The Auger has been found to be an effective and economical alternative to the digging of profile pits in order to examine and describe soil profiles as part of any soil mapping exercise.
Procedure - Get the most from your Auger
Certain requirements need to be observed for the efficient use of this handy tool.
In the first place, large numbers of boudlers and stones (larger than 25 to 30mm in diameter for example) will prelude the use of an auger and it has to be accepted that the pick and shovel will have to come out! Secondly a disciplined and methodical procedure as outlined below will make it possible to describe practically all important pedological characteristics of the soil profile. Some argonomic information, notably root development and distribution, cannot be observed easily and profile pits are more satisfactory.
The 100mm bucket Auger has been found to be the most effective, it penetrates all soil types easier than the 75mm and produces larger clods to examine, for example to assess permeability and structure. The shaft should be marked off in convenient depths (commonly 30 - 60 - 90mm from the bottom to the bottom of the Auger bit). Finally, the 70cm handle has obvious advantages in leverage when conditions are difficult.
