摘要
Due to the considerable profit made by planting tea trees on the high mountains in Taiwan, farmers fertilized their tea farms with about 600 kg of N/ha/y and 210 kg of P/ha/y to maintain a high production. However, the tea trees utilized only 5% of the fertilizer, and the remaining 95% of nitrogen and phosphorus were lost. The lost nitrogen and phosphorus caused a problem of eutrophication in the downstreams of a reservoir. The best management practices of the tea farm is to reduce 20% dosage of the fertilizer. Also, the reduction of the 20% can still ensure not to damage the good quality of the tea production.
