Abstract

[Objectives] This study aimed to provide a basis for the management of nitrogen, phosphorus and potassium nutrients in eum-orthic anthrosols and the fertilization of crops. [Methods] Using the indoor culture method, the contents of total nitrogen, available phosphorus and available potassium in eum-orthic anthrosols under three different moisture conditions: long-term drying, long-term logging and alternate drying and logging were analyzed and compared. [Results] The total nitrogen content was higher under the moisture condition of long-term drying. The minimum (0.60 g/kg) appeared on day 30, and the maximum (0.74 g/kg) appeared on day 120, increased by 8.8% compared with the minimum. The available phosphorus content was also higher under the moisture condition of long-term drying. The minimum (16.9 mg/kg) appeared on day 60, and the maximum (22.5 mg/kg) appeared on day 120, increased by 33.1% compared to the minimum. The available potassium content showed a downward trend under long-term logging, and was higher than those under the other two moisture conditions. The maximum (150 mg/kg) appeared on day 30, and the minimum (136 mg/kg) appeared on days 75 and 90, reduced by 9.3% compared with the maximum. [Conclusions] Water plays a positive role in activating nutrients. Different nutrients have different responses to different moisture conditions.
