“…To date, various mineral sprays have been tested, most of which are selenite, silicate, and zinc fertilizers. Generally, all three types of foliar sprays were shown to be effective in grain Cd reduction irrespective of the climatic region, soil type, and crop variety (Gao et al, ). Se and Si sprays seemed to reduce rice grain Cd by regulating Cd translocation from roots to grains (Gao et al, ).…”

Se and Si sprays seemed to reduce rice grain Cd by regulating Cd translocation from roots to grains (Gao et al, ). Both Si and Se fertilizers have long been recognized as beneficial to plant stress responses (Z. Chen, Chen, & Chen, ; Feng, Wei, & Tu, ; Zhu, Wei, Li, Qian, & Yu, ), and they are now becoming a cost‐effective and practical agronomic measure for crop heavy metal reduction.…”

China is suffering from farmland heavy metal pollution. Different strategies have been explored in the past decades to address the problem, mainly metal removal, substitute planting, and safe farming. Safe farming aims to produce metal‐safe food crops in heavy metal‐polluted farmland without purposefully removing the excess metals. Safe farming was intended to address the soil‐borne food heavy metal issue and has been advocated as a priority solution for farmland pollution by the government. Many conventional and novel technologies have been tested for safe farming in recent years. Although most reduced heavy metals in grains, none of the technologies alone were found to be sufficient in field practice to meet national food standards. The current best practice is recognized as the combination of several agronomic measures, including pollution‐safe cultivars, optimal water management, liming, and conventional metal immobilizers. Unfortunately, field trials have not achieved a robust technical framework effective for farmland with different soil properties and climatic conditions. We propose that a practical technical framework may be biotechnology centered with a minimal use of chemical immobilizers, particularly liming and phosphate minerals. Foliar sprays and microbial biosorbents seem promising for safe farming. A biotechnology‐centered framework may largely simplify the field practice of safe farming and is more acceptable to governments and farmers.

BackgroundNanotechnology, utilizing nanoparticles (NPs) with unique physicochemical properties, has significant potential in enhancing sustainable agriculture through innovations in plant nutrition, growth, and protection.AimsThis review aims to assess how nanotechnology, particularly NPs, contributes to sustainable agriculture by improving plant nutrition and growth, enhancing stress resistance, and offering solutions for phytoremediation and agricultural efficiency.MethodsWe examine studies showcasing the application of NPs in agriculture, focusing on their effects on plant growth, nutrient delivery, stress mitigation, pollutant removal, and the enhancement of food shelf life through nano‐encapsulated fertilizers and nano‐sensors.ResultsNPs have demonstrated promising results in slow‐release fertilizers for targeted nutrient delivery, improved germination and physiological activity under stress, and enhanced efficiency in phytoremediation by aiding the removal of pollutants. Nano‐sensors in food packaging detect deterioration and extend food shelf life, whereas nano‐encapsulation of agrochemicals offers environment‐friendly pest and nutrient management solutions.ConclusionsNanotechnology presents a forward‐looking approach to sustainable agriculture by enhancing crop productivity, resource use efficiency, and environmental protection. Continued research is essential to unlock the full potential of NPs in agriculture, emphasizing safe and efficient application methods to mitigate abiotic and biotic stresses and promote sustainability.
