Impacts of soil compaction
Witryna1 lut 1991 · At matric potentials near zero, soil compaction reduces soil hydraulic conductivity because it reduces the number of large pores. At matric potentials near- 1.0 to- 1.5 MPa, increases in soil compactness usually increase hydraulic conductivity because it in- creases particle to particle contact.
