Effective Removal of Silica Particles from Crops through Harvesting Techniques

This study explores the strategies for removing silica particles from higher plants (crops) during harvesting. It focuses on the significant quantity of SiO (approximately 27.5 million tons of Si per year) and evaluates the role of Si(OH) and monosilicic acid in the crop cycle, citing application rates of 20 to 250 kg Si/ha annually. The research highlights the dissolution of soil silicates and aluminosilicates into soluble forms, including Si(OH) which plays a crucial role in nutrient uptake. Additionally, it discusses the leaching of these soluble Si forms and their implications for crop health and yield.
