Chapter
This chapter is devoted to selenium and its role in organism. Selenium has been proved as an essential element for animals and humans. Perception of its role changed from the toxic toward essential element as in the last decade its importance has been described through its biochemical functions. Selenium can be found in the environmental components...
Chapter
The level of selenium in the human body depends on its concentration in food. Selenium enters the food chain primarily from soils, its content in plants is a function of the soil–plant system conditions. Analysis of selenium status suggests that fortification of the soil substrate with sodium selenate appears to be effective and undemanding form of...
Chapter
The risk of phytotoxicity and accumulation of selenium in the soil is significantly reduced by foliar application of selenium to photosynthetically active parts of plants. The use of foliar nutrition in practice has only expanded in recent decades, mainly due to the development of spraying techniques used in plant protection. Environmental factors...
Article
Selenium plays a significant role in preventing certain types of cancer and cardiovascular diseases. The level of Selenium in the human body depends on its concentration in food. In turn, the content in vegetable crops is a function of the soil-plant system. There are many countries in the world with low Selenium content in the soil. The average da...

Project
International Visegrad Fund Project Nr. 11530015 "Lesser-known species of vegetables, medicinal plants and edible mushrooms: new growing trends in context of V4 countries cooperation" is focused on the exchange of materials and information in the growing of medicinal and aromatic plants (MAPs) as well as lesser-known vegetables (including edible mushrooms). The output of partial project processes is creation of cultivar collection with medicinal and aromatic plants (MAPs), less-known vegetables and edible mushrooms, followed by a workshop – scientific seminar in the topic under professional guarantee of submitter and the project partners. Cultivar collection is interactively connected to the network by the help of QR codes; the web page will be serving besides scientific knowledge for propagation of the idea of economic and social cohesion of Visegrad countries. http://fzki.uniag.sk/lksvmpem/index.html
