Abstract
A technique is described whereby fertilizer, equivalent on an area basis to that applied in a band, diffuses into a soil-filled column of stacked rings. By recovering individual rings, 5 mm sections of soil are obtained at different distances from the fertilizer source. These soil sections are enclosed in an assembly which allows short term (48 h) root growth experiments to be undertaken. Following these experiments, sufficient soil solution can be extracted from each soil section to enable multi-element analyses.
