The objective of the work was to determine the effect of undersown catch crops, which were either autumn-incorporated or left on the soil surface as mulch for spring incorporation, on the microelement content in the tubers of potato cultivated in the integrated and organic production system. Field research was conducted at the Zawady Experimental Farm owned by Siedlce University of Natural Sciences and Humanities, Poland (52° 03' 39″ N, 22° 33' 80″ E). The following two factors were examined in the study: (i) organic fertilisation, control, farmyard manure, serradella, westerwolds ryegrass, serradella applied as mulch and westerwolds ryegrass applied as mulch and (ii) production system, organic and integrated. Microelements (B, Cu, Fe, Mn, Zn) were determined in potato tubers samples. The tubers of potato manured with autumn-incorporated serradella had the highest iron and zinc contents, whereas tubers following autumn-incorporated serradella and spring-incorporated serradella mulch had the highest boron content. Manuring with undersown catch crops and farmyard manure contributed to a decline in the potato tuber content of copper and manganese. Potato cultivated in the integrated production system contained more copper, manganese and zinc, whereas organic tubers had more iron and boron.
本研究的目的是确定作为绿肥秋播或留在地表春季翻耕的间作作物对在综合和有机生产体系中种植的马铃薯块茎中微量元素含量的影响。该田间试验在波兰 Siedlce 大学自然科学与人文学系的 Zawady 实验农场进行（52°03'39″N，22°33'80″E）。研究考察了两个因素：（i）有机施肥，对照，农家肥，紫花苜蓿，威尔斯小麦，紫花苜蓿作为覆盖物，威尔斯小麦作为覆盖物；（ii）生产体系，有机和综合。在马铃薯块茎样本中测定了微量元素（B、Cu、Fe、Mn、Zn）。秋播紫花苜蓿施肥的马铃薯块茎铁和锌含量最高，而秋播紫花苜蓿和春播紫花苜蓿覆盖物施肥的马铃薯块茎硼含量最高。间作绿肥和农家肥施肥导致马铃薯块茎铜和锰含量下降。在综合生产体系中种植的马铃薯含有更多的铜、锰和锌，而有机马铃薯含有更多的铁和硼。
