Abstract:
In order to understand the soil nutrient status of cultivated land in Jian'ou City, 294 soil samples from 0-20 cm soil layer of cultivated land in Jian'ou City were collected in 2017, and the soil pH and the contents of organic matter, alkali nitrogen, available potassium, available phosphorus and exchangeable calcium, exchangeable magnesium, available sulfur, available zinc and available boron were measured. The results showed that the soil pH value of cultivated land in Jian'ou City was acidic and above, with an average of 4.85. The contents of organic matter and alkali nitrogen were in the upper middle, with an average of 26.78 g·kg
-1 and 122.60 mg·kg
-1, respectively. The contents of effective phosphorus was abundant, with an average of 51.62 mg·kg
-1; the contents of available potassium was moderate, with an average of 101.45 mg·kg
-1; the contents of exchangeable calcium, available zinc and available sulfur are abundant, with an average of 637.74 mg·kg
-1, 3.78 mg·kg
-1, 40.08 mg·kg
-1, respectively; the content of exchangeable magnesium was moderate, with an average of 79.01 mg·kg
-1; the content of effective boron was deficient, with an average content of 0.47 mg·kg
-1.
