摘要
生态系统的功能和良性互动取决于土壤的物理和化学特征以及养分状况。这些土壤养分对植物的生长和发育至关重要,在各种基本功能中发挥着关键作用。本研究调查了孟加拉国吉大港山区 Bandarban Sadar Upazila 不同土地利用方案和土壤深度下土壤养分模式的动态变化。研究重点是林地、农田和荒地等三种不同土地利用方式下两种土壤深度(0-15 厘米和 15-30 厘米)的土壤养分含量分布情况。采用分层随机抽样设计,从研究区域收集了约 90 个土壤样本。分析结果显示,这些土地利用类型和土壤深度之间的土壤 pH 值、有机质 (OM)、全氮 (TN)、磷 (P)、钾 (K) 和硫 (S) 含量存在显著差异。研究结果表明,农田的土壤 S 含量和 pH 值通常较高,相比之下,林地的 OM、TN、P 和 K 含量相对较高。同样,与农田和林地相比,贫瘠土地的 pH 值和 S 含量相对较高。此外,表层土壤(0-15 厘米)的养分含量普遍高于深层土壤(15-30 厘米)。调查发现,OM 与土壤养分(如 TN、P、K 和 S)之间存在明显的正相关关系,这表明它们之间存在相互影响。总之,研究成果强调了在这一具有重要生态意义的地区采用可持续土地管理方法来保持土壤肥力和优化土壤生产力的重要性。
Variations of Soil Organic Matter and Nutrients in Diverse Hilly Soils of Bandarban, Bangladesh
Functioning and positive interactions in an ecosystem depend on physical and chemical features of soil, along with nutrient status. These soil nutrients are vital for the growth and development of plants, playing a crucial role in various essential functions. The current study investigates the dynamic changes in soil nutrient patterns across different land use scenarios and soil depths at Bandarban Sadar Upazila, Chittagong Hill Tracts, Bangladesh. The research focuses on how soil nutrient levels are distributed in two soil depths (0-15 cm and 15-30 cm) among three different land use practices, such as forest land, agricultural land and barren land. About 90 soil samples from the study area were collected using a stratified random sampling design. The analysis reveals significant variations in soil pH, organic matter (OM), total nitrogen (TN), phosphorus (P), potassium (K), and sulfur (S) levels among these land use types and soil depths. The findings revealed that agricultural land typically exhibited higher levels of soil S content and pH, in contrast to forested areas where OM, TN, P, and K levels were comparatively more abundant. Again, barren land showed a relatively higher pH and S content than agricultural land and forest land. Additionally, the topsoil (0-15 cm) generally showed higher nutrient content than the deeper soil layer (15-30 cm). The investigation uncovered significant positive correlations of OM with soil nutrients such as TN, P, K & S, indicating mutual influences on their availability. Overall, the research outcomes emphasize the importance of sustainable land management practices to maintain soil fertility and optimize soil productivity in this ecologically significant region.
