Selenium (Se) is an essential nutrient. Surveys of Se status showed that Serbia is a low Se area. To increase the Se concentration, we supplemented Se to domestic animals and humans. The latest results showed that increasing Se content in domestic animals and humans induces a small increase in mean Se level. Exceptions were residents of urban, economically developed communities in which an increase in Se level were significant. The soil-plant system is the main natural source of Se for animals and humans. We used field treatments to raise the Se level in plants to the desired level. Foliar application of Se as Na2SeO3 was tested on cereals growing on different soil types. The influence of different growth factors on the uptake and distribution of Se in plants was tested and discussed. The foliar application of 6 g Se/ha is sufficient to raise the native Se content in whole wheat to levels of 42 to 67 microg/kg and in corn to levels of 19 to 36 microg/kg. The application of 12 g Se/ha is sufficient to raise Se levels in wheat to 65 to 180 microg/kg and in corn to 31 to 46 microg/kg.
硒（Se）是一种必需营养素。对硒状况的调查表明，塞尔维亚是一个低硒地区。为了提高硒浓度，我们对家畜和人类进行了硒补充。最新结果显示，家畜和人类体内硒含量的增加使平均硒水平略有上升。城市经济发达社区的居民是例外，其硒水平的上升较为显著。土壤 - 植物系统是动物和人类硒的主要天然来源。我们采用田间处理方法将植物中的硒水平提高到所需水平。在不同土壤类型上生长的谷物上测试了以亚硒酸钠（Na2SeO3）进行叶面施硒。测试并讨论了不同生长因素对植物中硒吸收和分布的影响。每公顷叶面喷施6克硒足以将全麦中的天然硒含量提高到42至67微克/千克，将玉米中的硒含量提高到19至36微克/千克。每公顷施用12克硒足以将小麦中的硒水平提高到65至180微克/千克，将玉米中的硒水平提高到31至46微克/千克。
