Effects of Biodegradable Mulch on Soil Microorganisms
AI summary Read the abstract
This review compares biodegradable and traditional plastic mulching films in agriculture, examining how four types of biodegradable plastics affect soil microbial biomass, respiration, and community structure, and evaluating their potential as sustainable alternatives to conventional films that leave persistent residue pollution.
Revised sentence: Plastic mulching film plays a significant role in modern agricultural production. However, traditional plastic mulching film can result in residual film pollution and associated hazards. In contrast, degradable mulching film offers a fundamental solution to the problem of residual film pollution. This paper describes the classification of degradable plastic films and their effects on soil microorganisms, including four known types of biodegradable plastic films. Furthermore, it clarifies the impact of degradable plastic films on soil microbial biomass, soil respiration intensity, and microbial community structure. To compare the efficiency of agricultural production between degradable and traditional plastic films more intuitively, this study aims to identify both advantages and disadvantages of using degradable plastics for future production.

Biodegradable Plastic Mulch Films: Impacts on Soil Microbial Communities and Ecosystem Functions
AI summary Read the abstract
This review examines how biodegradable plastic mulch films affect soil microbial communities and ecosystem functions compared to conventional polyethylene mulches. Researchers found that while biodegradable films avoid the problem of permanent plastic accumulation, their breakdown products can still alter soil microbiomes and carbon cycling in ways that are not yet fully understood. The study highlights the need for long-term field research to determine whether biodegradable mulches are truly a sustainable alternative for agriculture.
