The established database represents one of the largest and most diverse collections of digestates compositions, with a total of 806 digestates derived from two main collections: (i) 608 digestates from French agricultural anaerobic digestion (AD) plants, which include detailed physicochemical characterization, trace metal elements and organic contaminants concentrations, and potential C and N mineralization during soil incubation in controlled conditions as agronomic indicators, and (ii) 198 digestates collected from an international literature review, with physicochemical characterization and some trace metal elements concentrations. An additional dataset of process metadata was also set-up, including feedstock compositions, operational conditions and post-treatments descriptions. A preliminary description of both collections is provided using descriptive statistics. This dataset can help to better understand the variability in digestates quality based on feedstock compositions, operational conditions and post-treatments, thereby improving their agronomic benefits.
已建立的数据库代表了最大且最多样化的沼渣成分集合之一，共有806种沼渣来自两个主要集合：（i）608种来自法国农业厌氧消化（AD）工厂的沼渣，其中包括详细的物理化学特性、痕量金属元素和有机污染物浓度，以及在可控条件下土壤培养期间作为农艺指标的潜在碳和氮矿化；（ii）198种从国际文献综述中收集的沼渣，包括物理化学特性和一些痕量金属元素浓度。还建立了一个过程元数据的额外数据集，包括原料成分、操作条件和后处理描述。使用描述性统计对这两个集合进行了初步描述。该数据集有助于基于原料成分、操作条件和后处理更好地理解沼渣质量的变异性，从而提高其农艺效益。
