Soil Factors Associated with Manganese Deficiency of Urban Sugar and Red Maples    (View PDF)

E. Thomas Smiley, J. James Kielbaso, and Phu V. Nguyen

Abstract: Manganese deficient and healthy Acer saccharum and Acer rubrum were sampled for foliar nutrient concentration and rated for chlorosis. Soil beneath trees was analyzed for pH, organic matter content, oxidation reduction potential, texture, calcium carbonate accumulation, and extractable manganese. Soil pH and summer rainfall were most strongly correlated with foliar manganese concentration and symptoms. Soil redox potential, organic matter, and extractable manganese were less strongly correlated.
