Some Short-term Effects of Lime and Fertilizers on a Sitka Spruce Plantation
II. Laboratory Studies on Litter Decomposition and Nitrogen Mineralization
Agricultural and Chemistry Department, Queen's University of Belfast, and Ministry of Agriculture Northern Ireland
Laboratory incubation experiments show that lime, applied in the field or immediately before incubating, increases the rate at which Sitka spruce needles and forest floor litter decompose. Increases in CO2 production caused by lime were accompanied by the rapid assimilation of both native and added mineral N. Added mineral N also increased CO2, produced from lime-treated spruce needles. Results are related to field data reported in the first paper of this series.
