Evaluation of Soil Fertility Quality of Tea Gardens in Eastern Fujian

Ten tea gardens in eastern Fujian were tested for their soil pH, organic matter, total nitrogen, available phosphor, exchangeable kalium, exchangeable magnesium, exchangeable calcium, available manganese, available cuprum, available boron and available zinc for the quality determination. These indices were subjected to the fuzzy comprehensive evaluation. The IFI value significantly correlated with the yield of the spring tea. Hence, the soil fertility could be well defined by using these indices. The fertility of the tea gardens in the eastern Fujian regions was above average, that is, 60% of them were higher and 40% lower than the national average.
