Abstract

Composting is described as a sustainable alternative to organic waste reuse from the agricultural and household sectors. The organic matter degradation and stabilization product presents great variability due to the waste composition used. Thus, the use of techniques that allow the monitoring of the decomposition process is necessary to determine the quality of the final product. Therefore, this review critically analyzes and updates the chemical spectroscopy methods described for the evaluation of the organic matter transformation in the composting process to optimize and generate amendments for agricultural use. This review examines spectroscopic techniques such as ultraviolet-visible (UV-Vis), infrared (IR), fluorescence, and 13C NMR reported for the evolution and maturation of carbonate structures in composting. In addition, they are used in the study of indicators for monitoring the degradation of complex structures, such as sugars and proteins, for the formation of precursors that are responsible for the formation of highly stabilized substances such as humic and fulvic compounds. Finally, these parameters may be used to elucidate organic matter degradation and its stabilization process, establish patterns that characterize each stage of composting along with its physicochemical characteristics, and monitor potential phytotoxicity levels.

堆肥过程监测的光谱学技术综述

堆肥被描述为农业和家庭部门有机废物再利用的可持续替代方案。由于所使用的废物成分，有机物降解和稳定产品具有很大的可变性。因此，有必要使用允许监测分解过程的技术来确定最终产品的质量。因此，本综述批判性地分析和更新了用于评估堆肥过程中有机物转化的化学光谱方法，以优化和生成农业用途的改良剂。这篇综述考察了光谱技术，如紫外-可见光（UV-Vis）、红外（IR）、荧光和13C NMR，这些技术被报道用于堆肥中碳酸盐结构的演变和成熟。此外，它们还用于研究监测复杂结构（如糖和蛋白质）降解的指标，以形成负责形成高度稳定物质（如腐殖酸和富里酸化合物）的前体。最后，这些参数可用于阐明有机物降解及其稳定过程，建立表征堆肥每个阶段及其物理化学特征的模式，并监测潜在的植物毒性水平。

期刊介绍： Agronomy (ISSN 2073-4395) is an international and cross-disciplinary scholarly journal on agronomy and agroecology. It publishes reviews, regular research papers, communications and short notes, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles.
