1. Importance of Nano Science & Nano Technology In Agriculture “Nano Technology is the art and science of manipulating matter at nano scale.” 1.1. Importance of Nano Technology: Nanoscale science and technology, often spoken of as “nanoscience” or “nanotechnology,” are simply science and engineering carried out on the nano-meter scale, that is, 10−9 meters. Nano science is an important and emerging field in the other fields of science. The implications of nanotechnology are wide-ranging and could include medicine, military applications, computing and astronomy. Nano technology is being used already in certain materials like self-cleaning glass, sunscreens, and even antibacterial socks. Nanotechnology has great potential, as it can enhance the…show more content…
The agricultural sector will benefit greatly from nanotech-based tools to detect diseases in a rapid manner, improve the ability of plants to absorb nutrients and promote molecular treatment of diseases. Some of the important applications of agriculture are given below: 1.1.1. Nano Scale Carriers: Nanoscale carriers can be utilized for the efficient delivery of fertilizers, pesticides, herbicides, plant growth regulators, etc. The mechanisms involved in the efficient delivery, better storage and controlled release include: encapsulation and entrapment, polymers and dendrimers, surface ionic and weak bond attachments among others. These mechanisms help improve stability against degradation in the environment and ultimately reduce the amount to be applied, which reduces chemical runoff and alleviates environmental problems. 1.1.2. Nano Fertilizers: Fertilizer play pivotal role in the agriculture production up to 35 to 40% of the productivity. To enhance nutrient use efficiency and overcome the chronic problem of eutrophication, nonfertilizer might be a best alternative. Attempts have been made to synthesize nonfertilizer to regulate the release of nutrients depending on the requirements of the crops, and it is also reported that nonfertilizer are more efficient than ordinary…show more content…
When cotton is processed into fabric or garment, some of the cellulose or the fibres are discarded as waste or used for low-value products such as cotton balls, yarns, and cotton batting. With the use of newly-developed solvents and a technique called electrospinning, scientists produce 100 nanometre-diameter fibres that can be used as a fertilizer or pesticide absorbent. These high-performance absorbents allow targeted application at desired time and location. 1.1.6. Clay nanotubes: Clay nanotubes (Hallo site) have been developed as carriers of pesticides for low cost, extended release, and better contact with plants, and they will reduce the amount of pesticides by 70–80%, hence reducing the cost of pesticide and the impact on water streams. 1.1.7. Starch-based nanoparticles: Agricultural nanotechnology has vast range of applications in sustainable production techniques. Starch-based nano-containers play a key role for the transport of bio stimulants and crop protection molecules to plant tissues. The basic purpose of using starch is that it is biocompatible, biodegradable and nontoxic for plants as well as for environment. Variety of molecules can be transported by means of starch nano-containers. Starch based nano-containers can also be used for long term feeding of plants at slow rate, as biostimulant compounds can also be slowly released through nanocontainers according
