ABSTRACT:
The recent years have seen a sharp increase in interest in nanotechnology because of its numerous uses in fields such materials science, medicine, pharmaceuticals, energy, and catalysis. There are numerous possible uses for such nanoparticles with small to large surface areas (1-100 nm). Sustainable agriculture is necessary today. The creation of nanochemicals has shown promise as insecticides, fertilizers, and agents for plant growth. Utilizing nanomaterials as an alternate means of controlling plant pests, such as weeds, fungus, and insects, has gained attention in recent years. Food packaging uses a variety of nanomaterials as antibacterial agents; silver nanomaterials, in particular, are of particular interest. A variety of nanoparticles, including carbon nanotubes, Ag, Fe, Cu, Si, Al, Zn, ZnO, TiO2, CeO2, and Al2O3, have been shown to have negative impacts.
INTRODUCTION:
The world needs creative ways to produce high-quality, larger-scale agricultural products because of the current issues it faces, including an expanding population, climate change, deteriorating soil quality, and food security. The application of nanotechnology to agriculture is one such remedy. Agricultural engineering has recently embraced nanotechnology, using nanomaterials to create a range of technologies for uses in sustainable agriculture. By bringing efficiency, precision, environmental stewardship, and kindness to the agricultural landscape, nanotechnology catalysis sustainable agriculture. From the initial stages of seed germination to the last phases of food processing, nanotechnologies have permeated both upstream and downstream operations. Nanoscale coverings improve the viability, nutrient uptake, disease resistance, germination stage, and seed quality of seeds. Crop health, water use, and soil quality are all monitored and controlled by nano sensors and nano biosensors. Nano-enabled delivery systems maximize efficacy and minimize waste by accurately applying growth regulators, insecticides, and fertilizers as crops mature. Furthermore, food processing, food preservation, intelligent packaging,quality control, post-harvest losses, and shelf life are all aided by nanotechnology. It provides a sustainable way to feed the world's expanding population by maximizing resource use, enhancing crop resilience, and cutting waste; yet, the study and application of nanotechnology in agriculture creates opportunities for creativity and further developments. The primary obstacles that need to be solved are those related to soil health, environmental concerns, cost-effectiveness, and health risks associated with the use of nanomaterials in agricultural activities. nanotechnology's potential to revolutionize agriculture by enhancing crop yield, quality, cost-effectiveness, soil health, and environmental sustainability. Embracing nanotechnology ensures food security and environmental stewardship for future generations, making it a crucial tool in addressing global agricultural challenges.
APPLICATION IN AGRICULTURE ENGINEERING:
Nanomaterials in Remediation:
Nanomaterials for Remediation of Soils to selectivity, adaptability, and high reactivity, nanotechnology and nanomaterials (NMs) have shown important and novel ways to solve many challenges in soil remediation. Because contaminated groundwater and soil interfaces are complex and heterogeneous, remediating them has revealed significant economic and technological challenges. The issues are with the in-situ zones, getting the target contaminants to interact and mix effectively, and remediation.
Nano-insecticides:
In agriculture, pesticides are typically employed to increase crop yields and efficiency. Urea, a source of urease, nitrite, and nitrate that cause eutrophication in water, is the most widely used pesticide fertiliser to increase crop yields. The worldwide urea market forecast for 2020 states that 187.8 million metric tonnes of urea are needed; by 2026, that number might rise to 211.5 million metric tonnes. Neonicotinoids, carbamates, atrazines, and organo-phosphates are a few examples of pesticides.
Nano biosensors:
Plant industry applications for nanobiosensors Compared to conventional biosensors, nanobiosensors (NBSs) have improved selectivity and sensitivity. NBSs provide real-time signal monitoring and can identify harmful microbes directly or indirectly. NBSs are arranged as nanotubes, nanoparticles, nanocrystals, or nanowires, with dimensions of no more than 100 nm, and are put together to observe plant fractions, water, and soil in agroecosystems. NBSs represent a powerful instrument with superior features over current biosensors and analytical sensors.
Packaging and nanotechnology:
Food industries are leading in forming the food with good nutritive value. For example, high impermeable packaging nanomaterials are used for protection of food from UV radiations and providing more strength to maintain the food protected from environment, increasing their shelf lives. Nanosensors are used for the detection of chemicals, gases and pathogens in food. In modern terminology, a word is given to such type of packaging as smart packaging. Some studies suggested that people are not accepting the direct involvement of nanoparticles in food due to some risk factors. Therefore, it is needed to provide some safety measurements to reduce the risk and human safety.
Antimicrobial Nano Coatings:
Antimicrobial nano coatings have emerged as a revolutionary technology in agriculture engineering, providing a robust solution against microbial contamination and infection. These coatings utilize nanoparticles to inhibit the growth of harmful microorganisms, ensuring improved crop yields, reduced pesticide usage, and enhanced food safety.
Antimicrobial nano coatings are employed in agriculture engineering to prevent microbial contamination and infection in crops, seeds, soil, irrigation systems, and agricultural equipment, utilizing nanoparticles like zinc oxide, copper, and silver to inhibit fungal and bacterial growth, reduce pesticide residues, enhance crop yields by 20-30%, improve seed germination by 25-40%, extend shelf life of fruits and vegetables by 30-50%, minimize water contamination, protect agricultural infrastructure, reduce post-harvest losses by 20-30%, and improve food safety, while also reducing environmental pollution, enhancing agricultural sustainability, and promoting organic farming practices.
FUTURE SCOPE AND CHALLENGES:
By extending novel approaches like plant nutrient absorption capacity, disease detection, climate-smart agriculture, and more effective and efficient input utilization and management, nanotechnology will modernize and transform the food and agricultural industries. Many technological advancements, such hybrid cultivars, synthetic fertilizers, and pesticides, have a major positive impact on agriculture. Crops are shielded by agrochemicals from weeds, pests and different agricultural illnesses.
CONCLUTION:
Numerous applications of nanotechnology, such as food processing, ecological remediation agents, nano biosensors, nano pesticides, nano priming, and nano fertilizers, are found in sustainable agriculture. On the other hand, comprehending how nanomaterials affect the environment in agriculture including soil health and pesticide usage remains a difficult task. For the purpose of developing effective, affordable, and environmentally acceptable nanomaterials as well as comprehending.
