For this purpose, a regression model linking <i>R</i>_soil with the level of bog water was constructed. Cumulative soil respiration (<i>R</i>_soil(cum)) was measured in June–August 2021 and 2022. In the dry summer of 2022, <i>R</i>_soil(cum) values increased from waterlogged (hollow E) to better drained (tall ryam and ryam) biotopes and comprised 135 ± 2.3, 139 ± 2.4, 275 ± 7.8, 279 ± 7.5, 466 ± 16.4, 510 ± 18.5 g C/(m² season) for the considered sequence, respectively (mean ± standard deviation).

The <i>R</i>_soil(cum) values in summer 2022 were 29 to 54% higher than those in the same period in 2021.

A series of modelling experiments on pyrogenic fumigation of soil has been carried out to assess the effects of gaseous products of wildfires on soil biochemical parameters. The effects of continuous exposure to gaseous substances and periodical, repetitive effects of smoke exposure on soil have been determined. The results have been compared with a single intense smoke exposure. It was found that pyrogenic impact significantly affected the enzymatic activity of ordinary chernozem. The degree of influence depended on the duration and periodicity of smoke exposure. In all experiments, enzymes of oxidoreductase class (catalase, peroxidase, polyphenol oxidase) were more sensitive to fumigation than invertase from hydrolase class. High concentrations of toxic gases were the cause of suppressed enzymatic activity of soils. The following concentrations exceeded the maximum permissible concentrations for atmospheric air: CO 714 times, phenol (hydroxybenzene) 441 times, acetaldehyde 24100 times, formaldehyde 190 times. Accumulation of polycyclic aromatic hydrocarbons (PAHs) in soil after fumigation was revealed, the total content of PAHs was 377 ng/g. The highest values were recorded for naphthalene, where the concentration was 4.4 times higher than the maximum permissible concentration and phenanthrene, 2.8 times higher than the maximum permissible concentration. It has been found that 60-min intensive smoke affects the soil to a lesser extent than continuous and periodical ones. Indices of enzymatic activity of chernozem after such fumigation decreased by 15–33% depending on the enzyme, and after continuous and periodical by 41–84 and 31–78%, respectively.

A total of 394 Ferralsols soil samples were gathered from navel orange orchards located in the province of Jiangxi, China. To enhance the spectrum information, the spectra were preprocessed using five different techniques, including lg(1/<i>R</i>), multiplicative scatter correction, standard normal variate), detrending and Savitzky-Golay smoothing. Four variable selection algorithms—competitive adaptive reweighted sampling, successive projections algorithm, random frog, and genetic algorithm – were combined with three multivariate methods—partial least squares regression, multiple linear regression, and least squares support vector machine. The most efficient strategy combines LSSVM calibration methods with GA and lg(1/<i>R</i>) preprocessing. It generates values for the determination coefficient of prediction, root mean square error of prediction, and residual predictive deviation that are as follows: 0.8948, 0.1597, and 3.0949, respectively, for SOM; and 0.9129, 0.0021, and 3.4014, respectively, for TN.

In this study, the abandoned salinized cotton fields that had been reclaimed for 1, 3, 5, and 7 years were selected to study the temporal dynamics of soil microbial functional genes through metagenomic technology. The abundance of genes involved in C, N, P, and S cycles increased significantly since the reclamation, among them, the abundance of KEGG Pathway genes and Enzymes after the reclamation increased by 29.10 and 30.20%, respectively compared with those of the CK (abandoned salinized farmland). The Shannon index of KEGG Pathway and Enzyme-annotated genes after the reclamation increased by 0.82 and 1.10%, respectively compared with those of the CK. The permutational multivariate analysis of variance (PERMANOVA) and correlation analysis showed that the decrease in soil Na⁺ content and the increase in soil C/N ratio induced by the reclamation increased the abundance and diversity of soil microbial functional genes. After the reclamation, continuous straw incorporation and fertigation increased the soil C/N ratio, and reduced salinity, thus improving soil quality and soil microbial ecological functions.

Scanning electron microscopy and hydrostatic release tests were used to evaluate the microstructure and controlled-release properties of different urea. Using zero nitrogen treatment and conventional urea treatment as controls, six self-made coated urea were used for different fertilization treatments, with a total of eight treatments set up for ammonia volatilization test and field experiment to study the effects of different fertilization treatments on ammonia volatilization, soil nitrogen supply capacity, wheat yield, and nitrogen use efficiency. The results showed that the RPHDU coating had a complete and tight membrane shell. RPHDU had controlled-release periods for nitrogen, hydroquinone, and dicyandiamide (cumulative nutrient release &gt; 80%) of 112, 56, and 28 days, respectively, effectively controlling the release of nutrients and inhibitors. The treatments of adding inhibitors delayed the ammonia volatilization peak and reduced the peak value, with the RPHDU treatment having the lowest cumulative ammonia volatilization. During the critical growth period of wheat, the soil available nitrogen content in the RPHDU treatment was higher than in other treatments, which brought soil nutrient supply closer to wheat demand. Moreover, the soil apparent nitrification rate was lower in the RPHDU treatment than in other treatments throughout the entire wheat growth cycle, reducing the risk of nitrate nitrogen leaching. The RPHDU treatment achieved the highest wheat yield and nitrogen use efficiency, which were significantly increased by 21 and 21%, respectively, compared to the U treatment. In summary, RPHDU could more effectively control nutrient release, improve soil nitrogen supply capacity, reduce soil nitrogen loss, and increase wheat yield and nitrogen use efficiency.

Therefore, the decomposition of litter and roots as one of the key processes in the carbon cycle in the soils of northern forests proceeds almost everywhere in the presence of charcoal. To date, the data on the influence of charcoal on the organic material decomposition in boreal forests are extremely scarce and most of them do not consider the cold period, which lasts on the average half a year in this zone. The goal of this work is to determine the seasonal influence of charcoal on the decomposition of plant litter of different qualities (larch needles, birch leaves, grasses, and mixtures of these litter types) on the soil surface and the roots of the same types in the soil. A field litterbag experiment demonstrates that charcoal accelerates the decomposition of litter in a species-specific manner. Charcoal accelerates the mass loss of recalcitrant aboveground litter (needles) and all types of roots during the cold season. As for the warm season, charcoal accelerates the decomposition of only needles and has no effect on the roots. Thus, our study shows a greater influence of charcoal on the subsoil decomposition especially in the cold season. The seasonal influence of charcoal is demonstrated for the first time and should be taken into account as an important factor of humus formation and carbon dynamics in the soils of boreal forests.</p>","PeriodicalId":11892,"journal":{"name":"Eurasian Soil Science","volume":"56 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140147941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
