Analysis on Soil Nutrients Status of Niaowang Tea Origins in Guiding County

This paper analyses the soil nutrients status of Niaowang tea origins in Guiding county,and classifies the soil fertility according to the soil nutrients status of tea gardens in Guizhou.The results show that the soil nutrient distribution of Niaowang tea origins is not balanced and the variation range of soil nutrient contents among different regions is great.The soil samples with organic matter and hydrolysate nitrogen moderate account for above 85% and active phosphorus and active potassium lower grades account for 90%in total tested samples.Organic matter and active phosphorus content level of Niaowang tea origins are higher and soil active phosphorus and active potassium content level are lower.
