ABSTRACT
Nano fertilizers have emerged as a cutting-edge innovation in agricultural practices, poised to redefine nutrient delivery and management at the plant-soil interface. This review provides a comprehensive overview of the effects and consequences of nano fertilizer application on plant wellness. The inherent properties of nanoparticles allow for enhanced nutrient absorption, precise delivery, and increased bioavailability, potentially revolutionizing traditional fertilization methods. The results, as evidenced by multiple studies, indicate significant improvements in growth parameters, seed production, and overall plant health. Moreover, plants treated with nano fertilizers have shown heightened resistance to both biotic and abiotic stresses. However, while the benefits are promising, concerns arise regarding the ecological persistence of nanoparticles, potential bio-magnification, and implications for human health. A comparative analysis with conventional fertilizers revealed nano fertilizers' superior efficiency, but also brought forth economic considerations and environmental footprints. The current regulatory landscape is dynamic, with policies adapting to the rapid advancements of nanotechnology in agriculture. As research continues to bridge existing gaps, technological advancements are concurrently shaping the future prospects of nano fertilizer application. This review underscores the need for a balanced understanding of the potential and challenges, emphasizing collaborative efforts to harness nano fertilizers' full potential while ensuring ecological and human health safety.
ABSTRACT
Agriculture, as one of the oldest and most essential human endeavors, has constantly evolved through the integration of technology. In recent years, nanotechnology has emerged as a pivotal tool, redefining traditional agricultural paradigms. This comprehensive review delves into the multifaceted implications and applications of nanotechnology within agriculture, providing a holistic view of its past, present, and future roles. Historically, nanotechnology's initial foray into agriculture sought to tackle prevalent challenges, from pest control to soil fertility. Despite some early obstacles, this merger has since showcased myriad successful applications, underscored by targeted and efficient solutions that significantly enhance crop yield and food quality. The present-day agricultural landscape is punctuated by nano-fertilizers ensuring optimal nutrient uptake, nanopesticides targeting pests with minimal off-target effects, nanosensors enabling precision agriculture, nano-based food packaging enhancing shelf life, and nanomaterials aiding in disease diagnosis and treatment. However, with innovation come challenges. The environmental and health ramifications of introducing nanoparticles into ecosystems remain a concern. While they promise reduced chemical usage and waste, potential issues like nanoparticle accumulation, unknown long-term effects, and possible toxicity necessitate rigorous research and regulation. Economically, the nano-agri sector promises substantial yield increases, but it also requires significant investments. As the technology permeates the agricultural supply chain, ramifications on job markets, trade dynamics, and global competitiveness become evident. Looking forward, anticipated advancements include smart nanodevices, potent nano-bio interfaces, and self-repairing materials. Nanobots, soil health rejuvenation techniques, and advanced nano-encapsulation are among the many potential R&D avenues. The road ahead requires collaborative efforts from governments, research institutions, farmers, and the private sector. Public-private partnerships, in particular, could prove indispensable, merging public sector oversight with private sector innovation.
