“…The mineral composition of crops results from the uptake of nutrients from soil and/or foliar applications. The proper method of nutrient application depends in part on the type of fertilizer being applied, whether it is mineral [167], organic [168], a biofertilizer [169], nanofertilizer [170] or nano-biofertilizer [71]. Plant nutrition is also influenced by the environmental conditions around the plants, including abiotic and biotic stresses [171].…”

“…The advantages may include their higher target rate and delivery efficiency, less coagulation/aggregation, and higher stability at reaction sites [268]. Several studies have reported on nano-enabled agriculture and have focused on issues such as nano-enabled precision farming [17], nano-enabled farming [12,268], the nano-food industry [269], nano-enabled seed treatments [19,270], nanostructured manganese oxides [271], nano-enabled agrochemicals [88,170,272], and nano-Zn-enabled cropping systems [16]. Along with nano-enabled farming, nano-processed food products have shown great promise for a variety of applications in the food industry [269,273,274] using organic compounds such as chitosan [275], cellulose [276], and proteins [277].…”

The relationship between agriculture and food is very close. It is impossible to produce adequate crops for global food security without proper farm management. Farming practices represent direct and indirect controlling factors in terms of global food security. Farming management practices influence agro-food production from seed germination through to the post-harvest treatments. Nano-farming utilizes nanotechnologies for agricultural food production. This review covers four key components of nano-farming: nano-mushroom production, protein-based nanoparticles, nano-nutrients, and nanofibers. This provides a comprehensive overview of the potential applications of nanotechnology in agriculture. The role of these components will be discussed in relation to the challenges faced and solutions required to achieve sustainable agricultural production. Edible mushrooms are important to food security because they are a nutritious food source and can produce nanoparticles that can be used in the production of other food sources. Protein-based nanoparticles have considerable potential in the delivery of bioactives as carriers and other applications. Nano-nutrients (mainly nano-selenium, nano-tellurium and carbon nanodots) have crucial impacts on the nutrient status of plant-based foods. Carbon nanodots and other carbon-based nanomaterials have the potential to influence agricultural crops positively. There are promising applications of nanofibers in food packaging, safety and processing. However, further research is needed to understand the impacts and potential risks of nanomaterials in the food production system.

“…Conventional pesticide formulations may lead to adverse ecological and environmental problems due to the majority of the applied pesticides being lost to the environment and only less than 1% being effectively utilized at the intended target . As an alternative approach, the delivery of the pesticides can be accomplished by stimuli-responsive controlled release systems, which prolong the lifetime of the pesticide molecules and make them resistant to external factors such as rainwater leaching or photodegradation, thereby enhancing their effectiveness and enabling the use of lower dosages. − Controlled pesticide release systems triggered by different external stimuli have been demonstrated in the literature. − Xiang et al designed a pH-responsive attapulgite-based hydrogel pesticide release system and characterized its release behavior in aqueous solutions at varying pH values . Kaziem et al developed an enzyme-responsive insecticide delivery system based on surface-functionalized hollow mesoporous silica loaded with insecticide and capped with α-CD, which is designed to release the pesticide cargo upon hydrolysis triggered by the presence of α-amylase .…”

A controlled release system that enables the sunlight-triggered release of a model agrochemical, abamectin (abm), is presented. The release system consists of polydopamine functionalized halloysite nanotubes (HNT-PDA) utilized as photothermal nanocarriers to encapsulate 25 wt % abm and 37 wt % lauric acid (LA), a phase change material, that acts as a heatactivable gatekeeper stopping or facilitating the abm release. When exposed to sunlight for 20 min at 1 and 3 sun light density, the temperature of the photothermal nanocarriers reaches 51 and 122 °C, respectively, which triggers the melting of LA and the consequent release of abm from the nanocarriers. Abm was shown to be released gradually over a period of 10 days when nanohybrids were exposed to sunlight for 6 h per day and to remain stable and kill Myzus persicae (Sulzer) (Hemiptera: Aphididae), green peach aphids, at a mortality rate of over 70% for at least 10 days. Aqueous dispersions of the LA/abm@HNT-PDA nanohybrids were studied in terms of their potential as aqueous sprayable pesticide nanoformulations and presented over 30% suspensibility, 36 mg/cm 2 foliar retention, strong rainwater resistance, and a 50% mortality rate for M. persicae at a concentration of 9 mg/mL. The proposed sunlight-activated controlled release system based on photothermal, LA-functionalized HNT-PDA nanocarriers holds great potential as controlled release pesticide nanoformulations.

“…Nano-farming refers to the application of nanomaterials (NMs) or nanoparticles (NPs) in agricultural production [34]. This can be performed in different ways, including nano-priming of seeds to increase germination through the regulation of ROS [35], nanofertilization to increase crop productivity during the growing season [36], nano-pesticide application for plant protection [37], nano-sensors to support smart farming [38,39], nanoharvest [40] or nano-postharvest [41,42] applications to reduce food spoilage, and plant nano-bionics to enhance or modify plant functions [43]. Nanomaterials have the potential to enhance the productivity of crops by improving the delivery of nutrients, managing pest control, and supporting crop stress resilience [44].…”

Increased heat stress is a common feature of global climate change and can cause adverse impacts on crops from germination through maturation and harvest. This review focuses on the impacts of extreme heat (>35 °C) on plants and their physiology and how they affect food and water security. The emphasis is on what can be done to minimize the negative effects of heat stress, which includes the application of various materials and approaches. Nano-farming is highlighted as one promising approach. Heat is often combined with drought, salinity, and other stresses, which together affect the whole agroecosystem, including soil, plants, water, and farm animals, leading to serious implications for food and water resources. Indeed, there is no single remedy or approach that can overcome such grand issues. However, nano-farming can be part of an adaptation strategy. More studies are needed to verify the potential benefits of nanomaterials but also to investigate any negative side-effects, particularly under the intensive application of nanomaterials, and what problems this might create, including potential nanotoxicity.
