Fly ash (FA) management is a key concern of ecologists around the world, so its potential as a nutritional supplement for agro-ecosystems needs to be explored. Therefore, alternate techniques that are eco-friendly to manage this emerging dual-edged waste are preferable in this field. The current study sought to determine the soil-modifying, crop yield improvement, and nematicidal properties of FA. In this study, beetroot seeds were sown in pots comprising field soil amended with differing proportions of FA (w/w) revealed the bio-fold properties of FA. Biomineralization and mapping of elements revealed that increased nutritional elements in soil supplemented with 15% FA induced growth-performance and yield of beetroot. Molecularly and morphologically characterized Meloidogyne incognita was used as nematode in this study for optimization of nematicidal properties FA. Plant growth performance, photosynthetic pigments, and yield of beetroot were significantly reduced owing to M. incognita as compared to control (un-treated and un-inoculated), and 15% FA reversed the negative effect of M. incognita significantly (P ) as compared to control plants. Confocal laser microscopy confirmed that 15% FA augmented in soil reduced nematode-juvenile invasion in beetroot as compared with control. The PCA (principal component analysis) accounted for 98.63% and 98.8% for the total-data variability in plants without nematodes and total data variability in treated plants (M. incognita + FA) respectively, which showed fit for a significant correlation between the various studied parameters in present study.
粉煤灰（FA）管理是全世界生态学家关注的一个关键问题，因此需要探索其作为农业生态系统营养补充剂的潜力。因此，在该领域中，首选的是对环境友好的替代技术来管理这种新兴的双刃剑废物。本研究旨在确定 FA 的土壤改良、作物增产和杀线虫特性。在这项研究中，在包含不同比例 FA（w/w）的田间土壤中播种了甜菜种子，揭示了 FA 的生物折叠特性。生物矿化和元素映射表明，在添加 15%FA 的土壤中补充营养元素可促进甜菜的生长表现和产量。在这项研究中，使用形态和分子特征化的Meloidogyne incognita作为线虫来优化 FA 的杀线虫特性。与对照（未处理和未接种）相比，植物生长表现、光合色素和甜菜产量因 M. incognita 而显著降低，而 15%FA 显著逆转了 M. incognita 的负面影响（P ）与对照植物相比。共聚焦激光显微镜证实，与对照相比，土壤中添加的 15%FA 可减少甜菜中线虫幼虫的侵袭。PCA（主成分分析）分别解释了无线虫植物和处理植物（M. incognita + FA）总数据变异性的 98.63%和 98.8%，这表明本研究中各种研究参数之间存在显著相关性。
