- Scope
- This document specifies a method for the determination of the lime requirement of acid soils to target pH levels at requested time of maintenance as determined by reaction with 0@1 mol/l ammonium acetate pH 5@5. Due to general soil buffering systems@ the method is applicable to all soils which are acid enough to dissociate hydrogen ions from the soil colloid system to depress the pH of the buffer solution. NOTE 1 The method originates from research in Canada and Norway@ see [1] and [2]. NOTE 2 Annex A gives regression equations to predict the maintenance of a range of pH levels at different times after liming in mineral and organic soils in Europe.
