Eucalyptus trees around rice fields can provide benefits like acting as windbreaks, reducing soil erosion, and improving drainage, but they may also compete for water and light and release chemicals that inhibit crop growth. Proper management is essential to balance these effects. The current study was undertaken to explore the effects of eucalyptus trees along boundaries on the chemical composition of rice field's soil. In the northern region of Bangladesh, in the Bogra district, surface soils were collected from rice fields. Inductively coupled plasma mass spectrometry (ICP-MS) technique was used to analyze these samples. The pH of most soil samples was less than 7.0, suggesting a slight acidity. Furthermore, the sub-surface soil samples (214.4, 174.3, and 159.3 µS/cm) had slightly higher electrical conductivity (E.C.) values than the surface soil samples (10.3, 178.3, and 154.3 µS/cm). Significant variations in soil chemical properties such as organic matter content, soil moisture, availability of phosphorus, sulphur, sodium, calcium, potassium, magnesium, copper, zinc, manganese, and iron were observed across different distances from eucalyptus boundaries. These variations reflect the influence of eucalyptus trees on soil characteristics. A considerable portion of nickel, copper, and zinc was detected in the strongly bound residual phase, while arsenic, cadmium, and lead were bound to carbonate and exchangeable fractions. This research indicates that planting eucalyptus trees could potentially enhance soil fertility in agricultural fields, particularly in areas with concentrated agriculture near industrial zones. The novelty of this research lies in identifying the positive impacts of eucalyptus boundary plantations on soil properties in rice fields.
稻田周围的桉树能带来诸多益处，比如充当防风林、减少土壤侵蚀以及改善排水，但它们也可能会与水稻争夺水分和光照，并释放抑制作物生长的化学物质。恰当的管理对于平衡这些影响至关重要。本研究旨在探究边界种植的桉树对稻田土壤化学成分的影响。在孟加拉国北部的博格拉区，从稻田采集了表层土壤样本。采用电感耦合等离子体质谱（ICP-MS）技术对这些样本进行分析。大多数土壤样本的pH值小于7.0，表明土壤呈微酸性。此外，下层土壤样本（214.4、174.3和159.3微西门子/厘米）的电导率（E.C.）值略高于表层土壤样本（10.3、178.3和154.3微西门子/厘米）。在距桉树边界不同距离处，观察到土壤化学性质存在显著差异，如有机质含量、土壤湿度、磷、硫、钠、钙、钾、镁、铜、锌、锰和铁的有效性等。这些差异反映了桉树对土壤特性的影响。在强结合残留相中检测到相当一部分镍、铜和锌，而砷、镉和铅则与碳酸盐和可交换部分结合。这项研究表明，种植桉树有可能提高农田土壤肥力，尤其是在工业区附近农业集中的地区。本研究的新颖之处在于确定了桉树边界种植对稻田土壤性质的积极影响。
