In this study, we evaluated soil health, crop yields, and greenhouse gas (GHG) emissions at a long-term experimental site in Central Europe that comprised two cropping systems: a conventional system with regular tillage, low-diversity crop rotation, and minimal cover cropping, and a conservation system with shallow tillage, diverse crop rotation, and extensive cover cropping. We assessed soil health using 13 physico-chemical and biological parameters, calculated field-scale GHG emissions, and analysed yield dynamics over an eight-year period to evaluate potential crop yield penalties under conservation farming. We observed significant soil health advances (+7%) and reductions in GHG emissions (−43%) with conservation farming, while crop yields for all cultivated crops remained stable. Improvements in soil health were particularly pronounced for nitrogen cycling and microbial-driven processes. For several measured soil health parameters, we found a larger effect of crop species compared to farming system. Further, positive management effects on soil were apparent particularly for winter wheat and to a lesser extent for maize and sugar beet, strongly emphasizing the need for standardized soil health assessments that take crop species into account. Our study demonstrates that easily implementable conservation farming measures such as reduced tillage, increased crop diversity, and enhanced cover cropping can substantially improve soil health and long-term agricultural sustainability without compromising crop yields.

We selectively removed Fe oxides and OC from soil of both poorly aggregated (pure coniferous plantation) and well aggregated (mixed forest) soil systems. The mechanism of particulate organic carbon (POC) and mineral-associated organic carbon (MAOC) sequestration in Fe oxide soil aggregation under broadleaf transformation was studied. The removal of Fe oxides broke the macroaggregates into microaggregates and < silt + clay fractions and revealed the attachment and entanglement effects of plant residues encapsulated by macroaggregates on soil particles, whereas plant residue decomposition maximised the degree of macroaggregate fragmentation (64.8%–100%). These results indicate that POC self-isolates and that the presence of Fe oxides further enhances POC physical occlusion during soil aggregation. The extent of this physical protection provided by Fe oxides follows the order: free Fe (Fe<sub>D</sub>) > amorphous Fe (Fe<sub>O</sub>) > complex Fe (Fe<sub>P</sub>). Specifically, Fe<sub>O</sub> and Fe<sub>P</sub> promote macroaggregate formation through organic–inorganic complexes (MAOC formation) to enhance POC physical occlusion, whereas Fe<sub>D</sub> predominantly forms inorganic–inorganic complexes. Microaggregate formation and MAOC accumulation occurred simultaneously through organic–inorganic interactions with various Fe oxide forms. These processes enhanced soil aggregation and were accompanied by significant accumulation of POC (80.2%–169.8%) and MAOC (41.1%–137.3%) after stand conversion (<i>p</i> < 0.05).

It is therefore important to assess the soil threat level. To do so, scientific indicators have been developed, but their implementation at the country level can be challenging. As stakeholders have good knowledge of soil conditions, stakeholders' perceptions on soil threats could be used as a complementary indicator. The objective of this paper is to explore this possibility focusing on the five soil threats considered by stakeholders as the most important at the European level: erosion, artificialisation, compaction, soil organic carbon (SOC) loss and contamination. A participatory stakeholder consultation conducted in France in 2021 yielded 1444 responses. We elaborated stakeholders' perception maps at the departmental scale, which we compared with scientific indicator maps per soil threat. Our findings indicate that stakeholders consider artificialisation the most important soil threat in France. The spatial distribution of soil threats based on stakeholders' perceptions and scientific indicators matches in 43% of the departments for SOC loss, and in over half of the departments for erosion (50%), compaction (51%), artificialisation (63%) and contamination (74%). The differences can be attributed to higher stakeholders' perception compared to scientific indicators for erosion, SOC loss and contamination. Conversely, for artificialisation and compaction, these differences can be attributed to lower stakeholders' perception than the scientific indicators. Moreover, certain scientific indicators assess the threat only partially, whereas stakeholders may perceive the threat differently or as a whole. When biases in the scientific assessment, stakeholders' perception or comparison are taken into consideration, stakeholders' perceptions can be used as a tool to complement existing scientific indicators.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 5","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://bsssjournals.onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70190","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035374","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}

Laser diffraction method (LDM) has gained popularity because of its speed and reproducibility; however, it remains sensitive to sample preparation and introduction methods. This study evaluated the impact of three manual dosing techniques on PSD results obtained via laser diffraction for seven USDA-classified soil types, with the pipette method used as a reference. Each technique (A: pipetted suspension; B: semiliquid paste; C: dried material) was applied to 1050 measurements. The results revealed a systematic underestimation of clay and overestimation of silt fractions across all LDM techniques, with Technique A yielding the highest relative standard deviation (average RSD for clay: 16.8%; sand: 26.9%). Techniques B and C showed markedly better repeatability (clay RSDs: 7.1% and 10.2%, respectively), with silt exhibiting the highest measurement precision overall (mean RSD: 6.7%). One-way analysis of variance (ANOVA) confirmed that the choice of dosing technique significantly affected the measured clay fraction (<i>p</i> < 0.001), whereas no statistically significant differences were found for silt or sand. All the laser-based techniques misclassified the soil texture in the USDA triangle, with most samples shifting to silt-dominated groups regardless of the true origin. These findings highlight that while LDM itself introduces systematic biases in PSD estimation, the choice of manual dosing technique—particularly uncontrolled suspension pipetting (Technique A)—further amplifies measurement variability, rendering it unsuitable for high-precision applications. These findings highlight the strong influence of manual dosing on LDM outcomes and confirm the unsuitability of uncontrolled suspension pipetting (Technique A) in precision analysis.

Practically however, protected areas are often degraded. In Africa, protected areas are mostly funded through game viewing tourism, where development of the road network to enable game viewing often leads to land degradation. Furthermore, off-road driving is common in such game parks, leading to soil compaction and crusting. Guidelines for sustainable road network development and off-road driving exist but are impossible to apply without a soil map of the game reserve. This paper shows how a digital soil map can be used to create spatial off-road driving guidelines for the Phinda Game Reserve in South Africa. Phinda has a very high road density and therefore an additional aim was to designate roads for closure and rehabilitation, without decreasing the opportunity to view predators. A soil class map with a Kappa value of 0.8 was created using the multinomial logistic regression algorithm and 133 soil observations. A soil sensitivity rating was assigned to each soil class based on the soil properties of the class. The off-driving guideline map showed that off-road driving should be prohibited on 6.7% of the area and can only be practised on 41% of the area when not bare or overgrazed. Using the soil sensitivity map and the locations of accommodation camps and predator sighting hotspots, roads were designated for closure and rehabilitation. In total, 207 km of 17% of roads were designated for closure. These roads were outside of predator hotspot areas and would therefore not negatively affect the touristic experience.
