Implementing management practices that enhance nature-based processes (NBS) is crucial for reversing this trend. Developing simple yet sensitive indicators to assess the impact of these practices on soil quality is essential for evaluating progress toward sustainability goals. In this study, 31 soil health indicators were assessed across 12 olive groves implementing NBS, 12 conventional groves without NBS, and two forest ecosystems. An agroecological sustainability index (ASI) was used to score management practices. Compared to conventional groves, NBS-managed soils exhibited 52–285 % higher levels of soil organic carbon, total nitrogen, and microbiological activity, all of which were significantly correlated with ASI scores. Soil functional α-diversity was also significantly higher in NBS groves and comparable to or exceeding that of forest soils. A minimum data set of eight indicators was identified to establish a soil health index, with effectively detected variations in NBS implementation intensity, showing a significant correlation with ASI (r = 0.76). Overall, NBS adoption led to a 72 % recovery of soil health in olive groves. Given that the ASI relies on qualitative, easily accessible information for farmers and strongly correlates with the soil health index, it could serve as a practical tool for predicting NBS impacts and supporting the European Uniońs sustainability objectives.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"457 ","pages":"Article 117276"},"PeriodicalIF":5.6,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143785769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes, in turn, may hamper soil aeration, restrict gas exchange, and therefore, cause establishment of anoxic conditions in upland soils. Such periodic fluctuations of aeration control the activity of microbial extracellular hydrolytic enzymes. Earlier studies revealed a clear suppression of key hydrolytic enzymes due to a short-term aeration (i.e., oxygen exposure) of established anoxic ecosystems such as rice paddies. However, it remains unclear whether the suppression also occurs in upland soils with periodic anoxicity. This key gap was addressed by measuring the kinetic parameters and <em>in situ</em> activities of hydrolytic β-glucosidases and acid phosphatases under oxic and anoxic conditions in forest, grassland, and cropland mineral soil after 3–5 days of anoxic pre-incubation. Short-term (2 h) aeration suppressed β-glucosidase and acid phosphatase activities by up to two times as compared with activities under anoxic conditions. The suppressive effects of aeration on the maximum reaction rate of enzymatic activity (V_max) were more pronounced in the cropland (by 1.6–2.4 times) than in the forest (by 1.3–1.7 times) soil. Our findings indicate the importance of fluctuations in redox conditions in the soil organic matter transformation catalyzed by hydrolytic enzymes, particularly in scenarios where the frequency and/or severity of flooding events increase due to changes in land use and/or climatic conditions. The mechanism of the suppression of hydrolytic enzyme activities has been demonstrated to be sustainable in lowland and upland ecosystems, yet further studies are required to elucidate the biogeochemical basis for this phenomenon.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"457 ","pages":"Article 117278"},"PeriodicalIF":5.6,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disease-suppressive soils are an effective and sustainable resource for managing soilborne diseases in monoculture systems. However, the evolution and mechanisms of soil suppressiveness remain elusive, limiting the broader acceptance of suppressive soil in agriculture. This study investigated changes in the belowground tomato microbiome during long-term monoculture leading to an outbreak and subsequent suppression of bacterial wilt, a destructive soilborne disease. The wilt incidence steadily increased, culminating in the most severe outbreak in the fifth cropping cycle. Surprisingly, in the seventh crop, wilt symptoms spontaneously declined, signifying a transition toward the disease-suppressive state. This transition involved the enrichment of <em>Streptomyces</em> and trace elements (Mn, Ni) in the bulk soil, accompanied by increased diversity and abundance of <em>Pseudomonas</em> in the rhizosphere<em>.</em> Greenhouse disease assays confirmed that the suppressive soil had significantly lower wilt incidence and shaped a healthy rhizosphere community characterized by reduced prevalence of pathogenic taxa and greater resource utilization diversity, compared to its disease-conducive counterpart. Moreover, functional analysis of the suppressive rhizosphere metagenome revealed enrichment of genes for the synthesis of antibiotics, polysaccharides, nitrogen metabolism, mineral absorption, and energy production. Drenching tomato seedlings with suppressive rhizosphere soil suspensions enriched beneficial rhizosphere microorganisms such as <em>Pseudomonas</em> and <em>Bacillus</em>, improving plant growth and physiological characteristics compared to seedlings treated with conducive rhizosphere soil suspensions. Furthermore, <em>Pseudomonas</em> and <em>Bacillus</em> were isolated and validated for their antagonistic ability against <em>R. solanacearum</em>, demonstrating their inhibitory effect on bacterial wilt in greenhouse trials.

We used about 1000 LASTs and 15,000 HFSTs over an area of about 6,800 km². We incorporated the uncertainties of HFST and LAST calibration data in DSM and compared it with a case where measurement errors were ignored. We added progressively HFST calibration data to LAST data and ran predictions and k-fold validations keeping the same validation set for all experiments. We added HFSTs according to different strategies: either based on the most uncertain predicted areas from the LAST-only model, or those from the preceding LAST + nHFST model, or randomly. We discuss the pros and cons of these different strategies. Adding HFST data brought useful information for model calibration, but only if the uncertainty was accounted for. Various strategies for adding HFSTs led to different unbalanced samplings, maps and prediction intervals. We explain how these various unbalanced samplings sharpened or enlarged the predictive distribution of various clay content ranges. Adding a too large number of HFSTs led to an over-optimistic estimation of the 90 % prediction interval and to large homogeneous patterns, smoothing the spatial variation of clay content. Adding HFSTs using weights to acknowledge their uncertainty substantially improved DSM predictions, but the number of HFSTs and the strategy to add them must be carefully adapted.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":"456 ","pages":"Article 117277"},"PeriodicalIF":5.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the kinetics and dynamics of DON, including underlying microbial mechanisms, in the soil profile of an irrigated Merlot vineyard in the Okanagan Valley, BC, Canada. Biennial treatments from 2011 to 2018 included wood-based mulch with or without agricultural compost (26.7 and 13.7 Mg ha⁻¹ fresh weight, respectively) and a non-amended control. In the Fall of 2018, composite soil samples were collected at 15 cm intervals down to 60 cm depth. Microbial N cycling functional potential was determined, and initial DON concentrations, and potentially releasable DON (N₀-_DON), and the DON release rate constant (k-_DON) were assessed via 100-day aerobic incubation. Pre-incubation DON levels (0.89–44.1 mg N kg⁻¹) were higher in mulch + compost ≥ mulch &gt; control and decreased with depth. DON release followed first-order kinetics, with N₀-_DON ranging from 12.1 to 188 mg N kg⁻¹ and being unaffected by amendments, but decreased with depth. Cumulative DON averaged 33.8 mg N kg⁻¹ and was also unaffected by amendments, but it decreased with depth. The k-_DON (0.016–0.224 wk⁻¹) was influenced by amendments and depth, with higher values in mulch + compost compared to mulch-only and control, and it declined with depth. Organic amendments doubled bacterial proteolytic capacity, positively correlating with N parameters. Bacillota-related proteolytic (<em>npr</em>) and nitrate reduction (<em>nrfA</em>) genes were associated with cumulative DON and nitrate release during the incubation, suggesting that mineral N released by proteolytic activity was re-immobilized into microbial biomass, maintaining plant-available N throughout the soil profile. First-order kinetics further support the key role of soil organisms in DON dynamics. In low-N systems like vineyards, DON supply rivals mineral N and increases with organic amendments. While DON supplementation supports mineral N supply, its potential capacity diminishes over the long term, necessitating periodic applications to maintain effectiveness. The relatively fast release of N_min and DON from mulch + compost makes it ideal for early spring applications to synchronize N release with grapevine N uptake.

The relationships between number of aliquots and estimated SOCS variance was determined. Sampling at fixed depth and layer bulk density resulted in unacceptable errors and MDCs exceeding several decades when converted to years before a change was detectable. We introduced a new procedure to fully consider the coarse fraction volume in the layer, which remains a major source of error on the <em>SOCS</em> when the coarse fraction volume exceeds 10 % of the layer volume, while not impacting the detectability of the change. The single-layer ESM method provided an <em>MDC</em> corresponding to less than 10 years before <em>SOCS</em> change detectability under the average regional conditions, and mass correction results in negligible increase in <em>MDC</em> compared to that of the 0–30 cm layer.
