[PMID: 39019286 DOI: 10.1016/j.scitotenv.2024.174815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2024] [Revised: 07/13/2024] [Accepted: 07/13/2024] [Indexed: 07/19/2024]
Abstract
Plants are generally limited by soil phosphorus (P) deficiency in forest ecosystems. Soil available P is influenced by lithology, temperature, and soil microbes. However, the interactive effects of these factors on soil P availability in subtropical forests remain unclear. To assess their impacts, we measured soil inorganic and available P fractions and the diversity, composition, and co-occurrence network of phoD-harboring bacteria in two contrasting forest soils (lithosols in karst forests and ferralsols in non-karst forests) in the subtropical regions of southwestern China across six temperature gradients. The present results showed that the complexities in composition and network and the diversity indices of phoD-harboring bacteria were higher in the karst forest soils than those in the non-karst forest soils, with marked differences in composition. In both types of forest soils, the complexities of composition and networks and the diversity indices were higher in the high-temperature regions (mean annual temperature (MAT) > 16 °C) compared to the low-temperature regions (MAT <16 °C). Soil total inorganic and available P contents were lower in the karst forest soils compared to the non-karst forest soils. Soil total available P contents were lower in the high temperature regions than those in the low temperature regions in both forest soils, whereas soil total inorganic P contents were contrary. Variance partitioning analysis showed that soil inorganic and available P fractions were predominantly explained by lithology and its interaction with soil microbes and climate. The present findings demonstrate that soil P availability in subtropical forests of southwestern China is influenced by lithology and temperature, which regulate the diversity, composition, and network connectivity of phoD-harboring bacteria. Furthermore, this study highlights the significance of controlling the composition of phoD-harboring bacteria for mitigating plant P deficiency in karst ecosystems.

Abstract
The phoD-harboring bacterial community is responsible for organic phosphorus (P) mineralization in soil and is important for understanding the interactions between arbuscular mycorrhizal (AM) fungi and phosphate-solubilizing bacteria (PSB) at the community level for organic P turnover. However, current understanding of the phoD-harboring bacterial community associated with AM fungal hyphae responses to organic P levels remains incomplete. Here, two-compartment microcosms were used to explore the response of the phoD-harboring bacterial community in the hyphosphere to organic P levels by high-throughput sequencing. Extraradical hyphae of Funneliformis mosseae enriched the phoD-harboring bacterial community and organic P levels significantly altered the composition of the phoD-harboring bacterial community in the Funneliformis mosseae hyphosphere. The relative abundance of dominant families Pseudomonadaceae and Burkholderiaceae was significantly different among organic P treatments and were positively correlated with alkaline phosphatase activity and available P concentration in the hyphosphere. Furthermore, phytin addition significantly decreased the abundance of the phoD gene, and the latter was significantly and negatively correlated with available P concentration. These findings not only improve the understanding of how organic P influences the phoD-harboring bacterial community but also provide a new insight into AM fungus-PSB interactions at the community level to drive organic P turnover in soil.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 912:169479. [PMID: 38123102 DOI: 10.1016/j.scitotenv.2023.169479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 12/13/2023] [Accepted: 12/16/2023] [Indexed: 12/23/2023]
Abstract
Fertilization is a pervasive approach to agricultural production enhancing vegetable nutrients such as phosphorus (P) absorption. However, unreasonable fertilization strategies result in high levels of residual P in vegetable planting systems. To better understand the mechanisms of soil phosphorus dynamics responding to inorganic/organic fertilization, we conducted a 3-year field experiment in two newly reclaimed vegetable fields in southern China. The results revealed that soil Olsen-P in CF (mineral fertilization) and OF (Combined application of organic and inorganic fertilizers) increased by approximately 210.6 % and 183.6 %, respectively, while stable P proportion decreased by approximately 9.2 % and 18.1 %, respectively, compared with CK. Combined application of organic and inorganic fertilizer increased the proportion of moderately labile P (NaOH-P) by 1-6 % in comparison with chemical fertilizer and facilitated the conversion from diester-P to monoester-P, indicating that applying pig manure enhanced the potential soil P bioavailability. Besides, organic-inorganic fertilization shaped a bacterial community with more connectivity and stability and changed keystone taxa related to the P transformation of the network. Phenylobacterium, Solirubrobacter, and Modestobacter were regarded as core genera for mobilizing soil phosphorus. However, residual P content in newly reclaimed soils under fertilization, especially for chemical fertilizer, remained non-negligible and may cause potential environmental risks. The partial least squares path modeling results demonstrated that fertilization management had both direct and indirect positive effects on P fraction through the improvement of soil nutrients e.g. total N and soil organic carbon, and bacterial community, while soil properties mainly determined the variation of soil P species. Our results provide comprehensive insights into the current status of legacy P forms and the vital role of fertilizer, key soil properties and bacteria in P dynamics in newly reclaimed vegetable field.
