文摘
- •
Volume of pores >0.5 mm in size decreased within one month after harrowing.
- •
This reduced field-saturated hydraulic conductivity, but not laboratory measured Ks.
- •
Sample-scale connectivity of pores large than 0.5 mm in diameter was always limited.
- •
Ks was correlated with imaged porosity <0.5 mm in size and global pore connectivity.
