Clay-Nanocomposite Based Smart Delivery Systems: A Promising Tool for Sustainable Farming

Abstract

Clay-nanocomposite materials have been widely exploited as drug delivery systems, but their application in agriculture is less explored. In clay-nanocomposite, the combination of nanoclay and the active ingredient (i.e., metal, nonmetal, oxide nanoparticles) can produce a biocompatible and environmentally friendly delivery vehicle of micronutrients, pesticides, etc. for better crop growth. Clay-nanocomposites have been researched to address the problem of nontarget effects of agrochemicals, their leaching into groundwater, and the fast breakdown of sprayed chemicals. Here, we present a review of the synthesis of clay-based nanocomposites and their application as a delivery vehicle for agrochemicals and nucleic acids, as well as their antimicrobial properties. This review would be helpful in identifying and addressing the current issues of the delivery of active ingredients and biological macromolecules for crop protection, improved growth, and sustainability.

Advancements in rice disease detection through convolutional neural networks: A comprehensive review

“…Red yeast rice ingredients such as monacolin K (lovastatin) and GABA are known for their health benefits in reducing the risk of circulatory diseases [ 46 ]. The availability of active ingredients to rice farmers in various countries is extensive and encompasses a wide array of compounds used for crop protection, nutritional enhancement, and medicinal purposes [ 47 ].…”

Nanobiotechnology to advance stress resilience in plants: Current opportunities and challenges

“…1 ). Furthermore, ENMs can improve nutrient utilization by targeted delivery, creating affordable resource recovery strategies, developing plants into smart sensors to predict the upcoming stress, creating more resilient cultivars through genetic modifications, improving the management of crops to avoid crop losses, enhancing microbiome to replenish soil quality and elevate plant growth [ 13 ]. These steps can result in an improved yield by utilizing fewer resources and avoiding environmental collateral damage.…”

Iron Nanostructure Primes Arbuscular Mycorrhizal Fungi Symbiosis Tightly Connecting Maize Leaf Photosynthesis via a Nanofilm Effect

“…It is essential to distinguish the contributions of nanoscale structural properties and nutrient properties when assessing the effects of nanomaterials on plants. , In this study, high- and low-dose nanoscale zerovalent iron (nZVI) and iron sulfate (FeSO 4 ) were applied in maize seedlings, respectively, to further identify the differences in the effects of two types of iron components on plant–AMF symbionts. Also, the mechanisms underlying the differential functional effects of nZVI and FeSO 4 on plant–AMF symbionts were investigated.…”
