Micronutrient concentrations vary between peat–mineral mix and substrates in revegetated sites in the Alberta oil sands

摘要: Adequate supply of micronutrients is essential for plant growth in reclaimed sites the Athabasca oil sands region. The objectives this study were to determine boron, iron, manganese, copper, and zinc concentrations peat–mineral mix (PMM), tailings sand (TS), overburden (OB) materials assess whether lodgepole pine (Pinus contorta) planted on PMM over TS white spruce (Picea glauca) OB had low foliar micronutrient concentrations. Micronutrient determined using LiNO3 Mehlich-3 extractions different between while only extractable boron was (p   iron > manganese > zinc > copper all soil layers with ranging from 0.04 39.56 μg g−1. concentration copper consistent both s...
