The investigation had the objective to evaluate the applicability of ion-exchange substrate to maintaining the mobile nitrogen content in irrigation solution and artificial coil during cultivation of a mixed (in term of age) vegetable container. Objects of the investigation were radishes and leaf cabbage crops with the period of vegetation of 28 days. A 120-day experiment showed that single introduction of the ion-exchange substrate promoted nitrogen stabilization in the irrigation solution and, consequently, yielding of higher crops as compared with the control.
