Farmers are benefitting from it and, in the long run, they are the finest choose, claims inventor Ramesh Raliya
‘Nano Urea’, a fertilizer patented and sold by the Indian Farmers Fertiliser Cooperative Minimal (IFFCO), has been permitted by the government for business use since of its possible to significantly cut down the import invoice, but numerous authorities have questioned the science fundamental its efficacy.
Prime Minister Narendra Modi, although inaugurating a Nano Urea generation plant at Kalol, Gujarat on May possibly 28, said, “…a tiny bottle (500 ml) of Nano Urea is equal to a person 50 kg bag of granular urea currently utilized by farmers”.
IFFCO’s Nano Urea is made up of nitrogen, an factor essential for plant growth, in the form of granules that are a hundred thousand times finer than a sheet of paper. At this ‘nano’ scale, which is about a billionth of a metre, elements behave in different ways than in the seen realm.
Ramesh Raliya, 34, who is credited as the inventor of Nano Urea and is now a expert with IFFCO, told The Hindu that his method works by using “organic polymers” that keeps the ‘nano’ particles of nitrogen stable and in a variety that can be sprayed on to vegetation.
Chemically, packaged urea is 46% nitrogen, which usually means a 45 kg sack has about 20 kg of nitrogen. Contrastingly, Nano Urea offered in 500 ml bottles has only 4% nitrogen (or all-around 20 gm). How this can compensate for the kilogrammes of nitrogen ordinarily necessary puzzles scientists.
Crops have to have nitrogen to make protein and they supply pretty much all of it from soil microbes which reside in a plant’s roots and have the ability to crack down atmospheric nitrogen, or that from chemical compounds these kinds of as urea, into a sort usable by crops.
To produce 1 tonne of wheat grain, a plant demands 25 kg of nitrogen. For rice, it is 20 kg of nitrogen, and for maize, it is 30 kg of nitrogen. Not all the urea forged on the soil, or sprayed on leaves in the case of Nano Urea, can be utilised by the plant. If 60% of the obtainable nitrogen were used, it would yield 496 kg of wheat grain. Even if 100% of 20 gm of Nano Urea, which is what is successfully offered, is utilised by the plant, it will yield only 368 gm of grain, stated N.K. Tomar, retired Professor of Soil Science at Chaudhary Charan Singh Haryana Agriculture University, Hissar, Haryana.
“Therefore, total attempt is futile resulting in sheer wastage of dollars. This declare of IFFCO is unfounded and will be disastrous for farmers,” he notes in a letter to the NITI Aayog as perfectly as the Nationwide Academy for Agricultural Sciences. Dr. Tomar instructed The Hindu they experienced not but responded to his letter.
His views are seconded by I.P. Abrol, retired former Deputy Director Basic, Indian Council of Agricultural Analysis (ICAR). “Urea is remarkably h2o soluble and previously reaches the least expensive variety of concentration when absorbed. How nanoparticles can raise the usefulness of nitrogen uptake by being continue to more compact is unclear to me. That foliar spraying (spraying on leaves) increases fertilizer uptake is known for more than 50 percent a century. So what’s new in this article?” Dr. Abrol requested.
In contrast to the coarse particles that farmers ordinarily toss on to the soil through sowing, the nano particle sort of Nano Urea, when applied on to the leaves, stimulates a assortment of enzymes, like nitrase and nitrite reductase, which will help vegetation metabolise nitrogen, Dr. Raliya explained.
Various areas of the plant comprise nitrogen in different proportions and simply because nano particles are so small and several, they have a good deal extra surface place relative to their volume, as opposed with the millimetre-dimension grains of urea that vegetation are exposed to — virtually 10,000 situations far more in nitrogen. “The conversation and metabolic process is vastly enhanced and for that reason the reaction (in phrases of yield) is a lot more. Get the smartphone — more compact batteries and processors are in a position to deliver as significantly ability as more substantial batteries after did because we use nanomaterials of carbon, titanium dioxide and graphene. The quantum effects of nanoparticles and the amplified area location make the nano particles in Nano Urea provide a lot more nitrogen,” Dr. Raliya defined.
There are still quite a few factors of plant action when uncovered to nano particles that are unclear and a issue of investigate. “I have several investigation papers on this and continue to a lot of queries. But we have benefits from experiments and that was the basis of why the product was authorized by governing administration. The farmers are benefitting from it and, in the long run, they are the best choose,” he included.
An agronomist affiliated to the Ministry of Agriculture who declined to be discovered mentioned that the maximize in yields that ended up observed in vegetation which been given Nano Urea was merely defined by the fact that in the very first calendar year, the nitrogen present in the soil and fertilizer was adequate, owing to which supplying nitrogen by way of Nano Urea was superfluous. “For example, you have cash in your pocket and each individual calendar year, you acquire a small out. At some stage, you’ll operate out,” he reasoned.
Dr. Raliya challenged this assertion. As aspect of his investigate work that led to the advancement of Nano Urea, he claimed he had examined if the Nano Urea was triggering depletion of soil nitrogen and it was not. “The sum of nitrogen in most plants is incredibly constrained, about 1%-1.5%. We saw that there was no reduction in nitrogen in the leaf, or soil,” he explained.
As portion of his investigate, there were checks completed to see if Nano Urea sprayed along with organic farming methods could compensate for packaged urea. “We observed there was no reduction of produce. However, you cannot wean farmers absent from packaged urea right away as these are deeply ingrained behaviours. More than the years, as farmers see benefits, they will by themselves utilize much less of the packaged urea,” mentioned Dr. Raliya, who completed his Doctoral experiments at the ICAR-Central Arid Zone Investigation Institute, Jodhpur, and will come from a farming spouse and children.
Trilochan Mohapatra, former Director Typical, ICAR, all through whose tenure the product or service was authorized, instructed The Hindu that though the verdict on the system of Nano Urea was nevertheless awaited, it was perfectly established that much of the urea now applied on the fields was wasted. “It is simple fact that 70% of the urea applied now is wasted. How considerably of that remaining 30% in fact helps make it to the plant relies upon on a multitude of elements from how you spray to the soil good quality. It’s achievable that the nano particles might be aiding effectiveness but evidence is awaited,” Dr. Mohapatra said.
