Abstract

Nanotechnology has rapidly expanded across various fields, yet its application in agriculture remains underexplored. This study investigates the impact of zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles on maize cultivation, comparing commercial samples with those synthesized by combustion reaction. Synthesized ZnO and ZnO/MgO (1:1 by mass) were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM) to determine particle size and morphology. The experimental design assessed the effects of different treatments on magnesium and zinc uptake in maize roots and leaves, using atomic absorption spectrometry (AAS) for analysis. Results indicate that commercial ZnO significantly increased Zn absorption compared to synthesized samples and the control group, highlighting the influence of particle size and surface area on nutrient uptake. This study provides valuable insights into the potential of nanomaterials into the plant’s absorption mechanism as well as show that the availability of Zn NP synthesized contributes to the absorption of zinc by the plant without competing with Mg. On the other hand, when in Zn commercial, Mg absorption may be impaired.

应用于玉米土壤的商品和通过燃烧反应合成的纳米微粒氧化锌和氧化镁的吸收率

纳米技术已在各个领域迅速发展，但其在农业中的应用仍未得到充分探索。本研究比较了商用样品和通过燃烧反应合成的样品，研究了氧化锌（ZnO）和氧化镁（MgO）纳米颗粒对玉米栽培的影响。使用 X 射线衍射 (XRD)、傅立叶变换红外光谱 (FTIR) 和透射电子显微镜 (TEM) 对合成的氧化锌和氧化锌/氧化镁（质量比为 1:1）进行表征，以确定粒度和形态。实验设计采用原子吸收光谱分析法（AAS）评估了不同处理对玉米根和叶镁和锌吸收的影响。结果表明，与合成样品和对照组相比，商用氧化锌能显著提高锌的吸收率，突出了颗粒大小和表面积对养分吸收的影响。这项研究为了解纳米材料在植物吸收机制中的潜力提供了有价值的见解，并表明合成的锌氧化物有助于植物对锌的吸收，而不会与镁发生竞争。另一方面，在锌商业化的情况下，镁的吸收可能会受到影响。

期刊介绍： Environmental Nanotechnology, Monitoring and Management is a journal devoted to the publication of peer reviewed original research on environmental nanotechnologies, monitoring studies and management for water, soil , waste and human health samples. Critical review articles, short communications and scientific policy briefs are also welcome. The journal will include all environmental matrices except air. Nanomaterials were suggested as efficient cost-effective and environmental friendly alternative to existing treatment materials, from the standpoints of both resource conservation and environmental remediation. The journal aims to receive papers in the field of nanotechnology covering; Developments of new nanosorbents for: •Groundwater, drinking water and wastewater treatment •Remediation of contaminated sites •Assessment of novel nanotechnologies including sustainability and life cycle implications Monitoring and Management papers should cover the fields of: •Novel analytical methods applied to environmental and health samples •Fate and transport of pollutants in the environment •Case studies covering environmental monitoring and public health •Water and soil prevention and legislation •Industrial and hazardous waste- legislation, characterisation, management practices, minimization, treatment and disposal •Environmental management and remediation
