Soil nitrogen (N), phosphorus (P), potassium (K), and pH are important determinants and indicators of soil fertility and quality. Especially in forest, these soil properties are highly variable in space and time. However, more information on these properties in subtropical forests is needed to improve soil nutrients management and to sustain the productivity of subtropical forests. We collected a total of 838 forest topsoil samples (0–30 cm in depth) based on a 4‐km (E‐W) × 6‐km (S‐N) grid system in subtropical China. Geostatistics (i.e., global and local Moran's I) and geographical information system (GIS) techniques were applied to reveal the spatial distribution of N, P, and K contents and pH in subtropical forest soils. All the measured properties were highly variable. Soil N contents ranged from 9.55 mg kg−1 to 862.40 mg kg−1, P contents from 0.10 mg kg−1 to 195.40 mg kg−1, K contents from 10.00 mg kg−1 to 390.00 mg kg−1, and pH values from 2.69 to 8.09. The soil N, P and K contents correlated positively with soil organic carbon (SOC), while soil pH correlated negatively with SOC (P < 0.05). Global Moran's I revealed that soil N, P, and K contents and pH had significant positive spatial autocorrelations, and clear spatial patterns were identified based on local Moran's I. An exponential model was the best fitted model for soil N, P, K contents and pH. Spatial dependence was moderate for all studied soil variables, indicating that both intrinsic and extrinsic factors played a vital role in spatial heterogeneity. Distribution maps showed that soil N and K had similar spatial distribution patterns: a low value area surrounded by bands of higher values. A large‐scale low content area was observed in the spatial distribution map of soil P. An opposite trend was found for the spatial pattern of soil pH. The spatial distribution maps provide useful information for sustainable forest and environment management in subtropical China.

“…, Huang et al. ). Despite the importance of P in terrestrial ecosystem, very few studies have examined its effects in relation to other abiotic factors, such as water, as well as with the specific identity of the aboveground plant species (e.g., fast‐ and slow‐growing trees, native and exotic trees, and nitrogen and non‐nitrogen‐fixing trees) on soil microbiota under drought stress (Nielsen et al.…”

Influence of phosphorus application and water deficit on the soil microbiota of N₂‐fixing and non‐N‐fixing tree

et al. 2018

Soil water content and phosphorus availability are important factors that are expected to shape soil microbiota. Although the impacts of water deficit (drought) on soil microbiota have been reasonably studied, microbial responses to P addition combined with soil water deficit have rarely been reported, especially in relation to the identity of aboveground tree species. This study was conducted to evaluate the main and interactive effects of drought and P addition on the soil protozoa, microbial communities as determined by phospholipids fatty acids (PLFAs) and enzyme activities in a soil vegetated with N2‐fixing or non‐N‐fixing tree species and in a non‐vegetated soil. The results indicated that the effects of drought, P addition, and their interaction on soil microbiota and chemical properties varied depending on the type of aboveground tree species. Drought significantly decreased the abundance of ciliates, amoebae, total protozoa, and most of the microbial community compared to the optimum water treatment, but the effect was more pronounced under non‐N‐fixers compared to N2‐fixers. P addition significantly increased the nitrate nitrogen (NO3−‐N) and dissolve organic nitrogen (DON) in drought treated soil as compared to the well‐watered counterpart, irrespective of the planting systems. The interaction of P with drought significantly increased the mean abundance of ciliates, flagellates, amoebae, and the total protozoa in soil vegetated with non‐N‐fixers and actinomycetes PLFAs, G+ bacterial PLFAs, and total bacterial PLFAs in the soil vegetated with N2‐fixers. Our finding points to an essential role of P addition and N2‐fixing trees on soil microbiota under drought stress. This study suggests that the effects of P application depend on its interaction with drought and that drought had decreasing effects on the abundance of ciliates, flagellates, amoebae, total protozoa, and the soil microbial communities, but the extent of it effects varied with tree species.
