Nano fertilisers: Parliamentary report suggests close audit of field trials to see long-term effects

An audit by Division of Fertilisers discovered 25-50% variation in saving nitrogen use after making use of nano urea

Analysis trials on the results of nano fertilisers on the dietary high quality of crops have solely been carried out for a 12 months and only one season for many circumstances. Lengthy-term results, due to this fact, cannot be drawn at this stage, famous a Parliamentary Standing Committee on Chemical substances and Fertilisers.

Nano fertilisers are extremely environment friendly kind of fertilisers that present vitamins like nitrogen to crops by way of high-quality granules. Nitrogen is a vital macronutrient for plant capabilities. Urea is one of the most concentrated nitrogenous fertilisers, which readily converts to ammonia within the soil.

Nano urea liquid was developed in 2022 by the most important cooperative on the earth, Indian Farmers and Fertiliser Cooperative (IFFCO), to switch typical urea and curtail its requirement by 50 per centA 500-millilitres spray bottle can substitute a full 45-kilogramme bag of urea.

It has been closely promoted by the federal government since its growth. 

The committee on chemical compounds and fertilisers, in its report titled ‘Nano-Fertilisers for Sustainable Crop manufacturing and Sustaining Soil Well being’, really helpful a radical audit of the sector trials on making use of nano fertilisers. 

Nano fertilisers exploit the nanoscale porous domains on plant surfaces to ship vitamins, according to a study published in journal Nature. In addition they enhance the effectiveness of nitrogen supply and cut back the losses to the setting.

The savings in topdress nitrogen with the applying of nano urea throughout discipline trials was discovered to range between 25 to 50 per cent, the committee learnt. Topdressing is the method of including a second spherical of nitrogen to crops to compensate for any deficiencies. 

The panel steered an audit for various crops in numerous areas by the Division of Fertilisers in coordination with different ministries/organisations to evaluate the explanations behind the large variation in nitrogen saving whereas topdressing. 

The report mentioned: 

The committee need {that a} thorough audit of the sector trials on utility of nano fertilisers could also be obtained carried out by the Division in coordination with different ministries/organisations, to evaluate the explanations for large variation (25 to 50 per cent) in topdress nitrogen saving on totally different crops and in numerous areas, by the premier agricultural analysis institutes, and many others.

The explanations for variance and results must be scientifically analysed. Crop-specific procedures on how to appropriately apply nano urea to minimise or take away the variance vary must be formulated, the panel added. 

A concerted long-term devoted analysis by masking all the key crops in all of the agroclimatic areas and soil sorts of the nation was additionally steered by the committee.

It will assist totally assess the merits and demerits of using nano fertilisers and set up dietary high quality, bio-safety, efficacy and reliability of the harvested produce of nano fertilisers handled crops.

This examine, the report mentioned, must be carried out by the division with Division of Agricultural Analysis & Schooling (DARE) and Indian Council of Agricultural Analysis (ICAR), all of the agricultural universities and fertiliser manufacturing corporations. 

In the meantime, the report additionally took be aware of how the usage of nano urea may help the federal government save roughly $3 billion (round Rs 24,687 crore) in subsidy payments yearly and cut back India’s dependence on urea imports.

Nano fertilisers are additionally mentioned to value lower than subsidised typical fertilisers, leading to lower input costs for the farmers

The committee additionally urged the division and IFFCO to expedite the method of inclusion of different nano fertilisers, which have been developed by the multi-state cooperative and undergone ample discipline trials.

After nano urea, analysis trials of Nano Di-ammonium Phosphate (DAP) are additionally underway. In the course of the Kharif season of 2021, IFFCO has carried out Nano DAP analysis trials on 10 crops throughout 34 areas in 20 states underneath the Nationwide Agriculture Analysis System (NARS). 

Nonetheless, the results of these trials haven’t been submitted to Authorities of India for analysis, the report mentioned. 

IFFCO had been engaged within the analysis and growth of nano fertilisers since 2017.

They’ve developed nano fertiliser macronutrients grades like Nano Nitrogen and Nano DAP, and secondary or micronutrient grades like Nano Zinc, Nano Copper, Nano Boron, Nano Sulphur, and many others at Nano Biotechnology Analysis Centre in Kalol, Gujarat.
