The soil organic matter (SOM) content and quality are the fundamentals of fertility contribute significantly to carbon sequestration. glomalin is increasingly recognized as an indicator SOM quality. objective this study was evaluate capability contribution easily extractable (EEG), total (TG) content, potential wettability index (PWI) aggregates, water stability aggregates (WSA) instrumental indicators long-term changes. obtained results on EEG, TG, PWI, WSA were compared humic substances fractionation, specifically their relationship in substances, acids, fulvic acids (C HS , C HA FA respectively). We used field experiments (27 years) with a simple crop rotation starting potatoes (site A) or maize B), followed by winter wheat spring barley (on both sites) luvisol type. Fertiliser treatments based application uniform 330 kg N ha -1 per three years. Treatments follows: unfertilised control (Cont), sewage sludge normal triple dose (SS1 SS3, respectively), farmyard manure conventional half mineral nitrogen (F1 F1/2+N1/2, straw fertiliser (N+St), only (N). For evaluation effect, data from sites pooled together. F1 treatment showed best for improving (the highest humification rate, index, TG WSA). Cont show degradation No significant effect EEG observed. influenced F1, SS3 (1965, 1958, 1989 mg respectively) comparison (1443 ). tight (R 2 = 0.298; p <0.001). PWI also treatment.

Long-Term Manuring Enhanced Compositional Stability of Glomalin-Related Soil Proteins through Arbuscular Mycorrhizal Fungi Regulation

Agriculture, Journal Year: 2024, Volume and Issue: 14(9), P. 1510 - 1510

Published: Sept. 3, 2024

Glomalin-related soil proteins (GRSP) play a crucial role in strengthening structure and increasing carbon (C) storage. However, the chemical stability of GRSP related arbuscular mycorrhizal fungi (AMF) community response to fertilization remains unclear. This study investigated C nitrogen (N) contents, three-dimensional fluorescence characteristics GRSP, AMF properties based on field experiment that was subjected 29 years various fertilizations. The included treatments with no fertilizer (CK), (NPK), manure (M), combined NPK (NPKM) treatments. Results showed contained 37–49% 6–9% N, respectively. Compared CK NPK, N proportions significantly increased under M NPKM. Using parallel factor model, four fluorescent components were identified: one fulvic acid-like component (C2), tyrosine-like (C4), two humic (C1, C3). Under NPKM, intensity C2 C4 decreased, while humification index (HIX) relative indicating organic could enhance GRSP. proportion positively associated (SOC), total (TN), available phosphorus (AP), biomass, diversity, negative associations. Structural equation modeling further revealed manure-induced changes pH, SOC, TN, AP biomass thereby altering composition stability. provides valuable insights into compositional traits contributing sustainable management sequestration agroecosystems.
