Abstract
Abstract The objective of this study was to analyze the abundance and deficiency status of soil nutrient in tea plantations. By the methods of matter-element model, the plentiful-lack condition of soil nutrients were evaluated from single indicators and integrated indicators on the basis of the analysis in a small-scale soil nutrient status in tea plantation soils of Mengding Mountain. The results showed that (1)Soil nutrient levels were low in tea plantation, and the distribution of total nitrogen, total phosphorus, total potassium concentration was obviously concentrated. The distribution of alkali-hydrolysable nitrogen, available phosphorus and potassium dispersed highly and alkali-hydrolysable nitrogen was most obvious. (2) Soil nutrient levels of single indicator mainly concentrated in low and marginal, and nearly 90% of the integrated indicator of soil nutrient factors were in a state of the middle and low level.
