PDF-How Compaction Affects Tree Root Growth and Structure

Noncompacted soils ar e actually about 50 pore space These pores range in size from small micropor es that hold and release water between rainfall events and large macropores from wh ich water drains rapidly after a rainstorm Soil macropores are imp.

Compaction occurs when a force compresses the soil and pushes air and water out of it so that it becomes more dense. Compaction is more severe when the soil is wet and less able to withstand compression.. Topic. COMPACTION. Presented to . Dr. . Ayub. . Elahi. Presented by Group leader.. .
