The toxicity tests were conducted using plant bioassays with cress (\u0000 <i>Lepidium sativum</i>\u0000 ), mustard (<i>Sinapis</i>) and sorghum (<i>Sorghum</i>) seeds. The research material consisted of ash (<i>n</i> = 15) obtained from the combustion of: (<i>i</i>) conventional or alternative fuels (i.e., hard coal, wood: pine, birch, spruce, and wood pellets), (<i>ii</i>) mixed fuels (hard coal mixed with wood—different types), and (<i>iii</i>) mixes of conventional fuels and selected fractions of municipal waste (i.e., paper, plastics, textiles). The research method involved measuring the length of the root and shoot sections of the plants after their exposure (24, 48, 72, 96, 120, 144, and 168 h of growth) to a given type of ash, followed by calculating the growth inhibition index (<i>I</i>). The phytotoxic effect appeared as inhibited growth and development of both roots and shoots. The measurements showed that ash produced from combusting pure coal and mixed municipal waste created the most toxic conditions for germinating seeds (<i>I</i> ≅ 90%–98%). Ash from wood pellets was the only material that exhibited the least harmful effects on the test organisms (<i>I</i> &lt; 50%). The study showed that ash from household furnaces exhibits toxic properties and does not provide a suitable environment for plant development. The toxic character of the ash is determined by its chemical composition, which is influenced by: the type and composition of the raw materials used as fuels, the technologies applied in thermal decomposition systems, and the combustion parameters in heating boilers.</p>","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"37 16","pages":"11730-11743"},"PeriodicalIF":4.0,"publicationDate":"2026-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ldr.70840","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148836262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined alpine steppe ecosystems in northern Tibet with a space-for-time substitution approach to analyze dynamic changes in plant productivity and soil aggregate nutrients across different exclusion durations (0, 2, 6, 13, and 18 years). Community aboveground biomass and <i>Stipa purpurea</i> biomass initially increased and peaked after 6 years of exclusion, followed by a gradual decline. In contrast, long-term exclusion (≥ 13 years) significantly increased the proportion of soil macroaggregates and their associated organic carbon, nitrate nitrogen, and available phosphorus contents. Spearman correlation analysis revealed that nitrate nitrogen stored in macroaggregates was negatively correlated with plant productivity. These results indicate an asynchronous response between vegetation recovery and soil aggregate nutrient dynamics during ecological restoration. Plant productivity recovered rapidly in the short term but did not synchronize with improvements in soil structure and nutrient pools. Although prolonged enclosure enhanced total soil nutrient stocks, nutrients became increasingly physically protected within stable macroaggregates, reducing their accessibility to plant roots.

We treat the internal composition of the informal-institutional configuration as a set-theoretic analytical unit, not as a new institution or a standalone causal mechanism and examine how its components combine. Using fuzzy-set Qualitative Comparative Analysis (fsQCA) of 50 community-level cases drawn from a PRISMA-screened Web of Science and Scopus search and triangulated against government, project, and media sources, with two independent coders applying an anchored codebook across four rounds (Cohen's <i>κ</i> = 0.87), we find that three internal conditions and one interplay condition reach the 0.90 near-necessity threshold; collective tenure clarity provides the strongest joint signal (consistency = 0.94; coverage = 0.98).

Failure follows an asymmetric signature in which external intervention is present within a weakened customary substrate.

Vegetation buffer strips (VBS) are widely promoted to reduce erosion and nutrient losses, yet multi-year field evidence for intentionally established native perennial herbaceous VBS under Eastern Mediterranean seasonality remains scarce. We established a large-scale riparian experiment along the Nahalal stream in northern Israel, comparing native perennial herbaceous VBS with conventional wheat cultivation and unmanaged spontaneous annual vegetation. VBS were established through mechanical clearing, surface scraping, soil solarization, sowing, and short-term irrigation. Across five seasonal campaigns over three years, we measured vegetation cover, bare soil, above- and belowground biomass, plant richness, surface-soil organic matter, total nitrogen, nitrate, and Olsen-P. VBS rapidly established and maintained higher cover, lower bare-soil exposure, greater above- and belowground biomass, and higher observed plant richness than both annual treatments. Contrasts were strongest during the autumn dry-to-wet transition, when wheat plots were bare and spontaneous vegetation had largely senesced. VBS also had greater shallow root biomass; a one-time excavation confirmed rooting to 60–70 cm, although these measurements were not directly comparable with repeated shallow sampling. Soil responses were less consistent. Nitrate and Olsen-P differed among treatments during parts of the study, but likely reflected establishment practices, site heterogeneity, and perennial vegetation processes rather than direct evidence of reduced nutrient export. Soil organic matter and total nitrogen changed little during the first three years. This study provides one of the first multi-year field evaluations of intentionally established native perennial herbaceous VBS in an Eastern Mediterranean agroecosystem and identifies the autumn transition as a critical management window.

The Qaidam Basin constitutes a major distribution area of saline-alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt transport mechanism remain poorly constrained. Here, through laboratory physicochemical experiments, we determined the soil electrical conductivity, salt ions, nutrient contents, and particle size distribution in the Gahai profile (GHP) saline-alkali soil (depth: 0–119 cm) of the Qaidam Basin to comprehensively analyze their vertical distribution characteristics. Simultaneously, we employed relevant statistical methods to disclose the relationship between soil nutrients, salt content, and particle size, and to investigate the migration pattern of soil salt ions. The results reveal that the surface soil (0–27 cm) in the GHP profile is severely saline, whereas soil below 27 cm ranges from slightly saline to nonsaline; the entire profile is strongly alkaline. In the surface soil (0–27 cm), the dominant anion is Cl⁻, followed by SO₄\u0000 ²⁻, with Na⁺ as the primary cation. As the soil depth increases, HCO₃\u0000 ⁻ and Ca²⁺ become the main salt ions. The nitrogen and organic matter nutrients are deficient, while phosphorus and potassium have relatively high levels. Soil texture is primarily silty loam and sandy loam. Based on the soil salinity movement pattern, the soil profile could be divided into the salt-ion rising section (0–27 cm) and the equilibrium section (27–119 cm). Accordingly, salt-suppressing irrigation measures can be implemented initially, followed by deep ploughing to bring the lower-layer silt loam soil to the surface. This soil salt transport pattern and control measures may only be applicable to the alluvial-floodplain type of saline-alkali land in extremely arid basins in northwest China, such as those in Qinghai and Xinjiang provinces. These findings enhance our understanding of the distribution characteristics of salts and nutrients in the saline-alkali land of the Qaidam Basin, along with its influencing factors and salt transport mechanisms, offering theoretical support and practical guidance for long-term soil salinization restoration strategies.</p>","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"37 16","pages":"11867-11884"},"PeriodicalIF":4.0,"publicationDate":"2026-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ldr.70865","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148675075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
