Nanotechnology for Blue and Green Revolution
The use of nanoscale structures in technology and medicine has already infiltrated daily life in countless ways. A range of applications in areas of sensors, coatings, hybrid materials, catalysis and biocatalysis and drug delivery are presently exploited.
Although there is significant work done on use of nanoparticles in agriculture and aquaculture their use as nutrients in this field is poorly understood.
Here in we explore the enormous potential of a patented nanosilica based nano nutrient mixture this PRODUCT on wide range of applications like Bioremediation, Aquaculture and Crop protection
This PRODUCT is patented nano silica based nano nutrient mixture in size range of 5-100 nm. The silica becomes both the carrier for other nutrients and the nutrient by itself. It is in a water dispersible particulate form having the important micronutrient -iron (0.01% to 50% of Fe) and the other micronutrients- Mn, Zn, Co, Cu, Mo, B, S, Ca, Mg, P, K,and mixtures thereof in the proportion 0.001% to 30% of the weight of silica. PRODUCT because of its nanosize is able to pervade very small spaces in the subsurface and remain suspended in water, allowing the particles to travel farther than larger, macro-sized particles there by increasing the bioavailability of the nutrients for easy absorption by plants and micro algae and achieve wider distribution. The iron and other micronutrients in nano form cannot precipitate out or gel in the water as it happens when they are added directly as salts.
Mechanism of action in aquatic system (Blue revolution):
This PRODUCT contains all the micronutients required for growth of microscopic plants called Micro algae particularly diatoms. Diatoms are a major group of eukaryotic micro algae and are one of the most common types of phytoplankton. They are especially important in oceans, where they are estimated to contribute up to 45% of the total oceanic primary production and 25% of global oxygen output. Diatoms are responsible for up to 20% of the global CO2 fixation. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica due to this unique nature diatoms are well adapted in bioaccumulation of silica and with out it they cant survive. As PRODUCT is nano silica base micro nutrient mix it is readily absorbed by diatoms.
Shrimp hatcheries, fish ponds and other commercial aquaculture facilities grow diatoms as they are the main source for poly unsaturated fatty acids(PUFA's). When compared with other traditional media used in culture of diatoms PRODUCT containing medium showed a significant increase in growth of diatoms.
Microalgae especially diatoms possess many advantages to be useful for aquacultured species as Natural food:
• They are appropriate size and shape for ingestion and ready digestion,
• They provide food for zooplankton,
• They contain ideal biochemical composition (e.g. accumulation compounds, enzymes and toxins) and specific requirements of the target animal.
• As primary producers in the aquatic food chain, microalgae provide many phytonutrients, including in particular PUFAs - e.g. EPA, arachidonic acid (AA) and DHA
This PRODUCT can be used in Sewage Treatment, Lake and River Remediation. Almost all the lake and river ecosystems contain enormous amount of N and P which are major nutrients for diatom growth but they lack in silica which is required for diatom growth. As diatoms consume co2 and release o2 the growth of diatoms using PRODUCT automatically increases the aeration in polluted water bodies there by reduces COD and increases BOD this in turn will help in enhanced biological activity, decrease in foul odor and fish production.
PRODUCT causes sudden diatom bloom, release oxygen, which can be seen from the appearance of bubbles within minutes of dissolving of PRODUCT in polluted water bodies. It is estimated that the use of 1 liter of PRODUCT releases at least 200 Kg of oxygen by absorbing 275 Kg of carbon dioxide. Diatoms also bioaccumulate heavy metals like cadmium, Arsenic and Lead there by reducing heavy metal poisoning of aquatic organisms. PRODUCT reduces the growth of blue green algae there by keeping the water surface clear which in turn helps in aeration. PRODUCT is successfully used in bioremediation of polluted lakes India and USA.
Bioremediation using diatoms grown with PRODUCT has the potential to reduce the overall costs of cleaning up large-scale contaminated sites, reduce cleanup time, eliminate the need for treatment and disposal of contaminated dredged soil, and reduce some contaminant concentrations to near zero, and it can be done in situ.
Mechanism of action in Terrestrial system (Green revolution):
PRODUCT contains micronutrients in nano form which are essential ingredients for plant growth and because of their nano size they can be easily absorbed by leaves directly this mechanism of absorption directly through leaves greatly reduces the use of soil based nutrient enrichment were there is risk of nutrient loss through different environmental factors. This mechanism is also efficient as the nutrients are delivered to the reaction centers in fast and efficient manner. Silicate which is the major nutrient present in PRODUCT is also known to induce disease resistance, Increases the leaf area and thus enhances photosynthectic capacity, decreases the leaf curl and early leaf fall there by improves assimilation.
Applications of PRODUCT foliar spray:
• PRODUCT when used as foliar spray helped in reduction of early leaf fall and discoloration of leaves in banana.
• It also induced increased flowering in mango there by increasing the over all yield.
• prevented leaf curl in tomato plants, leaf burning in potato plants, chlorosis in sapota leaves and nut drop in coconut trees, besides increasing their fruit sizes,
• PRODUCT speeded up the growth of Napier grass from 45 days to 25 days
• The product was tested on paddy in the Department of Rice Research (an ICAR lab) at Hyderabad and was found to improve the yield.
• The product is tested in KSSRDI at Talaghatpura, India on mulberry plants that are used to grow silk worms. It showed no toxic effect in silk worm rearing.
The use of nano nutrients is fast emerging as a potent, convenient and cost effective alternative for traditional nutrient delivery. This invention emphasizes the potential of nano particles in key areas like agriculture, aquaculture and bioremediation. There are many potential uses which are still to be explored. The results of scientific endeavour at the nanoscale continue to progress our understanding, allowing us to maximise the potential of nanotechnology within informed restrictions. Where knowledge lays the boundaries, a little imagination adds wings, and the current state of research in nanonutrients seems well set to take flight.
