Boron sorption in soils and its extractability by soil tests (Mehlich 3, ammonium acetate and water extraction)

Popis výsledku v původním jazyce

The aim of the paper was to contribute to the acquisition of background data for the specification of safe boron levels in soils in relation to diagnostics by multi-nutrient soil tests and to CEC value of soil, pH and soil organic matter. Research was conducted on 24 soils. Sorption was determined after 97 days from the application of B rates (0; 1; 2.5; 5 mg B/kg in H3BO3). The closest regression of B-sorption was connected with the CEC value of soil in NH4-acetate and water tests and it increased withthe increasing application of B. (Regression at a rate of 5 ppm B; NH4-acetate: linear R2 = 0.632, polynomial 2nd R2 = 0.644; water: linear R2 = 0.644, polynomial 2nd R2 = 0.599). No relationship was found out in Mehlich 3 test. Regressions of B sorption on pH value were substantially lower. The relationship of B sorption with soil organic matter was similar to CEC, but of smaller closeness. In the NH4-acetate soil test, after the correction of CEC value of soil by pH deviations from th
