Measurement and interpretation of physical properties of soils

Creator:

Nagpal, Narender Kumar, 1942-

Presently the pore size distributions of soils are most commonly obtained from soil water characteristic curves. The soil water characteristic curves are usually obtained by the pressure plate technique. It...
