symptoms of manganese deficiency
brown flecks (barley), yellow areas turn grey (oats), interveinal chlorosis (beet)
soils most likely to show manganese deficiency
high ph, organic, sandy
what is molybdenum needed for

symptoms of molybdenum deficiency
interveinal chlorosis, incomplete leaf development with only veins being formed
soils most likely to show molybdenum deficiency
acidic or sandy soils
