Global Meta-Analysis of Soil Enzyme Responses to Litter Alterations

A meta-analysis synthesizing data from 55 studies on the effects of plant litter addition and removal on soil carbon-degrading enzyme activities and soil respiration. The dataset likely contains aggregated results showing litter addition increased cellulase activity by 25.2% and removal decreased it by 25.9%, while ligninase activity was unaffected. The work was authored by Hao Chen and sourced from the paperswithcode platform.

Use Cases

• Modeling soil respiration dynamics based on changes in cellulase activity.
• Analyzing the temporal decay of litter effects on enzyme activity based on treatment duration.
• Investigating the differential response of microbial decomposition pathways for readily decomposable versus complex carbon pools.

Strengths

• Quantitative synthesis of 55 global studies provides a broad evidence base.
• Reports specific effect sizes, such as a 25.2% increase in cellulase activity with litter addition.
• Examines temporal trends, noting effects on cellulase activity decreased with treatment duration.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data may reflect publication bias inherent to meta-analyses compiled from paperswithcode.
• Last update date is unknown; freshness unverified.
