How can technology reduce the amount of fertilizer needed and nano-fertilizers is a new way to increase nutrients use efficiency in crop production?
Several areas of technology are showing promise in reducing the need for traditional fertilizers:
1. Precision Agriculture: This approach uses real-time data, like from drones or soil sensors, to understand field variations in nutrient levels. This allows for the targeted application of fertilizers only where and when crops need them, minimizing waste and maximizing efficiency.
2. Smart Fertilizer Application Systems: These systems integrate with precision agriculture data to dispense exact amounts of fertilizer based on specific areas within a field. This ensures efficient delivery and avoids blanket application, which can lead to over-fertilization and environmental issues.
3. Biofertilizers: These are naturally occurring or lab-created microorganisms that promote plant growth by fixing atmospheric nitrogen or enhancing nutrient uptake. They offer a sustainable and environmentally friendly alternative to synthetic fertilizers.
4. Cover Cropping: Planting cover crops between main planting seasons helps maintain soil health, suppress weeds, and fix nitrogen. This reduces the need for external fertilizers while improving soil fertility for future crops.
Nano-fertilizers are a promising new technology aiming to further enhance nutrient use efficiency. These fertilizers are created using nanotechnology, making them extremely small particles that can be more readily absorbed by plants. This potentially allows for smaller quantities of fertilizer to provide the same or even better results compared to traditional fertilizers. However, further research is needed to fully assess their long-term effectiveness, environmental impact, and cost-effectiveness for widespread adoption.
It's important to note that while technologies like nano-fertilizers offer exciting possibilities, they should be seen as complementary to other approaches like precision agriculture and soil health practices for a truly sustainable and efficient reduction in fertilizer use.
The fertilizer use efficiency in Nano form of fertilizer is 85 to 95 per cent where as in straight fertilizers say for Nitrogen it will be around 40% , for Phosphorus at the maximum 20% and Potassium about 60% only even after applying all the fertilizer use efficiency increasing tools/technologies.
By way of increasing fertilizer use efficiency (say for nano form, the fertilizer utilization efficiency is around 85 to 95%) the crop nutrient requirement is satisfied. Where as the use efficiency in straight fertilizers are at maximum of about 40, 20 and 60% only for Urea, SSP and MOP respectively. Hence going for high fertilizer nutrient efficiency form of fertilizers could reduce the quantity of fertilizer nutrient requirement of crops.
Remote sensing technologies, such as satellite imaging, offer farmers valuable insights into crop health and nutrient status. By identifying areas with nutrient deficiencies, farmers can target specific locations for fertilizer application, thereby minimizing wastage and chemical fertilizer usage. Nano fertilizer have large surface area and particle size less than the pore size of root and leaves of the plant which can increase penetration into the plant from applied surface and improve uptake and nutrient use efficiency of the nano- fertilizer. Nanofertilizers can provide a more efficient and cost-effective way to fertilize crops while reducing the environmental impact of fertilizer application. They are the product of promising new technology that can help to meet the increasing demand for food and improve agricultural sustainability. A nanofertilizer refers to a product that delivers nutrients to crops in one of three ways. The nutrient can be encapsulated inside nanomaterials such as nanotubes or nanoporous materials, coated with a thin protective polymer film, or delivered as particles or emulsions of nanoscale dimensions. Nano-nitrogen fertilizers (NNFs) have emerged as a promising technology in the field of agriculture, offering potential solutions to improve nutrient uptake efficiency, enhance crop productivity, and reduce environmental impacts.
