Most commonly cultivated cruciferous vegetables in Poland are cabbage (white-headed cabbage, red-headed cabbage, napa cabbage), Brussels sprouts, cauliflower, broccoli and kale.
Cruciferae requires rich soil nutrient status and soil acidity (N-240 270kg/ha, P-120-140kg/ha, K-360-420kg/ha in a pure component). The soil pH for these crops shall be of the 6.5-7.5 level.
In response to clubroot, one of the most dangerous diseases in cruciferae production, which develops rapidly in acidic environments, soils on which cruciferae are cultivated require treatment with lime, which should be carried out after a soil analysis. In order to increase soil pH, highly reactive oxide lime or carbonate lime shall be used (it has a slower reaction period and hence, is effective for a longer time). Lignohumat super, which contains humus-acids, and bacterial preparation bi protect is also suitable in preventive measures regarding clubroot.
