Global climate change and increased population caused significant depletion of freshwater especially in arid and semi-arid regions including Saudi Arabia. Saline water magnetization before irrigation may help in alleviating the adverse effects of salinity on plants. The current study aimed to examine the potential beneficial effects of water magnetization and soil amendments on growth, productivity, and survival of L. plants. Three types of water (tap water "control", well water, and magnetized well water) and two types of soil amendments (FeSO and peat moss) were examined. Our results showed that irrigating . plants with saline well water (WW) adversely affected growth and flowering as compared to tap water (TW). However, plants irrigated with magnetized water (MW) showed significant enhancement in all the studied vegetative and flowering growth parameters as compared to those irrigated with WW. Furthermore, mineral contents and survival of . plants irrigated with MW were higher than those irrigated with TW. Irrigation with MW significantly reduced levels of NA and Cl ions in leaves of . plants indicating the role of magnetization in alleviating harmful effects of salinity. The current study showed that water magnetization enhanced water quality and increased plant's ability to absorb water and nutrients. Further studies are needed to examine the possibility of irrigating food crops with magnetized water.
全球气候变化和人口增长导致淡水资源大幅减少，尤其是在包括沙特阿拉伯在内的干旱和半干旱地区。灌溉前对咸水进行磁化处理可能有助于减轻盐分对植物的不利影响。本研究旨在探讨水磁化和土壤改良剂对L.植物生长、生产力和存活率的潜在有益影响。研究了三种类型的水（自来水“对照”、井水和磁化井水）和两种类型的土壤改良剂（硫酸亚铁和泥炭藓）。我们的结果表明，与自来水（TW）相比，用咸井水（WW）灌溉L.植物对其生长和开花产生了不利影响。然而，与用WW灌溉的植物相比，用磁化水（MW）灌溉的植物在所有研究的营养生长和开花生长参数方面均有显著提高。此外，用MW灌溉的L.植物的矿物质含量和存活率高于用TW灌溉的植物。用MW灌溉显著降低了L.植物叶片中钠和氯的离子水平，表明磁化在减轻盐分有害影响方面的作用。本研究表明，水磁化提高了水质，并增强了植物吸收水分和养分的能力。需要进一步研究探讨用磁化水灌溉粮食作物的可能性。
