Leaf nutrient ranges for wild blueberries in Prince Edward Island.

摘要

Leaf samples were collected from 61 wild blueberry fields in Prince Edward Island (PEI), Canada, from 2003 to 2005 and analyzed for macro- and micronutrient content. Leaf samples were collected at the terminal abortion stage, which is usually early to mid-August from sprout-year fields only. Results of leaf samples were summarized for minimum, maximum, and mean concentrations. Mean leaf nutrient concentrations were 1.51 nitrogen (N), 0.127 phosphorus (P), 0.51 potassium (K), 0.59 calcium (Ca), 0.16 magnesium (Mg), 0.22 sulfur (S), 2.8 ppm copper (Cu), 32.0 ppm boron (B), 11.4 ppm zinc (Zn), 21.6 ppm iron (Fe), and 1351 ppm manganese (Mn). All elements except for Mn are described by the mean+or-1 standard deviation (SD).
