Abstract
Abstract Four methods were tested for suitability in collecting unaltered bulk (soil) solution from container root media. Suction methods led to higher cation and lower P concentrations as a result of interaction between the ceramic sampling cup and the bulk solution. Centrifugation methods yielded insufficient volumes of bulk solution thus calling for further refinements in procedures. Methanolic extraction resulted in lower concentrations of K, Ca and P. The lower concentrations were in accord with the lower dielectric constant for methanol compared to water; i.e., lower solubility and affinity of ions for the solvent. The column displacement procedure facilitated the collection of adequate quantities of unaltered bulk solution in a reasonable period (within 2 hours). A refined procedure is presented.
