The amelioration of subsoil compaction mainly by subsoiling remains a costly and labor-intensive task that necessitates intelligent automation solutions. The aim of this study is to evaluate the effects of drilling vertical hallow cylinders (40 mm in diameter) on subsoil compaction amelioration and fodder maize (<em>Zea mays</em>) yield in a Cambisol, sandy-textured soil over two subsequent cropping seasons. Six treatments with three replicates were tested in plots of 9 m by 9 m area, which were randomly distributed across a field in Flanders, Belgium. These treatments differ in depth (D) and hole-to-hole spacing (S), along with a no drilling control treatment (T0). Treatments consist of T1 (50 cm D by 50 cm S); T2 (50D by 75S); T3 (50D by 100S); T4 (90D by 50S); T5 (90D by 75S); and T6 (90D by 100S). Results showed that while minor improvement in soil compaction and crop yield took place in the first year of drilling after crop harvest, improvements were significant in the second cropping season. The highest yield increases with descending orders were observed in T6 (12.4 %), T5 (7.6 %), T4 (6.8 %) and T3 (1.7 %), compared to T0 treatment. At the second cropping season, BD at 40 cm depth decreased significantly in T3 by 7.5 %, while at 70 cm depth, BD decreased also significantly by 6.2 %, 8.6 %, and 7.4 % in T4, T5, and T6, respectively. These findings suggest that all the treatments with 90 cm depth penetration showed significant decreases in BD and significant increases in yield, with 75 cm and 100 cm spacing providing the highest increases in the yield. Further research is needed to determine the optimal depth and spacing for different crops and soil types.</div></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":"253 ","pages":"Article 106695"},"PeriodicalIF":6.1,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to compare three different integrated livestock systems against a single livestock system under regenerative agriculture practices, investigating how the integrations affect soil structure, emphasizing soil hydraulic properties. The experiment was established in 2012 on clayey soil at the Canguiri Experimental Station, Pinhais municipality, PR, Brazil. The experimental design was a randomized block with three blocks and four treatments: Livestock (L), Crop-Livestock (CL), Livestock-Forest (LF) and Crop-Livestock-Forest (CLF). All systems are managed pesticide-free and according to conservation tillage principles. The samples were collected in 2022, down to 0.30 m. Soil attributes analyzed included saturated hydraulic conductivity (Ks), intrinsic air permeability of soil (Ka) at matric potentials −3 kPa and −10 kPa, soil bulk density (BD), total porosity, porosity of large macropores (MAC; ∅&gt;100 μm), macroporosity (MaP; ∅&gt;30 μm), microporosity (MIC; ∅&lt;30 μm), plant-available water (PAWC), air-filled porosity, organization and connectivity indexes and soil carbon stock (Cst). Integrated systems such as Crop-Livestock (CL) and Crop-Livestock-Forest (CLF) exhibit better soil hydraulic properties compared to Livestock (L). The L and LF systems showed similarities and maintained adequate structural characteristics.

Stable isotope ratios of oxygen and hydrogen in soil water reflect phase changes owing to equilibrium and kinetic effects, which are valuable for examining water-mixing processes in soil. This study aimed to examine the effects of evaporation and condensation of water from soil wrapped in black and white films to quantify the differences in isotope ratio changes between soil columns with and without plastic mulch. A soil-column experiment was conducted to examine the isotopic fluctuation (enrichment) processes of soil water and condensed water using water stable isotopes (δ¹⁸O and δ²H) under the three treatments: black plastic mulching (BPM), white plastic mulching (WPM), and no-mulching (NM). The results showed that plastic mulching significantly reduced net soil evaporation and enhanced soil water storage compared with the NM treatment. The net evaporation ratio (net evaporation to irrigation) decreased more for plastic mulching (BPM: 23.1 %; WPM: 23.7 %) than for bare soil (75.1 %). The isotope ratios of δ¹⁸O and δ²H in soil water were lower in the mulched soil profiles than in bare soil at 0–60 cm depths, suggesting that mulching reduces evaporation because of water retention effect. The vertical profile of isotopic ratios of soil water varied among the three treatments owing to the evaporation effect on the soil surface and the addition of condensation water. Condensate under the plastic mulch exhibited higher (more enriched) δ¹⁸O and δ²H than soil water and source (irrigation) water owing to kinetic isotope fractionation during evaporation. The regression slopes of δ¹⁸O and δ²H decreased more in condensed water than in soil water under the mulching treatments. Therefore, the stable isotope techniques are effective for estimating the ratio of evaporated water that escapes to the atmosphere versus the water that returns to the soil as condensate. In addition, isotopic analysis of condensate reveals the moisture exchange between the topsoil and mulch, particularly vapor exchange obtained using various mulching methods.</div></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":"253 ","pages":"Article 106678"},"PeriodicalIF":6.1,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144194823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is important to optimize the organic material addition by assessing their influence on crop yield and soil quality (<em>SQI</em>) under various environmental and agronomic conditions. This meta-analysis, utilizing 1289 comparisons from 154 publications, evaluated the influence of organic material application on crop yield and <em>SQI</em> under various climates, soils, and agronomic practices (type, application rate, substitution rate of inorganic nitrogen fertilizer, tillage, and rotation) in Northeast China. Results demonstrate that organic material significantly increases crop yield by 14 % and improves <em>SQI</em> by 6 %. For climate, the regions with mean annual temperature &lt; 2 ℃ and annual precipitation of 500–600 mm show optimal effects on crop yield and <em>SQI</em>. For soil conditions, organic material application increases yield by 3 %-10 % and <em>SQI</em> by 9 %–19 % in soils with SOM&lt; 40 g·kg<sup>−1</sup>. In areas with severe soil erosion, organic amendments lead to greater improvement in soil quality by enhancing soil structure, increasing water retention, and promoting plant growth. Agronomic practices, such as crop rotation and longer experimental durations (3–6 years), result in the most significant improvement, while deep plowing has no significant effect. Replacing chemical fertilizers with organic materials improves <em>SQI</em> by 1 %-38 %, but substitution rates above 60 % decline crop yield. An Extreme Gradient Boosting model reveals that the experimental duration and organic material type are primary factors affecting the changes in crop yield and soil quality. Extending the experimental duration can mitigate the negative impacts of high pH or use of single organic fertilizer on crop yield and significantly enhance soil quality in regions with high soil erosion rates. These findings provide valuable insights for optimizing organic amendment strategies to balance yield and soil quality, promoting sustainable agricultural practices.</div></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":"253 ","pages":"Article 106690"},"PeriodicalIF":6.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144195011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
