Agricultural sustainability implications in using nanocellulose composite for delaying nitrogen release

Area of Science:

• Agricultural Science
• Materials Science
• Environmental Science

Background:

• Conventional nitrogen fertilizers suffer from low nitrogen use efficiency (NUE), leading to unsustainable agricultural practices.
• The development of slow-release nitrogen fertilizers (SR-N) offers a more efficient and environmentally friendly approach to crop nutrition.
• Nanocellulose is emerging as a promising biopolymer for SR-N due to its abundance, biodegradability, and unique properties.

Purpose of the Study:

• To review the application of nanocellulose as a matrix and coating material in slow-release nitrogen fertilizer (SR-N) designs.
• To explore the implications of nanocellulose-based SR-N for sustainable agriculture.
• To highlight the benefits of nanocellulose in enhancing nutrient availability and soil properties.

Main Methods:

• Review of scientific literature on nanocellulose applications in fertilizer technology.
• Analysis of nanocellulose properties relevant to nutrient release and soil interaction.
• Synthesis of findings regarding the impact of nanocellulose on soil microbial communities and plant growth.

Main Results:

• Nanocellulose serves as an effective matrix and coating for SR-N, enabling gradual nutrient release.
• Its high hydrophilicity and hydroxyl groups aid in water retention and nutrient delivery.
• Nanocellulose incorporation enhances soil microbial diversity, nitrogen fixation, and organic matter decomposition.
• Surface modifications of nanocellulose can be tailored to control nitrogen release rates, improving crop productivity and regulating crop composition.
• Delayed nitrogen release from nanocellulose-based fertilizers significantly reduces agricultural emissions.

Conclusions:

• Nanocellulose is a viable and sustainable material for developing advanced slow-release nitrogen fertilizers.
• Nanocellulose-based SR-N contributes to enhanced crop yield, improved soil health, and reduced environmental pollution.
• Further research should focus on cost-effectiveness, scalability, application methods, field variability, and regulatory aspects for widespread adoption.
