Dataset from "A variable residue: meta-analysis on the nitrogen fertilizer replacement value of anaerobic digestate"

This dataset contains the data used for the manuscript "A variable residue: meta-analysis on the nitrogen fertilizer replacement value of anaerobic digestate", currently (20-03-2025) under revision for publication.<br>Highlights of the paper:· Global meta-analysis combined 103 paired treatments from 40 field and pot experiments· Anaerobic digestate (AD) and mineral fertilizer were compared at equal N application· N fertilizer replacement value (NFRV) of AD was 0.78 + 0.13 (95% CI)· Large variation was observed in the NFRV of digestate (range -0.54 to 1.97)· A combination of soil and AD characteristics best explained observed variation<br>Here we provide the dataset used for the analysis. Use the README file for additional information about the structure of the dataset, the data collection methodology, and references to publications used in the meta-analysis.

本数据集包含用于手稿《可变残差：厌氧消化液氮肥替代价值的荟萃分析（meta-analysis）》的相关实验数据，该手稿目前（2025年3月20日）处于出版修订阶段。
本研究亮点如下：
· 本次全球荟萃分析整合了来自40项田间与盆栽试验的103组配对处理
· 在同等施氮量条件下，对比了厌氧消化液（anaerobic digestate, AD）与矿物肥料的肥效表现
· 厌氧消化液的氮肥替代价值（nitrogen fertilizer replacement value, NFRV）为0.78 ± 0.13（95%置信区间）
· 观测发现厌氧消化液的氮肥替代价值存在较大波动，取值区间为-0.54至1.97
· 土壤特性与厌氧消化液特征的组合可最佳解释观测到的变异情况
本次提供的数据集即为本次分析所用的全部数据。如需了解数据集结构、数据收集方法，以及本荟萃分析所引用的文献详情，请参阅配套的README文件。
