Abstract The objective of the study was to compare the impact of three systems of multiannual fertilization applied in two long-term field experiments on the content of phenolic compounds in the soil. In the study, both natural (manure, slurry) and mineral (NPK) fertilizers were used, along with combined, organic-and-mineral fertilization. Experiment I was established in 1972 on grey brown podzolic soil; experiment II, in 1973 on brown soil. In both experiments crops were cultivated in a 7-year rotation, with a 75% share of cereals. The experimental samples were taken from the top layer of soil after 36 (experiment I) and 35 (experiment II) years following the establishment of the experiments. It was demonstrated that the presence of phenolic compounds in the soils was significantly dependent on the contents of organic C and total N, type of soil and the type and dose of used fertilizers. In grey brown podzolic soil, the content of total phenolic compounds was at a lower level than the content found in brown soil. Multiannual fertilization contributed to an increase in the content of total phenolic compounds in relation to the values obtained in control objects, which was particularly reflected in the soil originating from objects fertilized with slurry applied at a dose being equivalent to manure in terms of the amount of introduced organic carbon. The percentage of water-soluble phenols in the total content of these compounds in grey brown podzolic soil was at the level of 18.4%, while in brown soil it amounted to 29.1%.

两次长期施肥试验所得土壤中酚类化合物的含量

摘要 本研究的目的是在两个长期田间试验中比较三种多年施肥系统对土壤中酚类化合物含量的影响。在这项研究中，使用了天然（粪肥、泥浆）和矿物 (NPK) 肥料，以及有机和矿物相结合的施肥。实验一于 1972 年在灰褐色灰化土上建立；实验二，1973 年在棕色土壤上。在这两个实验中，作物以 7 年轮作种植，谷物占 75%。实验样品取自实验建立后36（实验I）和35（实验II）年后的土壤表层。结果表明，土壤中酚类化合物的存在显着依赖于有机碳和总氮的含量，土壤类型以及所用肥料的类型和剂量。在灰棕色灰土中，总酚类化合物的含量低于棕色土壤中的含量。与对照对象中获得的值相比，多年施肥有助于总酚类化合物的含量增加，这尤其体现在源自用浆液施肥的对象的土壤中，其施肥量相当于粪肥的量引入有机碳。灰褐色灰土中水溶性酚类占这些化合物总含量的百分比为18.4%，而在褐土中为29.1%。总酚类化合物的含量低于棕壤中的含量。与对照对象中获得的值相比，多年施肥有助于总酚类化合物的含量增加，这尤其体现在源自用浆液施肥的对象的土壤中，其施肥量相当于粪肥的量引入有机碳。灰褐色灰土中水溶性酚类占这些化合物总含量的百分比为18.4%，而在褐土中为29.1%。总酚类化合物的含量低于棕壤中的含量。与对照对象中获得的值相比，多年施肥有助于总酚类化合物的含量增加，这尤其体现在源自用浆液施肥的对象的土壤中，其施肥量相当于粪肥的量引入有机碳。灰褐色灰土中水溶性酚类占这些化合物总含量的百分比为18.4%，而在褐土中为29.1%。这尤其反映在源自用泥浆施肥的物体的土壤中，泥浆施用的剂量就引入的有机碳而言相当于粪肥。灰棕色灰土中水溶性酚类占这些化合物总含量的百分比为18.4%，而在棕壤中为29.1%。这尤其反映在源自用泥浆施肥的物体的土壤中，泥浆施用的剂量就引入的有机碳而言相当于粪肥。灰褐色灰土中水溶性酚类占这些化合物总含量的百分比为18.4%，而在褐土中为29.1%。
