The studies carried out in 124 productive hop gardens showed a distinctly varied soil reaction - pH in 1 mol KC1 dm⁻³ from 4.0 to 7.3. Correlation coefficients as well as the calculated regression coefficients at 2° between the pH values and hop crops in individual hop plantations proved to be insignificant. On the plantations with higher soil pH a significant increase in the contents of Mg, Ca, and...
