摘要

为了农业生产的可持续性，熟悉土壤质量和人为改进以创造最佳的植物生长环境是非常重要的。在这项研究中，研究了北Vanlaiphai水田土壤质量与全年季节变化的关系。在稻田不同地点选取5个土壤样品，采用标准方案对土壤肥力指标pH、土壤全氮(N)、速效磷(Pav)、交换性钾(Kex)、土壤有机碳(SOC)、土壤有机质(SOM)和土壤酶脱氢酶、磷酸酶和脲酶进行分析。除有效磷和交换性钾外，其余各参数均在雨季最高，夏季最低。

Effect of seasonal variation on soil enzymes activity and fertility of soil in paddy fields of North Vanlaiphai, Mizoram, India

For sustainability in agricultural productions, familiarity of soil quality and manual improvement to create the best possible growing environment for plants are extremely important. In this study the quality of soil of a paddy field in North Vanlaiphai was investigated with respect to the change in seasons throughout the year. A total of five (5) soil samples were selected from various places of the paddy field, and soil fertility indicators such as pH, total soil nitrogen (N), available phosphorus (Pav), exchangeable potassium (Kex), soil organic carbon (SOC), soil organic matter (SOM) and soil enzymes viz. dehydrogenase, phosphatase and urease were analyzed using standard protocols. All the parameters except available phosphorus and exchangeable potassium were found to be highest during rainy season whereas lowest in summer.
