... lettuce ( Lactuca sativa L.) grown in muck soils. Water fluxes in the root zone were modeled with HYDRUS-2D using measured soil properties and weather conditions. The model results showed that mean unsaturated hydraulic conductivity in the root zone was sufficient to meet transpiration demands down...

... differences with respect to As reactivity: an acid sand with minimal As retention capacity, a sandy loam with relatively high concentration of Fe/Al oxides, and an organic (muck) soil with high Fe/Al, Ca/Mg content with potential for higher As retention capacity. Our results show that soil properties had...

..., above which are (2) flat-lying spruce and larch logs and branches that date between ≈10 910 and 10 340 cal years BP. Above the woody materials are ≈55–75 cm of sand, interbedded with organic muck laminae, which we interpret as local alluvium. This stratigraphic sequence is overlain by muck soil...

... coef cients is unlikely to accurately characterize an entire VS pro le from a Delta site. For example, Figure 2 shows that the shallow peat, muck, and Holocene soils have larger gradients (i.e., dVS=dz) than the older Pleistocene soils at larger depths, with the transition occurring in the depth range...

.... Facts obtained from laboratory experiments help explain rock disintegration by frost action and also the movements of rock waste that result from the freezing of water-saturated soils. Bedrock gravels of stream valleys and coastal plains are buried under thick silt deposits, usually called “muck...

... (possibly as vegetation stabilized the soils ( Ballantyne 2002 )), causing the sharp difference from deposits above and below the unconformity. In the western Muck Deep (cores 731, 726 and 730) a massive diamicton followed by a laminated mud sequence, characterized by an arctic benthic fauna...

... ). In the Klondike area, these sediments primarily contain loess and are generally ice- and organic-rich ( Fraser and Burn 1997 ). The loess overlies auriferous creek gravels and is both colluviated and in primary depositional position. The sediments are locally called “muck” and are often exposed by mining. Two...

The samples collected are considered representative of ore and waste grade material being mined from the underground operations and consist of ‘skip’ and ‘muck’ samples that are sent to the assay lab on a daily basis...

The person was ignorant about the possibility of the development of pore water pressure in loose soil backfilled between the slope and the vertical wall due...

...’ of southern Skye, Eigg and Muck, formed in a similar depositional setting, although sandstones are not present. Alternations of carbonate rocks (some dolomitic) and calcareous shales probably reflect palaeoclimatic fluctuations between humid and arid periods. The overlying Skudiburgh Formation is interpreted...

In some instances, a combination of these procedures may be needed. The geomembrane liners can be installed with a soil or sod...

... father had worked on the Suez Canal, arrived in Panama to serve as chief engineer for construction.
