Agronomical effectiveness of liquid fertilizers which was compared with solid state in alluvial soil and illimerized soil has been studied. Test plants were as follows: winter wheat, spring barley, winter barley and winter rye. It was confirmed that the liquid fertilizers used to supplementary fertilization of winter wheat were efficient, when increase of the yield was 4.5 to 7.5 %. Higher yield in per cent was obtained by using liquid fertilizers. The results confirmed that the yield of spring barley increased from 6.9 to 9.4 % by using minimum two nutrients in liquid state. The protein content was not influenced. Concerning spring barley, two supplementary fertilizations in applications of liquid fertilizers in combination DAM 390 + nitrogen in nitrate has been studied. The highest effect in the yield has been found out with winter barley. Supplementary fertilization was compared once with the standard without supplementary fertilization for winter rye. The results showed the positive reaction in supplementary fertilization from 10.4 to 17.5 %, in solid as well as liquid state of nitrogen. The protein content increased by 5.8 % for winter rye.
