Soil Compactions & Hardpan

The ideal ratio for crop production should contain 25% water, 25% air and 50% soil particles.  The volume of water and air in the soil is referred to as pore space.  A reduction in pre space will result in increased soil density which causes poor internal drainage and reduced aeration.  This increased soil density directly affects crop yield. 

compaction Because of the smaller pores, soil compaction drastically reduces water infiltration.  This also results in fewer well-defined drainage channels.  This cycle sets up a long list of chain-event problems.  Compaction can be caused by heavy machinery weight, tire size, tire inflation and most importantly, soil moisture conditions.
