Revealing the changes in organic carbon (OC) and labile (LOC) fractions soil aggregates is of great significance for better understanding sources sink effects tea plantations. In this study, samples were collected at 0–20 cm depth plantations with different stand ages (including 0 years (nudation), 8 years, 15 23 years) Guangxi, China. Then, divided into sized >2 mm, 2–1 1–0.25 <0.25 mm) by a suitable moisture classification method determination OC LOC fractions. aggregate stability (as indicated mean weight diameter (MWD) geometric (GMD)) was highest cultivation, indicating that these (15-year-old) had stable structure provided physical protection storage. At depth, stocks mainly distributed mm aggregates, regardless ages, implying main carriers During first increased then decreased, reaching levels which critical point from to source after cultivation. Therefore, attention should be paid late (15–23 stage so as maintain effect

Evaluation of Soil Aggregate Sieving: The Impact of Field Moisture Content on Size Distribution and Stability

Agronomy, Journal Year: 2025, Volume and Issue: 15(3), P. 558 - 558

Published: Feb. 25, 2025

Soil aggregation, a critical component of soil structure, is significantly influenced by moisture content, which can vary substantially across different field conditions. The objective this study was to evaluate the impact relative water content (SRWC) on performance and sensitivity aggregate size distribution (DOSA) assessments. We conducted comprehensive analysis range SRWC levels observed consistently high recovery rate sieving (exceeding 99.22%), indicating robust methodology. standard deviation (RSD) DOSA minimal, highlighting precision outcomes, particularly up an 40%. Cluster analysis, based properties, identified six distinct groups, each demonstrating significant correlation between characteristic values SRWC, with determination coefficients (R2) above 0.717. This finding underscores variations in levels. However, fitting curves varied among clusters at same site, exception 5 6 Jinliuhuan Agricultural Sci-Tech Park (JLH), reflecting intricate nature soil–moisture interactions.

Organic matter application on subsoil improves soil organic matter, soil aggregate stability and porosity in coffee plantations

IOP Conference Series Earth and Environmental Science, Journal Year: 2025, Volume and Issue: 1466(1), P. 012004 - 012004

Published: March 1, 2025

Abstract The cultivation of coffee in dry land, especially Sumbermanjing Wetan, faces the challenge low soil organic matter, which affects water availability. Water stress is observed during season, marked by yellowing and shedding leaves, as roots are only active topsoil. Therefore, optimizing root function to reach subsoil essential, one approach being implementation biopore infiltration technology. objectives this research were study impact apllying matters on i) matter content, ii) aggregate quality, iii) porosity. This was conducted a smallholder plantation Argotirto Village, Wetan District. design Randomized Complete Block Design with five treatments: P1 (control/no addition); P2 (biopore hole 40 cm filled goat manure); P3 compost); iv) P4 (compost spread surface); v) P5 (goat manure surface). variables included stability, Organic application carried out 2023 2024. Results indicated that use holes (P2) increased topsoil (0-20 cm) 78.11% (20-60 81.89% second year application. addition whether or compost (P2 P5), improved stability both (the average MWD 4.48 mm, 1.94 mm). Moreover, had highest porosity values 64.7% surface 61.5% subsoil. These findings indicate effective increasing aggregation.

Unveiling the Impact of Organic Fertilizer on Rice (Oryza sativa L.) Salinity Tolerance: Insights from the Integration of NDVI and Metabolomics

Plants, Journal Year: 2025, Volume and Issue: 14(6), P. 902 - 902

Published: March 13, 2025

Soil salinization threatens global agriculture, reducing crop productivity and food security. Developing strategies to improve salt tolerance is crucial for sustainable agriculture. This study examines the role of organic fertilizer in mitigating stress rice (Oryza sativa L.) by integrating NDVI metabolomics. Using salt-sensitive (19X) salt-tolerant (HHZ) cultivars, we aimed (1) evaluate changes metabolite content under stress, (2) assess regulatory effects fertilizer, (3) identify key metabolites involved response fertilizer-induced regulation. Under survival rate 19X plants dropped 6%, while HHZ maintained 38%, with increasing 25% 66% HHZ. values declined sharply (from 0.56 <0.25) but remained stable (~0.56), showing a strong correlation (R2 = 0.87, p < 0.01). provided dynamic, non-destructive assessment health, offering faster more precise evaluation than analysis. Metabolomic analysis identified 12 metabolites, including citric acid, which well recognized regulating tolerance. HTPA, pipecolic maleamic myristoleic acid have previously been reported require further study. Additionally, seven novel metabolites—tridecylic propentofylline, octadeca penten-3-one, 14,16-dihydroxy-benzoxacyclotetradecine-dione, cyclopentadecanolide, HpODE, (±)8,9-DiHETE—were discovered, warranting investigation. Organic alleviated through distinct metabolic mechanisms each cultivar. In 19X, it enhanced antioxidant defenses energy metabolism, oxidative damage improving fatty metabolism. contrast, primarily benefitted from improved membrane stability ion homeostasis, lipid peroxidation stress. These findings support identification screening cultivars also highlighting need cultivar-specific fertilization optimize resilience performance. Based on analysis, 26 out 53 differential were significantly correlated NDVI, confirming association between shifts application. By metabolomics, this provides refined method evaluating responses, capturing early salinity biomarkers. approach may prove valuable application variety screening, precision farming, contributing scientific future improvement agricultural resilience.
