Selenium is an essential micronutrient that plays a vital role in maintaining soil health, crop productivity, and ecosystem sustainability. Selenium influences soil microbial communities, affecting microbial diversity, composition, and functional genes. It also impacts soil physicochemical properties, such as pH, organic matter, and nutrient availability. Selenium has the potential to enhance crop resilience to abiotic stressors, including drought, salinity, and extreme temperatures. It triggers antioxidant defense, osmotic adjustment, and hormonal regulation, allowing crops to withstand stress. Selenium's role in modulating soil microbiome and crop stress tolerance has important implications for sustainable agriculture. The relationships between selenium, arable soil microbiome, and crop resilience are complex and multifaceted. Selenium's benefits for crop productivity and stress tolerance make it a valuable tool for improving agricultural sustainability. The application of selenium in agriculture has the potential to improve crop yields, reduce soil degradation, and promote ecosystem services. However, excessive selenium levels can have negative environmental and health impacts, highlighting the need for careful management and regulation. By understanding selenium's role in soil health and crop resilience, we can develop innovative strategies for promoting ecosystem sustainability and ensuring global food security. Thus, this chapter contributes to our understanding of the complex relationships between selenium, soil microbiome, and crop resilience, and highlights the potential of selenium as a valuable tool for improving crop stress tolerance.

摘要

Selenium is an essential micronutrient that plays a vital role in maintaining soil health, crop productivity, and ecosystem sustainability. Selenium influences soil microbial communities, affecting microbial diversity, composition, and functional genes. It also impacts soil physicochemical properties, such as pH, organic matter, and nutrient availability. Selenium has the potential to enhance crop resilience to abiotic stressors, including drought, salinity, and extreme temperatures. It triggers antioxidant defense, osmotic adjustment, and hormonal regulation, allowing crops to withstand stress. Selenium's role in modulating soil microbiome and crop stress tolerance has important implications for sustainable agriculture. The relationships between selenium, arable soil microbiome, and crop resilience are complex and multifaceted. Selenium's benefits for crop productivity and stress tolerance make it a valuable tool for improving agricultural sustainability. The application of selenium in agriculture has the potential to improve crop yields, reduce soil degradation, and promote ecosystem services. However, excessive selenium levels can have negative environmental and health impacts, highlighting the need for careful management and regulation. By understanding selenium's role in soil health and crop resilience, we can develop innovative strategies for promoting ecosystem sustainability and ensuring global food security. Thus, this chapter contributes to our understanding of the complex relationships between selenium, soil microbiome, and crop resilience, and highlights the potential of selenium as a valuable tool for improving crop stress tolerance.
