Natural processes exacerbated by climate change and unsustainable agricultural soil management practices are contributing to the steady decrease in organic C stocks in farmland. Carbon farming practices, underpinned by various incentives, can be used to maintain and increase C stocks in agricultural soils. Carbon credit mechanisms, that is, tradable credits each corresponding to one tonne of CO₂eq, are one such incentive. Carbon credits are issued upon the demonstration of increased soil C stocks over time through the application of C accounting methodologies for each agroecosystem and farming practice. This study presents a detailed and critical analysis of carbon credit methodologies, focusing on agricultural soil C in temperate zones, by comparing the European Commission proposal for a regulation on carbon removals with relevant certification frameworks implemented in extra-European Union industrialized countries (Australia, Alberta in Canada, United States). Based on this, we recommend strengthening the European Commission proposal by (i) expanding the list of eligible agricultural practices, (ii) setting a minimum maintenance time frame for each agricultural practice and incentivizing longer duration, (iii) setting the Good Agricultural and Environmental Conditions of the European Common Agricultural Policy (CAP) as a regulatory baseline, (iv) beyond the regulatory baseline, defining a farm level baseline in terms of carbon farming practices applied that can be monitored through the Integrated Administration and Control System of the CAP, (v) clarifying the interaction between the European Commission proposal of regulation and the CAP, the Soil Monitoring Law, and Land Use/Cover Area Frame Survey inventory, (vi) retaining a portion of unsold carbon credits as a buffer against the risk of reversal and (vii) applying a default discount to account for leakage risk if yield reductions are observed. We propose these recommendations to guarantee effective environmental protection, technical and bureaucratic feasibility as well as economic affordability for farmers.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.13577","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142313332","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}

Zinc (Zn) is an element of particular importance due to its function as a micronutrient for plants including rice and other staple foods. In the current study, our aim was to investigate the effects of salinisation on zinc adsorption onto soils representing at-risk coastal and floodplain environments, addressing in particular our knowledge gap concerning the roles that solution chemistry and soil composition play. To this end, we conducted batch adsorption experiments in the laboratory and ran geochemical models in saline solutions up to 0.7 mol L&lt;sup&gt;−1&lt;/sup&gt; ion strength incorporating both (i) a multi surface model (MSM) for surface reactions containing three phases, that is iron hydroxides, organic matter and phyllosilicate clays, and (ii) aqueous-phase complexation to dissolved organic and inorganic ligands. Surface reactions were modelled using the diffuse double layer model, the NICA–Donnan model and an ion exchange model using the Gaines–Thomas convention. We combined the experimentally determined mass composition of surface phases with generic modelling parameters taken from the literature. We first show that increasing salinity enhances the formation of aqueous Zn-chloride complexes in the presence of dissolved organic matter and bicarbonate, thereby decreasing the availability of free Zn&lt;sup&gt;2+&lt;/sup&gt; and supressing the partitioning of zinc to the adsorbed phase. We demonstrate using batch adsorption experiments with a calcareous hydraquent and a tropaquept, that salinity decreases zinc adsorption strongly in the pH range between 3 and 6. Satisfactory agreement between experiments and model calculations was achieved with root-mean-square errors ranging for different salinities between 2.88% and 2.92% for the hydraquent and between 4.59% and 2.74% for the tropaquept soil. Model predictions of adsorption were slightly inferior at low salinity for the hydraquent soil and at high salinity for the tropaquept soil, pointing possibly to an incomplete geochemical model or to a need to parametrise surface adsorption models at higher ionic strengths. Present surface models have been largely parametrised at lower ionic strength. We lastly apply the MSM to examine zinc adsorption in five endoaquepts soils, representing soil series from Bangladesh. We show that increasing salinity decreases zinc adsorption to the soil organic matter and the clay fractions. We conclude from our findings that increased soil salinity due to rising sea levels and climate change will have a significant impact on zinc cycling and possibly other micronutrients in areas where coastal soils and floodplain soils overlap, such as deltas and estuaries.

The European Commission has proposed a Directive of the European Parliament and of the Council on Soil Monitoring and Resilience (Soil Monitoring Law, SML), the first stage of which is to focus on setting up a soil monitoring framework and assessing soils throughout the EU. Situated in NW Europe, the UK has substantial experience in soil monitoring over the last half century which may usefully contribute to this wider EU effort. A set of overarching principles have and continue to guide design of national soil monitoring and may prove helpful as other European countries embark on similar monitoring programmes. Therefore, we present the principles of design from five decades of national soil monitoring. The monitoring discussed is based on a stratified-random design, has matured in support of policy questions, and operates over space and time scales relevant to the SML. The UK Centre for Ecology &amp; Hydrology (UKCEH) Countryside Surveys (CS) of Great Britain and Northern Ireland, Welsh Government, Environment and Rural Affairs Monitoring and Modelling Programme (ERAMMP) and the England Ecosystem Survey (EES) monitoring programme are national programmes currently operating in the UK. Some important lessons learnt include: adopting a question-based approach; having a clear robust statistical design for the purpose; selecting indicators that address policy and underlying scientific questions; and selecting indicators that can detect change and use robust and well-tested methodologies across a wide range of soil and land use types, remaining valid over long time scales, supporting thinking long-term. Technical lessons learned include the proven cost effectiveness of a stratified-random design including replication, while adopting a common stratification layer of stable environmental attributes aids comparability between monitoring programmes. Common protocols are vital for future intercomparisons, but a full ecosystem approach that includes co-located soil and vegetation samples for interpreting a co-evolving system has proved hugely advantageous. UK monitoring programmes offer a range of experience that may prove valuable to future soil monitoring design to address the major societal challenges of our time, such as maintaining food production and addressing climate change and biodiversity loss.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.13570","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236338","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}

High-throughput quantitative sequencing and phospholipid fatty acids were employed to analyse microbial community properties and biomass, whilst microbial necromass was quantified using biomarker amino sugars. Our results revealed that soil MR kept stable under N deposition. Microorganisms maintained their respiration rates by modifying the characteristics of enzymes rather than altering microbial community properties or biomass. Notably, soil MR increased with latitude across study sites, which was attributed to the restriction of microbial activity by bacterial necromass. Supporting this observation, the recalcitrance of the soil carbon (C) pool to microbial degradation was evidenced to be the stability mechanism underlying the spatial variations in MR. Overall, we propose that MR is resistant to short-term N deposition, whilst it exhibits a pronounced latitude dependence as shaped by the recalcitrant C pool.

Remediation via re-establishment of reducing conditions requires submergence and addition of biodegradable organic carbon (OC) to stimulate activity of reducing bacteria. Addition of straw-derived dissolved organic carbon (DOC) has been shown to induce rapid microbial reduction in sandy sulfuric (pH &lt;4) soils. In clayey sulfuric soil, DOC may be less efficient because of limited availability for microbes due to its sorption to reactive minerals. We tested the possible effect of sorption on the remediative potential of straw-derived DOC using a set of incubation and sorption experiments, and used solid-state ¹³C-NMR spectroscopy for the chemical characterization of OC. The tested materials were a clayey, jarosite-containing sulfuric soil (pH 3), and artificial model soils composed of synthesized jarosite either mixed with quartz powder or quartz powder + clay minerals. The results showed that addition of DOC from wheat straw induces reduction conditions varying with soil sorptivity. For the model soils, DOC sorption was little, and DOC additions of 0.8 mg OC g⁻¹ were sufficient to achieve permanently reducing conditions and an increase in pH to &gt;6.0. In the natural sulfuric soil, much higher DOC additions were needed (1.8 mg OC g⁻¹) to facilitate continuous reducing conditions, but pH increased only to values no higher than 5.0–5.5. The natural soil revealed strong sorption of added DOC. Sorption preferentially reduced the proportion of proteins, while the proportion of lignin components, which can hardly be used by microorganisms under reducing conditions, remained relatively high in solution. Thus, high DOC additions were required to overcome the sorption-induced limitations in OC availability. The results suggest that wheat straw-derived DOC is a promising approach also for remediation of clayey sulfuric soils; however, OC additions need to be adjusted to compensate for possible sorption.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.13574","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142144302","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}
