The application of natural zeolites to improve soil quality and functioning has become highly popular, but we still miss information about the long-term effects on the soil due to its application. This study assesses the soil quality index (SQI) of three distinct agricultural soil systems 6-10 years after a single application of natural chabazite zeolite as a soil amendment. These soils exhibit different management practices: intensive arable (cereals), intensive perennial (pear) and organic perennial (olive). In the arable system, a zeolite application dosage of 5, 10 and 15 kg m was tested and compared to unamended soil. In the two perennial systems, an application of 5 kg m was tested against untreated reference sols. A set of 25 soil physical, chemical and biological parameters linked to soil health and quality were analysed at each experimental site. The dataset was investigated through Principal Component Analysis (PCA) to calculate the soil quality index (SQI) using linear scoring. In the arable-cereal field, the SQI doubled (0.3 to ca. 0.6 for all amendments) in chabazite-amended plots; a dose effect was not recognizable. In both perennial fields, the SQI was significantly higher in the chabazite-amended plots (5 kg m) with similar increases as compared to the arable-cereal field. At each site, the indicators selected by the PCA were different, indicating that chabazite addition impacted soil quality differently in each cropping system. Overall, the results highlighted a significant increase in soil quality with chabazite amendment, which confirms its potential for increasing soil health in the long-term.
天然沸石在改善土壤质量和功能方面的应用已变得非常普遍，但我们仍缺乏有关其应用对土壤长期影响的信息。本研究评估了在单次施用天然菱沸石作为土壤改良剂6至10年后，三种不同农业土壤系统的土壤质量指数（SQI）。这些土壤呈现出不同的管理方式：集约耕作（谷物）、集约多年生（梨树）和有机多年生（橄榄树）。在耕作系统中，测试了5、10和15 kg/m的沸石施用量，并与未改良土壤进行比较。在两个多年生系统中，测试了5 kg/m的施用量与未处理的对照土壤。在每个试验地点分析了一组与土壤健康和质量相关的25个土壤物理、化学和生物学参数。通过主成分分析（PCA）对数据集进行研究，以使用线性评分计算土壤质量指数（SQI）。在耕作谷物田中，菱沸石改良地块的SQI翻倍（所有改良剂均从0.3增至约0.6）；未观察到剂量效应。在两个多年生田中，菱沸石改良地块（5 kg/m）的SQI显著更高，与耕作谷物田相比增加幅度相似。在每个地点，PCA选择的指标不同，表明添加菱沸石对每个种植系统的土壤质量影响不同。总体而言，结果突出了菱沸石改良后土壤质量的显著提高，这证实了其在长期提高土壤健康方面的潜力。
