Nutrient Status of Tea Garden Soil in Lingyun County and Rational Fertilization Countermeasure

In order to study the nutrient status of the tea garden soil of Lingyun County,30 soil samples were collected from the representative tea garden of Lingyun County,and 12 important soil fertility indexes were determined.The results showed that the pH value was suitable for growth of tea,and the organic matter content was relatively high in tea garden soil.The total nitrogen and water-soluble nitrogen content was relatively high but the contents of available phosphorus and available potassium were low.The content of secondary-micro elements was low except available copper.According to the soil nutrient status,it was recommended to increase the rates of organic,phosphate and potassium fertilizers,decrease the rate of nitrogen,and keep the balance of secondary-micro element fertility.
