“…In addition, soil TN is an important nutrient element index. The quantity and quality of soil TN directly affect soil characteristics and can reflect the level of soil fertility [23,25,26]. Therefore, an in-depth understanding of the three-dimensional spatial variation characteristics of soil total nitrogen will help to improve the sustainable development of mining land and provide valuable guidance and a basis for land consolidation and precision agriculture in mining areas [27][28][29].…”

Soil nitrogen is very important for crop growth and development. However, the factors affecting the three-dimensional spatial distribution of soil total nitrogen (TN), particularly in coal mining subsidence areas, are unclear. In this study, Markov geostatistics was used to analyse the three-dimensional spatial distribution characteristics and influential factors of TN by examining 180 soil samples from the Zhaogu mine in China. The results showed that the TN content was significantly different at different soil depths (0–20, 20–40, 40–60 cm) and decreased with increasing soil depth. The variation coefficient of the TN content decreased gradually from top to bottom, ranging from 18.18 to 25.62%. In addition, the TN content was greatly affected by mining subsidence, rainfall, irrigation, fertilization and management mode. The factors that influenced the TN content also varied across different slope positions. The TN content of the upslope was the highest, and the TN content of the middle slope was the lowest. These results can provide research ideas and technical countermeasures for ecological environment improvement and sustainable land development in coal mining subsidence areas.

“…Soil C and N dynamics are influenced by climate, soil texture, land‐use patterns, vegetation and ecosystem management (Awasthi et al., 2022; Cai et al., 2016; Dang et al., 2022; Pant et al., 2017). Soils of different fertilities responded positively to N fertilization by increasing soil C and N (Table 3).…”

“…In addition, we estimated microbial turnover based on changes in the soil microbial biomass pool during crop rotation and found that microbial turnover was related to the level of microbial biomass, with little difference in its turnover rate (Tables S3 and S4). (Awasthi et al, 2022;Cai et al, 2016;Dang et al, 2022;Pant et al, 2017). Soils of different fertilities responded positively to N fertilization by increasing soil C and N (Table 3).…”

Soil C and N input drives microbial biomass in paddy–upland rotations. We explored how crop straw return impacts microbial C and N (MBC and MBN) dynamics and their role in rice–oilseed rape rotations at three sites in Hubei Province, China. These sites, under a subtropical monsoon climate, were categorized (using the modified Nemoro equation) as high, moderate and low soil fertility respectively. We found that with straw return, total nitrogen (TN) and soil organic carbon (SOC) increased to the greatest degree in the high fertility soils. Notably, soil MBC and MBN levels varied with soil fertility and were seasonably dependent, being lower in the rice season compared to the oilseed rape season. Structural equation modelling (SEM) revealed diminishing effects of MBC and MBN on soil N accumulation during the oilseed rape season compared to the rice season. In summary, our results highlight the role that microbial biomass can play in C and N accumulation as a soil fertility indicator in paddy–upland rotations.

“…Research has shown that the natural recovery of soil nitrogen is slow, and artificial restoration is required for rapid restoration [ 9 ]. Among them, reclamation in farmland has the advantages of shorter reclamation time and higher economic benefits compared to reclamation in forest land and grassland, which is currently a research hotspot [ 10 , 11 ].…”

Coal mining has caused significant soil nitrogen loss in mining areas, limiting reclamation and reuse in agriculture. This article studies the effects of organic fertilizer, inorganic fertilizer, and the combined application of Pseudomonas fluorescens with the ability of nitrogen fixation on soil nitrogen accumulation and composition in the reclamation area of the Tunlan Coal Mine from 2016 to 2022 under the conditions of equal nitrogen application, providing a scientific basis for microbial fertilization and the rapid increase in nitrogen content in the reclaimed soil of mining areas. The results showed that as the reclamation time increased, the nitrogen content and the composition and structure of the soil treated with fertilization rapidly evolved toward normal farmland soil. The soil nitrogen content increased most rapidly in the presence of added P. fluorescens + organic fertilizer (MB). Compared to other treatments (inorganic fertilizer (CF), organic fertilizer (M), and P. fluorescens + inorganic fertilizer (CFB)), MB increased total nitrogen (TN) to normal farmland soil levels 1–3 years earlier. The comprehensive scores of MB and CFB on the two principal components increased by 1.58 and 0.79 compared to those of M and CF treatments, respectively. This indicates that the combination of P. fluorescens and organic fertilizer improves soil nitrogen accumulation more effectively than the combination of P. fluorescens and inorganic fertilizer. In addition, the application of P. fluorescens increases the content of unknown nitrogen (UN) in acid-hydrolysable nitrogen (AHN) and decreases the content of amino acid nitrogen (AAN) and ammonia nitrogen (AN). However, there was no significant effect on the content of ammonium nitrogen (NH4+-N) and nitrate nitrogen (NO3−-N) in soil-mineralized nitrogen (SMN). When combined with inorganic fertilizer, the contribution of SMN to TN increased by 14.78%, while when combined with organic fertilizer, the contribution of AHN to TN increased by 44.77%. In summary, the use of P. fluorescens is beneficial for nitrogen recovery in the reclaimed soil of coal-mining areas. The optimal fertilization method under the experimental conditions is the combination of P. fluorescens and organic fertilizer.
