Soil Compaction can be cause by many sources. Farming equipment, such as trucks and tractors, can lead to fragipan. Earth moving equipment can also cause compaction. Pastures can even be compacted by animals when field are wet (McMahon 147). That means even lawn mowers and people can cause compaction in their own lawn & garden. Especially when the soil is wet. These compacted soils have a higher Bulk Density. As the Bulk Density goes up, the pore space goes down.

Pore space is a needed part in the growth of any plant; grass, roses, corn, tomatoes, flowers. Remember, Field Capacity is the point where there is an equal amount or distribution of water and air in the soil profile. Plants need both air and water to survive. Compacted soils do not allow water, air or roots to penetrate easily. Water, air and roots are necessary for a healthy enviroment to grow plants and sustain the ecosystem for other organisms (Utah.gov).
