Lack of a suitably simple technique to study the fate of nutrients applied to soil columns of given bulk density and water-table exposure prompted the development of the apparatus described here. The system has a split pipe, containing the soil column, housed in an outer jacket. Peat or mineral soil can be packed into the split pipe to pre-selected bulk density values which vary little with depth. The split pipe/outer jacket assembly can be subjected to various water-table treatments according to the position of a drainage outlet in the associated water jacket, and drainage water from the assembly can be collected via the drainage outlet. Undisturbed soil samples are obtained after removing the split pipe from its jacket and breaking its watertight seal. The apparatus is economically constructed and may be used for a variety of experimental objectives.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
