Abstract

The application of plastic mulch and pesticides is common practice in intensive agriculture in Indonesia. However, their effects on soil fertility are still uncertain. Therefore, this study was aimed to determine the effect of plastic mulch and pesticide application on the soil fertility of Andisol. The experiment was conducted in an intensive agriculture field in West Sumatra and the treatments included were: plastic mulch and pesticide application with two levels of each. Treatments were arranged in a completely randomized design with three replications. The result shows that there were significantly high in pH, total N and exchangeable Mg when using plastic mulch while organic C was found to be low in a plot with the application of pesticide. Meanwhile, the interaction between plastic mulch without pesticide showed a significantly higher in exchangeable Mg. The result suggested that the plastic mulch practice can sustain the availability of nutrients in the soil while the usage of pesticides can reduce the organic C in the soil besides its main function to protect the crops.

地膜覆盖和施用农药对安地醇化学性质的影响

在印度尼西亚，使用塑料覆盖物和杀虫剂是集约化农业的普遍做法。然而，它们对土壤肥力的影响仍不确定。因此，本研究旨在确定地膜覆盖和施用农药对安迪索土壤肥力的影响。试验在西苏门答腊岛的一个集约化农田进行，处理包括:地膜覆盖和农药施用，每两个水平。处理采用完全随机设计，3个重复。结果表明，地膜覆盖显著提高了土壤pH、全氮和交换态镁的含量，而施用农药的土壤有机碳含量较低。与此同时，无农药地膜互作显著提高了土壤中可交换性镁的含量。结果表明，地膜覆盖可以维持土壤养分的有效性，而农药的使用除了具有保护作物的主要功能外，还可以降低土壤中的有机碳。
