The aim of this thesis is to reflect the current situation of using foliar nutrition of field crops and evaluate the consumption data of foliar-aplied nutrients. Monitoring of the use of foliar nutrition was carried out at the turn of the year 2015/2016 in 133 companies with plant production in the region Haná, specifically in districts Prostějov, Vyškov, Kroměříž, Olomouc and Přerov. Five main crops (winter wheat, spring barley, winter rape, corn and sugar beet), which cover approximately 85 % of arable soil in Haná, were the subject of the survey. The obtained data on the used preparations from individual companies were evaluated for individual districts and on the basis of corresponding acreage there was assessed the consumption of elements applied by foliar nutrition in a given area. More than 65 types of foliar-applied fertilizers were used in the monitored region. The most commonly used preparations for foliar nutrition are urea and bitter salt, next many of preparations from the serie Campofort made by AGRA GROUP a.s., which create total 54 % of all used foliar fertilizers in the monitored area. The highest average frequency of foliar nutrition inputs was registred in the rape (2,2) and the lowest in the corn (0,2). The consumption of individual macroelements in the monitored area was largest by nitrogen approx 1,2 kg/ha, next by sulfur 0,53 kg/ha, magnesium 0,36 kg/ha, potassium 0,1 kg/ha and phosphorus 0,06 kg/ha. For microelements, boron dominated in amount of 80 g/ha, next zinc 20 g /ha and manganese 11 g/ha. From the consumption results of foliar-aplied nutritions it is clear that the potential of using foliar fertilizers has not been fully applied yet.
