The Impact of Acid Rain on Crops and Countermeasures

This paper examines the contributing factors to acid rain formation, its effects on crops, and relevant research developments. The formation of acid rain is influenced by both anthropogenic and natural factors. On the anthropogenic side, industrial production, residential fuel combustion, and the emission of sulfur and nitrogen oxides from motor vehicles all contribute to its generation. On the natural side, volcanic eruptions and the decomposition of flora and fauna may also play a role. Acid rain poses significant threats to crops: it accelerates soil acidification, alters soil structure, disrupts microbial populations and nutrient cycles, and causes direct damage to crops. Different crop species exhibit varying sensitivities to acid rain. Recent research has made considerable progress in elucidating the mechanisms of harm and exploring prevention and control strategies, which holds significant implications for mitigation efforts.
