Preliminary data from-this experiment indicate that yield of Leatherleaf fern is
increased by addition of manganese, but reduced by addition of iron. Plots which
received 50 pounds of manganese per acre per year (with no iron) produced approximately
565,000 fronds per 30,000 square feet per year. This study was conducted for only 1
year, thus continual application of manganese may result in phytotoxicity and reduced
yield. Based on this data, we would not suggest application of manganese at rates
higher than 50 pounds per acre the first year and after the first year, would not
suggest addition of manganese at more than 25 pounds per acre per year.

Fern beds established for 18 months were treated with various leveTsof-iron-ani
manganese sequestrenes for 1 year. Additions of iron and manganese were applied at
monthly intervals at rates that totaled 0, 25, and 50 pounds per acre per year. A
total of 500 pounds nitrogen per acre per year was supplied from an 8-8-8 granular
fertilizer applied at 3 month intervals. Fernery was maintained at 350F minimum,
during winter months.
