Recent Advances in Agricultural Selenium Chemistry.

Area of Science:

• Agricultural Chemistry
• Human Health and Nutrition
• Trace Element Research

Background:

• Selenium (Se) is an essential trace element vital for human health.
• Widespread Se deficiency affects 70% of China and a global belt across Eurasia, impacting over a billion people.
• Current Se supplementation strategies face challenges, necessitating innovative agricultural solutions.

Purpose of the Study:

• To systematically review the development of Se fertilizers.
• To analyze the limitations of existing Se fertilizer types (natural mineral, inorganic, nano-Se).
• To evaluate the application value of selenized glucose as a novel organoselenium source for Se-enriched cultivation.

Main Methods:

• Literature review of Se fertilizer development history.
• Comparative analysis of Se fertilizer types and their application defects.
• Focus on the efficacy of selenized glucose in Se-enriched agriculture.

Main Results:

• Natural mineral, inorganic, and nano-Se fertilizers exhibit application defects.
• Selenized glucose emerges as a new generation organoselenium source.
• Selenized glucose shows significant potential for Se-enriched cultivation.

Conclusions:

• Addressing global Se deficiency requires advancements in agricultural selenium chemistry.
• Innovations in Se fertilizer technology are crucial for effective Se supplementation.
• Selenized glucose represents a valuable and promising approach for Se-enriched agriculture and mitigating Se deficiency.
