The DICKEY-john Soil Compaction Tester is a penetrometer that measures the firmness (compaction) of soil. The instrument has two tips: 1/2” tip for use in firm soil and 3/4” tip for use in soft soil. The dial indicator has two scales (for 1/2” tip and 3/4” tip) that are calibrated in pounds per square inch of the base area of the cone (tip) and are color coded for reference only. The colors are green (0-200 psi), yellow (200-300 psi), and red (300 psi and above) where most crop roots can grow well in the green range, fair in the yellow range, and poor in the red range.
The best time to use the tester is early Spring when the soil has good moisture content. Moisture content and soil texture effects readings. For this reason, the soil compaction tester is best used to compare the readings of the same soil type and moisture content. Check a fence row and then check the field area for comparison. It is advisable to do several tests in an area to get accurate readings.
The soil compaction tester usage:
– before tilling to verify if there is a compaction layer
– to identify how deep the compaction layer is
– to identify how deep the soil is actually worked
– if the tillage operation solved the problem.
