Abstract Application of organic fertilizers may replenish soil organic matter, improve soil fertility and increase plant yield and its quality. This research deals with the effects of soil amendment with sewage sludge compost (SSC) on the chemical composition of plants (white mustard, triticale and white lupine) cultivated on two contrasting soils (light vs. medium). A 3-year pot experiment was conducted and SSC at the rate of 6 Mg ha−1 was applied to the soils.The study clearly demonstrated that SSC as an organic fertilizer had a minor influence on the modification of the chemical composition of shoots and grain cultivated in crop rotation plants and it was more evident in medium soil. The statistically confirmed effect was mainfested in higher c ontents of N and P in grain of plants in the 2nd and 3rd year of the experiment.

使用 MANOVA 评估在用污水污泥堆肥改良的两种不同土壤上种植的植物的化学成分

摘要 施用有机肥可补充土壤有机质，提高土壤肥力，提高植物产量和品质。本研究涉及使用污水污泥堆肥 (SSC) 进行土壤改良对在两种对比土壤（轻质与中质）上种植的植物（白芥菜、黑小麦和白羽扇豆）化学成分的影响。进行了为期 3 年的盆栽试验，将 SSC 以 6 Mg ha−1 的比例施用于土壤。该研究清楚地表明，作为有机肥料的 SSC 对芽和籽粒化学成分的改变影响较小在轮作植物中栽培，在中等土壤中更为明显。统计证实的效果主要表现在试验第2年和第3年植株籽粒中较高的N和P含量。
