Translocation of calcium into pea plants at different stages of dissolution of dolomite particles used for liming in a long-term field experiment

In a long-term (8 years) 10-year field experiment with alternating pea–mustard crops, changes in the pH_KCl were traced in sod-podzolic light loamy soil reclaimed by increasing doses of large (5–7 and 7–10 mm) dolomite particles. It has been shown that the higher the dose of dolomite, the greater the shift in soil pH. Differences in the pH_KCl value of the soil depending on the dose of dolomite application persisted throughout the entire observation period. Liming with dolomite particles had a positive effect on the accumulation of calcium by pea plants already in the year of application. Regardless of the variant, the calcium content in the green mass of peas decreased. Empirical models have been developed that describe the transfer of calcium to pea plants throughout the entire observation period. The average rate of calcium decrease in the soil during the experiment was determined. Clustering of individual experimental variants based on the effect of liming on the accumulation of calcium by plants was carried out.
