Agricultural mulching is an important input for modern agricultural production and plays role in guaranteeing food security worldwide. At present, polyethylene (PE) still commonly used most countries around the world, which non-biodegradable, years of have caused serious white pollution. Lignin one three major components plant cell walls, it also main renewable natural aromatic compounds nature. Lignin-based composite film materials are green, biodegradable, show good prospects development field mulch. This paper introduces types, structure, application status lignin, summarizes preparation lignin-based its latest research progress, focuses on methods, examples mulching, looks forward to future mulching.

Microbial Ecology, Год журнала: 2024, Номер 87(1)

Опубликована: Июль 31, 2024

Abstract Mulching is a common method increasing crop yield and achieving out-of-season production; nevertheless, their removal poses significant environmental danger. In this scenario, the use of biodegradable plastic mulches comes up as solution to increase sustainability practice, they can be tilled in soil without risk for environment. context, it important study microbial response considering direct involvement biodegradation. This evaluated biodegradation three commercial mulch residues: one conventional non-biodegradable versus two ones (white black compostable Mater-Bi mulches). The experiment was conducted under incubation temperatures (room temperature 20–25 °C, 30 45 °C) 6-month trial using fallow agricultural soil. Soil residues used control. White mater-bi showed higher degradation rates 88.90% at 69.15% room temperature. Furthermore, °C determines absence all types considered. Moreover, bacterial alpha diversity primarily influenced by type temperature, while fungal populations were mainly affected Beta impacted experimental variables. Predicted functional genes crucial degrading complex substrates, including those encoding hydrolases, cutinases, cellobiosidases, lipases, derived from 16S rRNA gene sequencing data. Cluster analysis based on predicted enzyme-encoding abundance revealed clusters, linked sampling time. Finally, core microbiome identified dominant taxa various soil-plastic ecosystems during degradation, pinpointing species potentially involved breakdown. present allows an assessment how different affect soil, providing insights climatic growing zones. It also fills gap literature directly comparing effects polyethylene communities.

Biodegradability Study of Modified Chitosan Films with Cinnamic Acid and Ellagic Acid in Soil

Polymers, Год журнала: 2024, Номер 16(5), С. 574 - 574

Опубликована: Фев. 20, 2024

Currently, natural polymer materials with bactericidal properties are extremely popular. Unfortunately, although the biopolymer material itself is biodegradable, its enrichment compounds may affect efficiency of biodegradation by soil microflora. Therefore, primary objective this study was to evaluate utility fungi belonging genus Trichoderma in facilitating degradation chitosan film modified cinnamic acid and ellagic environment. Only two strains (T.07 T.14) used films as a source carbon nitrogen. However, their respiratory activity decreased addition tested phenolic acids, especially acid. Addition isolates increased oxygen consumption during process compared native microorganisms, after application T.07 T.14 consortium. Isolates showed high lipolytic (55.78 U/h 62.21 U/h) chitinase (43.03 41.27 activities. Chitinase incorporation into higher for samples enriched T.07, The were classified sp. koningii. Considering outcomes derived from our findings, it contention that holds promise expediting containing compounds.

Effects of biodegradable film types and drip irrigation amounts on maize growth and field carbon sequestration in arid northwest China

Agricultural Water Management, Год журнала: 2024, Номер 299, С. 108894 - 108894

Опубликована: Май 23, 2024

Biodegradable film (BF), as a superior substitute for traditional polyethylene (PF), has experienced consistent increase in China. However, significant research gap persists regarding the utilization of BF assessing farmland carbon balance. This experiment examined responses maize growth, yield, irrigation water productivity (IWP), CO2 emissions, and field net sequestration (NCS) to two types (BF1, 100-day induction period, BF2, 80-day period), PF, three amounts (I1, I2, I3: 5250, 5625, 6000 m3 ha–1), by conducting two-year (2019–2020) trial typical arid semi-arid region The results indicated that biodegradable mulching (BFM) negatively affected resulting reduced yield IWP. Especially under I1 level, 6.26%–13.99% IWP 6.64–13.85%. Notably, I2 BF1 had comparable impact on PF. Additionally, exerted more pronounced promoting effect total biomass than Concerning balance, short-term application resulted emissions (5.74–6.30% 9.27–12.37% BF2), without any NCS cropland. Taking into account economic value ecology, we recommended utilizing 5625 ha–1 areas, while opting with longer period whenever feasible.

Evaluating the Impact of Traditional and Biodegradable Mulch Film Residues on Heavy Metal Dynamics and Maize Productivity: Insights from Arbuscular Mycorrhizal Fungi Community Analysis

Agronomy, Год журнала: 2025, Номер 15(4), С. 780 - 780

Опубликована: Март 22, 2025

Microplastics and heavy metals (HMs) in soil pose significant environmental health risks, yet the interactions between mulch film residues HMs, their effects on maize productivity, remain poorly understood. This study examined impacts of long-term traditional polyethylene (TMF) biodegradable (BMF) properties, root accumulation arbuscular mycorrhizal fungi (AMF) community, productivity under open field conditions. TMF significantly increased total carbon (TC), C/N ratio, bioaccumulation coefficients (BACs) arsenic (As) cadmium (Cd) while lowering pH water content. These changes altered AMF colonization enriched Paraglomus genus, leading to enhanced leaf antioxidant activity reduced chlorophyll content, although growth was not statistically affected. In contrast, they improved nutrient availability (e.g., nitrogen phosphorus), TC pH. Notably, BMF decreased BACs As Cd, spore density without altering community structure, ultimately biomass. were associated with BMF’s ability lower chelate thereby mitigating bioavailability promoting plant growth. Furthermore, abundance species, particularly from Claroideoglomus facilitated metal chelation HM plants. The findings underscore potential for co-remediation microplastics highlighting importance mulching strategies sustainable agriculture.

Abstract In this study, a series of biodegradable poly(butylene alkylene carboxylate‐ co ‐terephthalate) copolymers with varying methylene numbers in the units (0, 2, 4, and 8) are synthesized. These copolymers, namely, oxalate‐ (PBOT), succinate‐ (PBST), adipate‐ (PBAT), sebacate‐ (PBSeT), prepared nearly identical structural molar compositions. The objective study is to comprehensively examine impact unit length on barrier properties materials, delving into aspects such as crystallinity, free volume, molecular chain mobility, well adsorption diffusion gases within materials. findings indicate decrease crystallinity from 17.2% for PBOT 10.2% PBSeT increases, while maintaining same chemical composition. Concurrently, fractional volume increases 0.9% 2.6%, melt flow activation energy decreases 106.6 52.1 kJ mol −1 . Importantly, theoretical calculations performed, demonstrating that predominant site gas material's volume. combined observations gradual number groups increases.
