How increase the nutrient use efficiency by smart fertilizers and role of nano fertilizers in ensuring nutritional requirements of crop?
Smart Fertilizers and Nano Fertilizers: Boosting Nutrient Use Efficiency and Crop Nutrition
Smart fertilizers and nano fertilizers are two emerging technologies aiming to revolutionize agriculture by improving nutrient use efficiency (NUE) and ensuring proper nutritional requirements for crops. Here's how they each contribute:
Smart Fertilizers:
- Precision Delivery: These fertilizers utilize advanced technologies like sensors, GPS, and data analytics to monitor soil conditions and plant health. This allows for targeted application of fertilizers, delivering the right dose of nutrients at the right time and location. This reduces wastage and over-application, leading to improved NUE.
- Controlled Release: Some smart fertilizers incorporate controlled-release mechanisms, like coatings or encapsulated forms, that gradually release nutrients over time. This ensures a steady supply of nutrients to the plant, preventing them from leaching out before being utilized, again enhancing NUE.
Nano Fertilizers:
- Enhanced Absorption: Due to their incredibly small size, nano fertilizers offer a larger surface area for interaction with plant roots. This facilitates efficient uptake of nutrients by the plants, minimizing losses and maximizing utilization.
- Targeted Delivery: Similar to smart fertilizers, some nano fertilizers can be engineered to target specific nutrients to specific plant parts. This directed delivery optimizes nutrient utilization and reduces waste.
- Slow Release: Certain nano fertilizers can be designed to release nutrients slowly over an extended period, mimicking the natural nutrient release in soil. This sustained release ensures a constant supply of nutrients to the plant throughout its growth cycle.
Combined Impact:
By combining the benefits of both smart and nano fertilizers, we can achieve a synergistic effect on nutrient use efficiency and crop nutrition. Smart delivery systems can precisely apply nano fertilizers, maximizing their effectiveness. Additionally, data collected by smart systems can be used to tailor nano fertilizer formulations for specific crops and soil conditions.
Challenges and Future:
Both smart and nano fertilizers are still under development, facing challenges like cost-effectiveness, scalability, and potential environmental impact. However, ongoing research and innovation hold promise for overcoming these challenges, paving the way for a future where these technologies can contribute significantly to sustainable and efficient agriculture, ensuring optimal crop health and nutrition.
In order to enhance nutrient use efficiency, new types of smart fertilizers with controlled nutrient release are needed. The development of such fertilizers could be based on the use of microorganisms (biofertilizers) and/or nanomaterials (nanofertilizers). Nanofertilizers, on the other hand, use nanoparticles to control the release of nutrients, making them more efficient and cost-effective than traditional fertilizers. Nanofertilizers comprise one or more plant nutrients within nanoparticles where at least 50% of the particles are smaller than 100 nanometers. Nanofertilizers can increase the nutrient use efficiency, thus being beneficial for nutrition management. These nutrients are bound to the nano-absorbents that are applied either alone or in combination and release the nutrients at a slower rate than that of conventional fertilizers. Nanofertilizers in combination with biofertilizers have many advantages and open new approaches to sustainable agriculture. Nano-biofertilizers decrease mineral losses in fertilizing and increase the yield during mineral management as well as supporting agriculture development.
