Modes of Selenium Application in Agriculture: Efficacy and Issues

Abstract

Selenium (Se) is a micronutrient that plants require in trace levels to operate properly. Special agriculture, sometimes referred to as se-rich farming, that capability to boost crop productivity (Huang et al. 2023). Selenium presents in agricultural systems from all sources (Bano et al. 2021). Organic form or as elemental Se (Fe2(SeO3)3, and Na2SeO3) that’s main selenium source in soil (Yamada et al. 1999). SeO2−4 SeO2− 3 and are two highly soluble anionic type of selenium that plants may absorb, are typically found in soils (Dinh et al. 2019). Generally, garlic, onions, brassicaceae and some mushroom types have high Se concentrations, while the majority of agricultural crops have poor tolerances Se content as less than 50 mg/kg. (Yin et al. 2019). Plants selenium concentration can rise using Se fertilization (Kapolna et al. 2009; Broadley et al. 2010). According to many research investigations, judicious management of selenium, even at low amounts, can enhance plant development (Bano et al. 2021).
