In the years 2001-2003 an experiment on the 5 production plantations of winter triticale and 4 plantations of winter wheat was conducted. Variability of soil parameters (pHKCl, P2O5, K2O, MgO contents) and correlation relationships between soil characteristics and grain yield were studied. The content of phosphorus in soil ranged from 1.5 to 28.0 mg P2O5 100gE-1 soil among specified plots of winter triticale and 11.3-25.6 mg P2O5 100gE-1 soil among winter wheat ones; potassium 4.3-29.8 mg K2O 100 gE-1 soil (triticale) and 3.4-22.4 mg K2O 100gE-1 soil (wheat); magnesium MgO 3.2-13.6 mg MgO 100 gE-1 soil (triticale) and 3.1-14.4 mg MgO 100gE-1 soil (wheat). Acidity of analyzed fields expressed in pH ranged from 4.1 to 7.5 (triticale) and 4.5-6.9 (wheat). Variation coefficients for tested characteristics of soil on particular plantations varied from 20.0 to 49% (triticale) and from 17.0% to 34.0% (wheat) for potassium content and from 24.0 to 66.0% and from 10.0 to 19.0% for phosphorus, resp. while from 23.0 to 37.0% and from 16.0 to 28.0%, resp. for magnesium content. Soil acidity characterized with less variability in the fields and its variation coefficients varied from 8.0 to 12.0% for triticale plantations and from 5.0 to 11.0% for wheat.
