However, little is known about how the placement of acidified biowastes affects biotic and abiotic processes in the soil. Thus, we selected two biowastes: digestate solid fraction (DSF) and meat and bone meal (MBM). Both were applied in their untreated and acidified forms. We hypothesised that the acidification would affect biotic and abiotic processes and, consequently, the P dynamics in the soil. All fertilisers were incubated for 12 days to evaluate abiotic and biotic processes in the placement zone and in the adjacent soil. Assessments included resin-extractable P (resin P) and microbial P contents and δ¹⁸O values at different distances from the placement zone. Microbial respiration was also measured. Acidification significantly increased P release for DSF and MBM. The soil resin P content of acidified biowastes was larger even at greater distances (10–12 mm). For untreated MBM, soil resin P was significantly larger than the negative control up to 4 mm from the placement zone (50–60 mg kg⁻¹). For this treatment, microbial P was relatively increased even at greater distances (150 mg kg⁻¹ at 6–8 mm). Acidification suppressed microbial activity and resulted in lower respiration rates for both MBM and DSF. In addition to that, our results showed a significant correlation between ¹⁸O incorporation into microbial P and microbial respiration. Thus, the greater the microbial activity, the more P is biologically cycled in the microbial biomass. However, no correlation was found between respiration and ¹⁸O incorporation into resin P. These results may indicate an insufficient incubation time for microbes to release P into the soil and/or the co-occurrence of abiotic processes which are not exchanging oxygen between water and phosphate (e.g., desorption). We conclude that for untreated MBM, biotic processes may be the main driver of P movement in the soil. In the case of acidified biowaste, diffusion is the main process moving the P in the soil. This research shows that acidifying biowastes like DSF and MBM boosts P availability through abiotic processes. These findings suggest that acidification can enhance nutrient use efficiency and improve soil fertility. However, further studies are needed to assess the long-term effects on microbial communities and soil health.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481555","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}

Long-term field experiments (LTEs) are valuable to study management effects on soil properties and crop yield. Yet most LTE studies are limited to the topsoil, and farming systems integrating multiple management strategies are often not assessed. This study used three Swedish LTEs to assess the effects of crop rotations and fertilisation on SOC changes. One arable rotation with only annual crops and a ley rotation with annuals, perennial ley and receiving manure were investigated at different application rates of mineral fertilisers. We analysed changes in SOC content and the distribution of SOC content and stocks at multiple soil depths, calculated C inputs and used phospholipid fatty acids (PLFAs) to evaluate how management practices affected SOC in relation to C inputs and microbial communities. Both systems lost carbon in the 0–20 cm topsoil from 1966 to 2019 across sites, but the sandy site lost more than the clayey sites. The ley rotation and nitrogen (N) fertilisation reduced carbon losses. In 2019, SOC stocks in the top 25 cm soil were 3.3 ± 1.6 Mg C ha⁻¹ higher in the ley rotation compared with arable rotation and 2.9 ± 1.6 Mg C ha⁻¹ higher with N fertilisation at the highest rate compared with no N fertilisation. However, the positive effects decreased with depth and became negative at some depths. As a result, differences in SOC stocks to an equivalent depth of 60 cm declined to 0.6 ± 2.4 Mg C ha⁻¹ for rotations and to 1.0 ± 2.4 Mg C ha⁻¹ for N fertilisation. The ley rotation had significantly higher belowground C inputs than the arable rotation, and belowground C inputs were highly associated with changes in SOC. Compared with the arable rotation, total PLFAs, bacterial PLFAs and the ratio of bacteria to fungi in topsoil were significantly higher in the ley rotation, partly attributed to manure application. Our study supports the beneficial effects of leys and manure amendments on SOC compared with systems with only annual crops. It also highlights the risk of losing SOC in the subsoil, especially under mineral N fertilisation. Site characteristics helped to explain the large variation, which must be considered when developing local strategies for SOC accrual in cropland.</p>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ejss.70072","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438753","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}

This research examined how moss crusts affect soil water repellency in these environments using the Water Drop Penetration Time (WDPT) method. The research utilised moss crusts from degraded karst areas with varying levels of degradation, contrasting them with bare soils as controls. Results indicate that degraded subtropical karst soils (calcareous and yellow soils) exhibited no water repellency (WDPT &lt; 5 s). Moss crusts notably enhanced water repellency consistently across various degradation stages, exhibiting slight water repellency (5 s ≤ WDPT &lt; 60 s). Soil water repellency diminished following the removal of moss; however, it remained significantly elevated compared to bare soil. Factors such as soil water content, fine particle content, aggregate stability, organic carbon, total nitrogen, and total potassium were found to significantly influence water repellency. In bare soils, water repellency peaked at 10% water content, weakening thereafter, whereas moss crusts exhibited strongest repellency at 0% water content, diminishing as water content increased. Moreover, both moss crusts and bare soils showed heightened repellency with smaller particle sizes (&lt; 0.05 mm). The hydrological impacts of biocrust-induced water repellency vary, presenting both positive and negative effects that necessitate further investigation.

Beech is seen as a key species for converting spruce-dominated forests to mixed forests, aiming to improve forest resilience. The objective of our study was to examine the long-term effects of a spruce stand and a beech stand that transitioned from a conifer-dominated stand on soil organic carbon (SOC), microbial biomass and the abundance of total bacteria, archaea and fungi. In contrast to most other studies, we used a horizon-based soil sampling approach, which provides better insights into how changes in soil chemical properties influence microbial community composition, and consequently, microbial-based processes like C-sequestration. Composite soil samples from two depths, corresponding to the A horizon (approx. 0–10 cm) and the B horizon (approx. 10–20 cm), representing the entire shallow soil profile, were collected from a European beech (&lt;i&gt;Fagus sylvatica&lt;/i&gt; L.) stand and a Norway spruce (&lt;i&gt;Picea abies&lt;/i&gt; [L.] Karst.) stand sharing the same soil group on limestone and dolomite. In the top A horizon, the spruce stand exhibited significantly higher levels of total organic carbon (C), total nitrogen (N), dissolved organic C and dissolved N compared to the beech stand (11.5% vs. 9.0%; 0.63% vs. 0.52%; 15.3% vs. 9.5 mg C kg&lt;sup&gt;−1&lt;/sup&gt; dry soil; 2.9 vs. 1.6 mg N kg&lt;sup&gt;−1&lt;/sup&gt; dry soil; respectively). The beech stand had significantly higher base saturation (84.6%) in the A horizon compared to the spruce stand (43.6%), primarily due to increased levels of exchangeable Ca&lt;sup&gt;2+&lt;/sup&gt;. The soil pH did not show statistically significant differences between the stands, indicating a strong buffering capacity of the soil and its slow response to changes in the composition of tree species in the stand. Microbial biomass C (MBC) in the A horizon was significantly higher in the spruce than in the beech stand (585 vs. 492 mg C kg&lt;sup&gt;−1&lt;/sup&gt; dry soil, respectively). While the abundance of bacteria and fungi did not differ significantly between the stands, a higher abundance of archaea was observed in the spruce compared to the beech stand. Total SOC stock in the entire soil profile (A and B horizons) was significantly lower in the beech than in the spruce stand (71.20 ± 3.08 t ha&lt;sup&gt;−1&lt;/sup&gt; and 85.35 ± 2.84 t ha&lt;sup&gt;−1&lt;/sup&gt;, respectively), similar to the total MBC stock (0.42 ± 0.01 t ha&lt;sup&gt;−1&lt;/sup&gt; and 0.48 ± 0.02 t ha&lt;sup&gt;−1&lt;/sup&gt;, respectively), with no significant differences observed in the B horizon. In conclusion, 20 years after the transition to a beech stand, significant differences in soil properties compared to spruce stand remain limited and confined to the A horizon. This reflects the gradual nature of changes driven by the litter input. The transition from a conifer-dominated to a beech-dominated stand leads to a reduction in SOC stocks.

The third part proffers potential solutions to tackle soil degradation in Africa. Some of the suggested solutions include afforestation of degraded land, integrated landscape management that involves innovative soil fertility and rangeland management, and effective soil conservation measures to combat erosion. Strengthening policy implementation at regional and country levels, such as awareness creation, education, and community engagement on soils as the basis of human existence, is also crucial. We concluded that no single solution fits all while addressing soil degradation in Africa, but integrated approaches that promote sustainable soil management, such as conservation agriculture, crop rotation, agroforestry, afforestation, organic farming, and community engagement, would have a significant impact in resolving the menace of soil degradation.</p>\u0000 </div>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404353","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}

Based on a long-term P fertilisation experiment in calcareous soil on the Loess Plateau (started in 2014), this study analysed the results of treatments including four P fertilisation rates: 0, 60, 120 and 180 kg P₂O₅ ha⁻¹ (denoted as P0, P60, P120 and P180, respectively). The abundance and community structure of the ALP-encoding gene (<i>phoD</i>) were analysed by PCR amplification and high-throughput sequencing, and the soil P fractions were measured using Hedley sequential fractionation approach. The majority of soil P was present in the form of HCl-Pi, and P fertilisation significantly increased the contents of Resin-P, NaHCO₃-Pi, NaHCO₃-Po, NaOH-Pi, NaOH-Po and HCl-Pi in soil. The ALP activity and <i>phoD</i> gene abundance in the P120 and P180 treatments were significantly less than those in the P0 and P60 treatments: P180 decreased by 14.52% and 46.83% compared with P0, respectively.

All of these classification systems have accommodated AS soils throughout their history and each has demonstrated distinctive changes during particular periods. As our concepts and understanding of AS soils have developed, these have become encoded (quickly or slowly) in our classifications.

In Northwest Europe, prolonged droughts are expected, during which capillary moisture transport may help maintain topsoil moisture. At present, the importance of capillary moisture supply for topsoil moisture during dry summers remains uncertain, and so it is not clear if account thereof during SOC stock simulation is needed. This study aimed to determine whether a ~2-m deep groundwater table supplies moisture to topsoil during a dry summer and its effect on SOC mineralisation in six croplands across common textures (loamy sand, (sandy) loam and silt loam) in Flanders. We adopted a novel approach by installing repacked topsoil columns in situ within the plough layer, with or without a gravel layer below to act as a hydraulic barrier. In the loamy sand and (sandy) loam soils, groundwater tables of up to 2.3-m depth appeared too deep to affect topsoil through capillary moisture transport in our setup since topsoil was even slightly wetter in the gravel treatment, likely due to impeded downward water redistribution following rainfall. This artefact could be avoided with deeper barrier placement. In contrast, in the silt loam fields with groundwater tables up to 2-m depth, soil at a 15-cm depth was significantly wetter (25% volumetric water content (VWC) and a matric suction of −405 cm water height (WH)) when upward water transport was unobstructed compared to when it was blocked by the gravel barrier (18% VWC and −445 cm WH) during a 1-month drought period with very limited rainfall (5.8 mm). Surprisingly, this moisture increase via capillary rise did not enhance C mineralisation. Apparently, in these silt loam soils, C mineralization did not strongly depend on moisture, whereas in the coarser loamy sand soil, temporal moisture fluctuations had a greater impact on C mineralisation. This suggests that if capillary rise were to reach the topsoil, for instance with shallower groundwater, it could potentially influence C mineralisation. However, further research is needed to confirm this effect. Overall, whether groundwater moisture supply significantly impacted topsoil moisture and C mineralisation could only be evaluated in the silt loam croplands. Nonetheless, the proposed hydraulic barrier, with a recommended deeper installation, offers a promising tool for further testing conditions where capillary wetting may influence SOC dynamics.</p>\u0000 </div>","PeriodicalId":12043,"journal":{"name":"European Journal of Soil Science","volume":"76 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143380178","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}
