Litter quality and decomposition in Danthonia richardsonii swards in response to CO2 and nitrogen supply over four years of growth

Abstract

Litter quality parameters of Danthonia richardsonii grown under CO2 concentrations of ~359 and ~719 μL L-1 at three mineral N supply rates (2.2, 6.7 and 19.8 gm-2y-1) were determined. C:N ratio was increased in senesced leaf (enhancement ratios, R(e/c),
