Respecting fertilizer application, the metal content in drainage water is studied under conventional agricultural management from 2013 to 2014 in two adjacent fields located in the North German Plain. Findings are compared with data of nutrients, main ions, and dissolved organic carbon, as well as element contents in fertilizers and geogenic background values of soils. Comparatively low metal concentrations are found in drainage water. These results are in line with metal contents of applied mineral fertilizers, of cattle slurry, and random analysis of the two soils considered. Relating to effective ordinances, the applied fertilizers occasionally pose a risk for the groundwater or downstream water bodies. Concentrations of some metals (Al, Co, Cr, Pb, and V) are rather affected by soil erosion than by fertilizers. Besides fertilizers and soil erosion, mainly pedo-hydrological conditions, which differ between the two fields, influence element profiles in tile drainage by the extent of anoxia and subsequent denitrification and sulfate reduction. Against the background of climate change, further investigations with respect to possible changes in soil water budget are necessary.

影响耕地排水中金属时空变异性的因素

在施肥方面，研究了 2013 年至 2014 年在常规农业管理下位于德国北部平原的两个相邻田地中排水中的金属含量。研究结果与养分、主要离子和溶解有机碳的数据以及肥料中的元素含量和土壤的地质背景值进行了比较。在排水中发现金属浓度相对较低。这些结果与施用的矿物肥料、牛粪的金属含量以及所考虑的两种土壤的随机分析一致。与有效法令有关，施用的肥料偶尔会对地下水或下游水体构成风险。某些金属（Al、Co、Cr、Pb 和 V）的浓度受土壤侵蚀的影响比受肥料的影响要大。除了肥料和土壤侵蚀，主要是土壤水文条件，这两个领域之间不同，通过缺氧程度和随后的反硝化和硫酸盐还原影响瓷砖排水中的元素分布。在气候变化的背景下，有必要进一步研究土壤水分收支可能发生的变化。
