| Mass loss and changes of mineral nutrients during decomposition of Lepista nuda for 7 weeks from October 7 to December 28 in 1998 were investigated in an oak stand in Kongju, Korea. Content of nitrogen, phosphorus, potassium, calcium and magnesium of the fresh L. nuda was 67.8, 4.1, 47.3, 0.4 and 1.5 §·/g, respectively. Content of nitrogen, phosphorus and potassium in L. nuda were much higher than those in leaf litter. After 7 weeks, remaining mass was 35%. Nitrogen, phos- phorus and potassium increased till 5 weeks and then decreased rapidly, however, calcium and magnesium steadily increased during the experimental period. Nitrogen and phosphorus showed a short period of immobilization, and calcium showed no immobilization period during decomposition. After 7 weeks, remaining N, P, K, Ca and Mg was 26.6, 37.5, 28.5, 35.0 and 91.0% of the initial content, respectively. Nutrients could be relocated spatially during the formation and decomposition of fruiting body of Basidiomycetes. |
