Influence of Silicie Acid on Uptake of Mn, Al, Zn, and Cu by Tomatoes (Lycopersicum esculentum) Grown on an Acid Soil

Abstract

Abstract Treatment of an acid Merrimac fine sandy loam with H 2 SiO 3 significantly decreased the concentration and total uptake of Mn and Al in tissues of greenhouse grown tomatoes ( Lycopersicum esculentum ) but affected neither the uptake nor tissue concentrations of Cu or Zn. Yields of dry matter were not significantly increased by Na 2 CO 3 treatments. Increases in yield of dry matter were more closely associated with decreased concentrations of Zn and Cu and less closely associated with decreased concentrations of Al and Mn.
