Chemicals that can be added to a new tank to force it to cycle within a much shorter period of time1/21/2024 ![]() In addition, the exchange of gases slows down in compacted soils, causing an increase in the likelihood of aeration-related problems. This happens because large pores more effectively move water downward through the soil than smaller pores. Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density.Ī compacted soil has a reduced rate of both water infiltration and drainage. Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). A well-structured soil holds and conducts the water, nutrients and air necessary for healthy plant root activity. Improving soil structure is the best defense against soil compaction. Heavy equipment and tillage implements amplify damage to the soil's structure, decreasing pore space and limiting soil and water volume even further. ![]() Wet soils are particularly susceptible to compaction. ![]() Soil compaction concerns have been growing in Minnesota as both annual precipitation and farm equipment size have dramatically increased. ![]()
