Straw return is widely acknowledged as a crucial strategy for enhancing soil fertility and increasing crop yields. However, the continuous addition of straw, its slow decomposition, retention can hinder growth. Therefore, it essential to elucidate characteristics straw decomposition. This study aims explore alterations in decomposition rates, well content structure organic components, under combined application swine manure corn broken skin yellow black over time. The findings revealed that rates all treatments increased rapidly early stage, gradually slowed down stabilized later stage. cellulose hemicellulose were generally consistent with those while lignin decomposed more middle stages. Notably, rate components was significantly higher biochar compared other treatments, cellulose, hemicellulose, recorded at: 66.16%, 63.38%, 61.16% 47.96%, respectively, after 360 days. treatment exhibited most substantial damage apparent time, resulted lower C/N ratios pronounced decrease intensity absorption peaks.

As extreme rainfall events become more frequent, leading to increased waterlogging hazards, it is crucial explore various drainage methods that can alleviate the adverse effects of on crop growth, thus addressing challenges related global food security. Field experiments were carried out evaluate impacts different technologies mitigation, rice dry matter accumulation, and yield. The experimental setup included varying straw blind ditch spacings (2, 3, 4, 5 m) subsurface pipe (6, 9, 12 m), with surface serving as control (CK). findings revealed that, in comparison treatments, treatments enhanced volume by 15.1%. Regarding groundwater levels soil moisture, moisture 0–90 cm layer under 11.3% 6.1% lower than those CK well 22.0% 23.9% respectively. Subsurface led significant improvements yield, increasing yield 8.0% 6.0% compared CK. Rice yields initially before decreasing burial spacing reduced.

Straw application (SP) is a promising strategy for the improvement of soil fertility, but biological effects and mechanisms its on microorganisms remain unclear. The investigation into tea plantations (CK/S) in southern Henan, China, without/with straw amendment was carried out to assess SP bacterial communities using high-throughput sequencing. induced community restructuring dominant phyla, e.g., Acidobacteriota, Pseudomonadota, Chloroflexota, with significantly increasing Nitrospirota, Vicinamibacterales Anaerolineaceae (p < 0.05), while reducing Terriglobales 0.05).

Humification of exogenous soil organic matter (ESOM) remodels the compositions and microbial communities soil, thus exerting potential impacts on biogeochemical transformation iron (hydr)oxides associated trace metals. Here, we conducted a 70-day incubation experiment to investigate how aerobic straw humification influenced repartitioning arsenic (As) with ferrihydrite in paddy soil. Results showed that was characterized by rapid OM degradation (1-14 days) subsequent slow maturation (14-70 days). During stage, considerable As (13.1 mg·L-1) released into aqueous phase, which reimmobilized solid phase stage. Meanwhile, low-crystalline structural As/Fe converted more stable species, subtle crystalline transformation. The generated highly unsaturated phenolic compounds enriched Enterobacter Sphingomonas induced (∼3.1%) As(V) reduction, leading release during In carboxylic-rich alicyclic molecules facilitated reimmobilization. Throughout process, organo-mineral complexes formed between via C-O-Fe bond contributed solid-phase stabilization. Collectively, this work highlighted ESOM humification-driven (hydr)oxide redistribution, advancing our understanding coupled behaviors C, Fe,
