Abstract
The base-neutralizing capacity (BNC) is an important property to characterize acid soils. The BNC can be reliably determined by soilbase titrations (BNC tit). But these methods are work-expensive, and a large amount of soil material is needed. Such a large amount of soil material is not available if the soil is sampled by a hand-auger (e.g. mapping, areal investigations). Known buffer methods require less soil material, but have some shortcomings. Therefore, the well known Schachtschabel-method with calcium acetate buffer was developed for the application to strongly acidified soils. BNC values measured by the developed calcium acetate method (BNC ac) agreed nearly perfectly with BNC tit values of 59 mineral soils. The BNC ac slightly overestimated (< 10%) the BNC tit of 10 samples of humus layers. Furthermore, small soil samples (down to 1 g soil), wide soil:solution ratios, and integration of pH (H 2O) measurements into the determination of the BNC ac yielded reliable BNC ac values. Thus, the BNC ac-method may be recommended as a simple and reliable method to determine the BNC of acid soils, especially if only a small amount of soil material is available.
