Elemental composition of Miscanthus biomass grown on different kinds of Technosols

Abstract

ABSTRACT Miscanthus has been grown on four kinds of Technosols. These soil materials have relatively low levels of macronutrients and imperfect nutrient balance. Even so, miscanthus is able to produce substantial, stable yields from the third year of cultivation. The poorest yields were obtained on dark-grey schist clay; the highest on loess-like loam and red-brown clay. Miscanthus actively accumulates macronutrients, especially sulphur, whereas sodium and magnesium are accumulated in the smallest amounts; potassium and phosphorus are mainly accumulated in the stems, calcium and sulphur in the leaves.
