A Method for Studying Infiltration1
- Helmut Kohnke2
A method for the studying of infiltration is described. The apparatus used consists of sixteen rectangular compartments, 10 cm. wide, 20 cm. long and 7.5 cm. deep, arranged in a block of four by four and of sixteen burettes. It can be easily transported and lends itself for work under a great variety of conditions.
The compartments are driven one to two inches into the ground and water is applied to each of them at the rate it is absorbed by the soil.
The average of the data obtained with the four center compartments is considered as a measure of the natural local infiltration, the outside compartments merely serve as a buffer between the center compartments and the relatively dry soil surrounding the experimental site.
The elimination of the buffer compartments results in data of greater variability. The superiority of the buffered method over the unbuffered method has not yet been shown conclusively.
