Burkholderiales Rhizobiales, keystone taxa these networks forests, their relative abundances microorganic indices (e.g., Shannon–Wiener, Evenness, Richness, Chao1) substantially These positively correlated with SOC TN forests; meanwhile, richness evenness HCl-P, TP Structural equation modelling results showed that abundance mainly pH AP, direct affection pH, activity, indirect through affecting AP. findings highlight cycle regulated it In future, regulating interaction may be critical to alleviating limitations

Due to the influence of Asian southwest monsoon, seasonal drought is serious and water resources are scarce in Yunnan province Southwest China. More effective water-saving irrigation methods should be developed solve problem scarcity dry season. In this study, a subsurface drip method was used improve productivity tomato cultivation. Deficit conducted. We controlled lower limit soil moisture at three different levels (55~65%, 65~75%, 75~85% field capacity). The results indicated that treatment significantly increased height later stage growth. buried pipes, root/shoot ratio 8~18% higher for than surface methods. Though yields using were slightly those obtained methods, quality improved significantly. by 8.5~21.8% chlorophyll content 9.1~17.3%. VC, soluble sugar, solids, sugar acid 6.5~15.2%, 7.3~21.6%, 4.1~6.6%, 3.2~20.8%. This study also optimizing patterns, fruit could more 50%. research will helpful guiding during season monsoon area Asia.

To explore environmental differentiation in the stoichiometric characteristics of carbon (C), nitrogen (N), phosphorus (P), potassium (K), and their ratios among tree species organs different lithological karst regions Guizhou, six common were selected from limestone area Liping dolomite Shibing. The analysis focused on differences contents C, N, P, K, as well C/N, C/P, C/K, N/P, correlations these elements branches, leaves, roots, with aim investigating allocation distribution patterns nutrient under conditions. results showed following: In both regions, exhibited a distinct characteristic: leaves high C levels, but relatively low N P levels. Tree C/K ratios, indicative rapid assimilation rates efficient utilization K. Plant growth region was N-limited, while plant P-limited. However, neither K-limited. adaptation strategies plants result multiple factors, such lithology, organs, interactions elements. conclusion, considering lithology during vegetation restoration management targeted application or fertilizers is expected to promote further enhance sequestration capacity soils.
