Irrigation of meadow-gray sandy loam soil was accompanied by the involvement of large amounts of alkaline and alkaline-earth metals in migration flows. The stock of mobile cations was very significant. According to their leaching capacity, they can be arranged in the following decreasing series: Na > Ca > Mg > K. the Average leaching rate for Ca and K was: $\user1{v}$ = –35.2, –3.98 mg/l, for Na and Mg: $\user1{v}$ = –16.1, –1.16 mg/l, respectively. As a result of repeated washing of the soil, it was not possible to achieve complete removal of water-soluble forms for any of the studied cations. Migration of iron is not established. The loss of fluorine from leaching by moisture was also significant. The average rate of losses during its migration was: $\user1{v}$ = –0.176 /l. A positive relationship between the content of fluorine and sodium, calcium, potassium and magnesium in filtrates was revealed of different strengths. Empirical models adequately describing the processes of migration of alkaline, alkalin
