We aimed to investigate the role of indigenous AMF in reducing nitrogen (N) loss from paddy fields via runoff, leaching, NH<sub>3</sub> volatilization, and N<sub>2</sub>O emission. We conducted a pot experiment employing a mycorrhiza-defective rice mutant (non-mycorrhizal) as the control, grown in soil containing indigenous AMF. The corresponding AMF treatment used the progenitor of this mutant with the same soil. The plants were fertilized with nitrogen, phosphorus and potassium 6 weeks after sowing. The root colonization was 23% in mycorrhizal rice, and no typical AMF structures were observed in the roots of non-mycorrhizal rice. Our findings indicated that the mycorrhizal system exhibited lower N concentrations of runoff and leachate further compounded by reduced fluxes of N<sub>2</sub>O and NH<sub>3</sub>. This led to 14% decrease (mycorrhizal rice 111 kg N ha<sup>−1</sup>; the non-mycorrhizal rice: 129 kg N ha<sup>−1</sup>) in cumulative N loss within 3 days post-fertilization. While this AMF effect was consistent across the four tested N loss pathways, differences were observed between NH<sub>4</sub><sup>+</sup>-N and NO<sub>3</sub><sup>−</sup>-N in the runoff pathway. Notably, our results revealed no evidence of trade-offs in AMF effect on N loss among the tested pathways.

The results showed that most mixed plantations significantly increased pH and citric acid and decreased exchangeable Fe<sup>3+</sup> and Al<sup>3+</sup> and the activation of Fe and Al oxides compared with monospecific plantations, which significantly reduced P precipitation and adsorption. Mixed planting significantly increased phosphatase activity and altered the community composition of P-mobilizing bacteria carrying <i>phoD</i> and <i>pqqC</i> genes, which contributed to organic P mineralization and inorganic P (Pi) desorption. Mixed planting increased microbial biomass and the relative rate of microbial biomass P turnover. Labile organic P (Enzyme-P) was a potentially significant source of soluble Pi (CaCl<sub>2</sub>-P) among the biologically-based P fractions, plus microbial biomass P. Overall, introducing broadleaved species, especially in species (e.g. <i>Cercidiphyllum japonicum</i>, <i>Michelia maudiae</i> and <i>Camellia oleifera</i>) with relatively high litter quality and belowground secretions (e.g. citric acid, phosphatase), significantly increased the solubilization of recalcitrant Pi (HCl-P), desorption of chemisorbed Pi (Citrate-P) and accumulation and mineralization of Enzyme-P, thereby increasing the available P pools.

Management can improve soil properties and thus soil fertility. In European wine-growing regions, a broad range of inter-row management strategies evolved based on specific local site conditions and the varying effects of management intensities on soil, water balance, yield and grape quality. Accordingly, there is a need to investigate the effects of locally common cover crop management strategies and tillage intensity on soil organic carbon content and soil physical parameters. In this study, we investigated the impact of the most common inter-row management practices in Austria, France, Romania and Spain. In all countries, we compared paired sites. Each site with cover crops and inter-row management of low intensity was compared with one site with (temporarily) bare soil and high management intensity. All studied sites with cover crops and low management intensity, except those in Spain, had higher organic carbon contents than the paired more intensively managed vineyards. However, the highly water-limited Spanish vineyards with temporary cover crops had lower organic carbon contents than the paired sites with bare soil. Sites with more organic carbon had better results for bulk density, percolation stability (PS), hydraulic conductivity and available soil water, with soil hydraulic parameters being less pronounced than others. Country comparison of inter-row weed control systems showed that PS was particularly low in sampled vineyards in Romania and Spain, where weed control is based on intensive mechanical tillage. Alternating management systems with tillage every second inter-row showed a decrease in soil structure compared with permanent green cover. Thus, inter-row management with cover crops and reduced tillage increases soil organic carbon content and improves soil structure compared with bare soil management. If local constraints, such as water scarcity, do not allow year-round planting, alternating inter-row management with several years of alternating periods may be an option to mitigate those adverse effects. However, negative impact on the soil structure occurs with the very first tillage operation, whereas negative effects on the carbon balance only appear after long-term use of tillage.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.13573","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142130428","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}

Defining relatively simple, but scientifically sound, indicators and thresholds for ecosystem services can be the basis for a transparent regulatory system justifying payment for ecosystem services provided to society. The current serious lack of trust between the policy and farming arenas can and should be restored by scientists and farmers working jointly in Living Labs, aiming to become Lighthouses, to be part of Communites of Practice (CoP). A Living Lab case study is reviewed showing that much know-how is already available to define indicators and innovative cutting-edge methodology adds attractive new opportunities for rapid and relatively cheap characterizations. Field work remains essential and just routinely applying standard techniques fed by existing databases may lead to poor results. Research on indicator-thresholds has a high priority. In the case study, the important soil fertility indicator was based on the current procedure of field sampling and fertilization recommendations by specialized agencies, that is already followed by 85% of farmers. This could be expanded by including indicators for other ecosystem services thereby contributing substantially to the societal sustainability debate. Soil health plays a key role when contributing to all ecosystem services. Showing this with specific examples in a Living Lab/Lighthouse and CoP context is the best way to promote the profession which is needed to justify current major funding. Not only cutting-edge research can contribute to defining indicators and thresholds. A hundred years of research has produced many valuable insights and methodologies that can be applied as well.

However, their temporal evolution is rarely studied, and even less in the field. Thus, their dynamics are rarely taken into account in models, often leading to inconsistent results and poor decision making. In this study, the temporal evolution of water retention properties and soil structure was monitored over a 3-year period under several contrasting production systems. Soil Water Retention Curves (SWRCs) obtained directly in the field (with soil water content and potential sensors) were compared with theoretical SWRCs predicted by pedotransfer functions (PTFs) and laboratory SWRCs measured on undisturbed samples. Bulk densities were measured every 2 months. Results indicate a high degree of variability in SWRCs over time and between production systems. The results suggest that variations in the soil water retention behaviour can be induced by crop differentiation, weed control, crop residue management, compaction during harvest, or the introduction of temporary grassland. Contrasting climatic conditions between 2021 (water excess), 2022 (severe drought) and 2023 (intermediate) provided a unique opportunity to study the resilience of the crop systems to extreme climatic conditions. Different soil drying dynamics were observed and some agricultural practices were identified as influencing the soil water retention behaviour for at least 2 years. Comparison of SWRCs showed that the theoretical curves obtained from PTFs are not a good representation of the field SWRCs, especially for less conventional agricultural practices. The laboratory curves are closer with similar trends. However, these SWRCs are not optimal for investigating the temporal evolution of water retention properties. This research also shows that agricultural practices and crops can be levers for contributing to greater food resilience against future climatic conditions. Therefore, to assess the relevance of production systems for tomorrow's needs, studies should focus on the impact of multi-cropping systems on water retention dynamics in the field.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142089871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In two crop seasons, long-term N fertilization significantly increased the content and proportion of moderately labile Pi (aluminium- and iron-bound P) and available P (AP) and significantly decreased the proportion of recalcitrant Pi (calcium-bound P) compared with the control. Specifically, AP increased by 79%–778%, Fe-P by 64%–88%, and Al-P by 71%–308%, while Ca-P decreased by 10%–59%. N fertilization increased the relative abundance of <i>Micromonospora</i>, which was significantly positively correlated with moderately labile Pi and AP. Moreover, the relative abundance of some <i>Streptomyces</i> increased by 391% in the sweet potato season, and they were positively correlated with AP. Structural equation modelling revealed that the interplay between the <i>pqqC</i>-harbouring community composition and Pi mobilization was mainly governed by pH, underscoring the role of pH in shaping the communities of Pi-mobilizing microbes and their effect on Pi mobilization processes. This study emphasized how N fertilization and crops reshape Pi-mobilizing microbial communities, which in turn affects Pi mobilization and P availability. Overall, these findings offer valuable insights into optimizing P cycles and availability through N fertilization strategies.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142050508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
