The agrarian trade of Slovakia has been marked with the increasing trend of negative balance in the last years. More unacceptable is the fact that it concerns replaceable commodities, namely the special economic group „cereals". The work analyses the Slovak foreign trade in this group in a period covering 1999 2001. For cereal growing, there are both appropriate natural conditions and sufficiently qualified human resources in Slovakia. However, agricultural primary producers are not yet capable of paralysing the adverse impact of weather, which was also reflected in the yield of cereal grain in 1999 and 2000. A low rate of constructed irrigation plants and particularly their exploitation as well as other intensification factors are among reasons why the negative balance of foreign trade in chosen commodities is being deepened. Managing unfavourable meteorological influences, a stronger approach of public authorities to sale_ support, protection from an excessive import of replaceable commodities, export support and other activities could contribute to d reduction in negative foreign balance of replaceable commodities in the foreign trade of Slovakia.
