The plastic limit of clays [PDF]

, 2013
The plastic limit of soils was first described by Atterberg in 1911. The thread-rolling test was standardised at the US Public Roads Bureau in the 1920s and 1930s, and has subsequently become one of the standard tests of soil mechanics.

Impacts of grass removal on wetting and actual water repellency in a sandy soil

Journal of Hydrology and Hydromechanics, 2017
Soil water content and actual water repellency were assessed for soil profiles at two sites in a bare and grasscovered plot of a sand pasture, to investigate the impact of the grass removal on both properties.
