Soil Penetrometer, measure compaction and hardpan

KNOW your soil well. and treat it, then you plant your crops.  We might well understand that soil compaction determine so many aspects of agronomic decisions. Hard and compacted soil lead to higher costs for crop production. Soil penetrometer  is very useful for the farmers to determine the soil compaction levels. 
This instrument 'reads' soil compaction by measuring the soil resistance and features a stainless steel rod with depth marks of 3,6,9,12,15 and 18inches. Analog gauge reacts to pressure applied to cone while penetrating soil. If you are able to diagnose that you have a compacted soils problem using a penetrometer, then you can take measures to fix the problem by loosening and aerating your soil.
