Foliar nutrient concentrations in balsam fir as affected by soil drainage and methods of slash disposal

Abstract

Foliar nutrient concentrations in young balsam fir grow- ing on strip clearcuts were assessed in relation to soil drainage and three methods of slash disposal. Concentrations of N, K, and Mn were higher for trees growing on well-drained soils than for trees growing on poorly drained soils. Mo concentrations were higher on poorly drained soils and all other measured nutrients were un- affected. Only foliar Fe was affected by the three methods of slash disposal.
