다국어 초록 (Multilingual Abstract)

This study was carried out to find out a good qualified content of fertilizers and we had to experimented living 7 years tea plants on cultivating areas form such as divert tea plant upland from terraced paddy soil in local at Hadong-gun hwagae-myeon unsoo-ri 582-1, we had been studied from February 22 day of 2001 to October 30 day of 2003 The conclusions obtained were summarized as follow.
1. Experiment of soil in pH value was range 4.1~4.2 which there was necessary to reform in soil in order to pH range 5.5 grade by lime treated to soil(663~795kb/10a) and the number time of injection to soil was good as 3time over.
2. Content of available phosphate in soil was increased ranged from 129.5 to 138.3mg/kg than the former of experiment in soil as 64.8 mg/kg
3. The number of new tea leafs on the unit areas with tea plant were very much depending on application with N-P2O5-K2O-compost (17-14-14-700kg/10a) in soil such as a leaf of 2,292 also which it was high showed significance of interval years
4. Quantity of fresh leaves in tea plant application with N-P2O5-K2O-compost (17-14-14-700kg/10a) in soil was showed through the first collect of leaves range from 151.0 kg to 198.3 kg, the second collect of leaves range from 95.3 kg to 115.0 kb, the third collect of leaves range from 109.7 kg to 166.8 kg but the uantity of contain with tea pack was very much range from 1,039.9 kg to 1,139.1 kg
5. The first collect of leafs, were similar to content of total nitrogen, tannin, chlorophyll for N-P2O5-K2O-compost (17-14-14-700kg/10a) treatment in soil and N-P2O5-K2O-compost (17-14-14-700kg/10a) over treatment was showed high such as total nitrogen of 1.4%
6. In the case of tea pack was increased from content of crude fat, but tannin was decreased because of amount of many application with fertilizers in soil.
7. The recent of 3 years, farms had obtained to profits and income tax about 2,336won, 1.359won by application with N-P2O5-K2O-compost (17-14-14-700kg/10a) in soil compared with farmhouse of practice ratio 24.8%, but application with N-P2O5-K2O-compost (17-14-14-700kg/10a) treatment was a lot low.
Accordingly, I think that effect of quantity increased through treated with N-P2O5-K2O-compost (17-14-14-700kg/10a) in soil and the component parts of green tea not changes turn to naturally with faculty
