Fertilizers are chemical compounds applied to promote plant growth. It is applied either through the soil or by foliar feeding. Artificial fertilizers are inorganic fertilizers formulated in appropriate concentration to supply the nutrients. Nitrogen is an important source which is essential for the growth of plant. Urea is the most widely used water soluble plant nitrogen source.
Another beneficial aspect of using nanofertilizers is the ability to provide slow release of nutrients into the plant over a 4050 days time period, rather than the 410 days period of conventional fertilizers. In the present article, we have briefly discussed appliion of nanotechnology in a agricultural perspective.

Mar 01, 2021 · Kampeerapappun, P. Phanomkate, N. Slow release fertilizer from coreshell electrospun fibers. Chiang Mai J. Sci. 40, 775–782 (2013). CAS Google Scholar
Nitrogen release of the nanofertilizer composition was studied using soil from three elevations in Sri Lanka (pH, and 7) and compared with that of a commercial fertilizer. The nanofertilizer showed an initial burst and a subsequent slowrelease even on day 60 compared to the commercial fertilizer, which released heavily early followed ...
Dec 11, 2020 · The release rate also depends on the type and thickness of the coating. Release rate customizations by crop are manufactured based on projected growing season temperatures, crop growth cycle and crop needs. Most assume this type of technology is the same as a "slow release" fertilizer, but that is not the case with controlled release ...
Jan 25, 2017 · While slow release of chemicals has been widely applied for drug delivery, little work has been done on using this general nanotechnologybased principle for delivering nutrients to crops. In developing countries, the cost of fertilizers can be significant and is often the limiting factor for food supply. Thus, it is important to develop technologies that minimize the cost of fertilizers ...
SlowRelease Fertilizer: Higher Crop Yield, Less Environmental Harm. BCC Research identifies the controlled release of a substance as a niche appliion because it comes at a premium and it's used only during selected appliions. One such niche is the agricultural market. In developing countries, the cost of fertilizer remains relatively ...
Scientists have recently begun to look at this intractable problem through the lense of nanotechnology (5). That it has taken several decades for this paradigm shift in thinking may be the result of lack of research funding and a low level of innovation in the area of fertiliser.
Feb 18, 2019 · Smart fertilizers like slow and controlled release fertilizers, nanofertilizers and bioformulation fertilizers are the new technologies to enhance the nutrient use efficiency their by improving crop yield in sustainable manner. The use of slow and controlled release fertilizers increase nutrient use efficiency, minimize the risks like leaf ...
