Summary
Net N mineralization and plant available N (assessed by seedling uptake) were shown to be enhanced by the presence of larch in mixed larch + spruce stands growing on deep peat. Estimates of N mineralization obtained by 120 day incubations and N uptake by birch seedlings were highly correlated, and showed excellent agreement with previous short-term field and laboratory incubation studies. net n mineralization after 30 days was highly correlated with cumulative net mineralization after 120 days, demonstrating that sample manipulation did not dominate initial results.
