What are the limitations of nano fertilizers and does Nano- fertilizers towards sustainable agriculture and environment?
Lack of production and availability of nano fertilizers in required quantities. This limits the wider scale adoption of nano-fertilizers as a source of plant nutrients. Lack of standardization in the formulation process. Nanofertilizers (NFs) are the best alternative to traditional chemical fertilizers. Nutrients use efficiency of NFs is higher than the conventional chemical fertilizers. NFs can increase the tolerance of plants against biotic and abiotic stresses. Nanofertilizers offer benefits in nutrition management through their strong potential to increase nutrient use efficiency. Nutrients either applied alone or in combination, are bound to nano-dimensional adsorbents, which release nutrients very slowly as compared to conventional fertilizers.
@ RK, the major limitations of nanofertilizers are:
1. Requirement is less that's why with time soil becomes deficient in nutrient unless and until you use chemical or biofertilizer as subsidy.
2. Lack of production and availability.
3. Lack of standardization and adoption of the protocol.
4. Cause pollution with higher doses as they are very soluble and mobile.
5. They may change the nature in soil making too acidic or alkaline.
Nano fertilizers have various limitations like:
1. Nano fertilizers are not produced in sufficient amounts.
2. Readily not available.
3. Due to less proction and availability of nano fertilizers restricts the use as a source of plant nutrients on a larger scale.
4.The procedure of formulation is not standardised.
5. After spray of nano fertilizer some time crop injury takes place.
Towards sustainable agriculture and environment:
Although the use of chemical fertilisers increases food production, their excessive and unbalanced use pollutes the soil and aerial environment, disrupting ecosystems. The improvement of food production with the least amount of environmental harm is made possible by the creation of NFs. These nanoparticles not only significantly improve environmental and agricultural sustainability but also mitigate the negative effects of conventional fertilizers.
Nanotechnology applications include nanoparticle-mediated gene or DNA transfer in plants for the development of insect-resistant varieties, food processing and storage and increased product shelf life. Nanotechnology may increase the development of biomass-to-fuel production. Nanofertilizers (NFs) are the best alternative to traditional chemical fertilizers.

The main benefits of green nanotechnology are: increased energy efficiency, reduced waste and greenhouse gas emissions, and minimized the consumption of non-renewable raw materials
