Abstract:
These data contain biochemical parameters as measured in foliage of three ericaceous shrubs as part of a long-term fertilization experiment at Mer Bleue bog in Ottawa, Ontario, Canada. Velvetleaf blueberry, Bog Labrador tea and Leatherleaf were experimentally treated with Nitrogen (N) and Nitrogen + Phosphorus + Potassium (N+P+K) at levels 5 and 20 times greater than the ambient growing season wet Nitrogen deposition (0.8 grams of Nitrogen per square meter per year [g N m⁻² yr⁻¹]). There were a total of 5 treatments (control, 5N, 5NPK, 20N, 20NPK); each treatment had three replicate plots 3 × 3 m in size. Nitrogen as Ammonium Nitrate (NH4NO3) and Nitrogen + Phosphorus + Potassium as Ammonium Nitrate + Potassium Phosphate (NH4NO3 + KH2PO4) was dissolved in distilled water and applied in soluble form as an application of 2 millimeters at 3-week intervals from early May to late August. Control plots were treated with distilled water. Three treatment applications began in 2000, the 20N treatment was added in 2005. Foliar sampling took place in 2008, which was eight and three years after initiation, respectively. Data includes free polyamines, free amino acids, soluble ions, chlorophyll and soluble proteins that were analyzed using an HPLC, ICP, and spectrophotometer.
