| Abstract: | According as the systematic approach for soil nutrient status,the nutrients limiting factors of the young oil-teasoil in Yichun of Jiangxi were studied.The result displayed that the main nutrients limiting factors of young oil-tea soil were N, P, Ca and the yields would be reduced by 63.97%, 61.32% and 19.08% without N, P, Ca. |
