Examples of Surface soil in a sentence

  • Surface soil samples will be collected from within the top 12 inches of the subsurface after coring through existing pavement or ground cover.

  • Surface soil moisture was monitored using a set of impedance moisture sensors Delta-T Theta Probe ML2 (mention of manufacturers is for the convenience of the reader only and implies no endorsement on the part of the authors).

  • Surface soil moisture was calculated between 0 to 1 cm (Θ0–1 cm), 0 to 2 cm (Θ0–2 cm), 0 to 3 cm (Θ0–3 cm) and 0 to5 cm (Θ0–5 cm) deep and could be computed at any depth down to 90 cm.

  • Surface soil textures are loams and sandy loams except for the Lincoln Bench site, which is silt loam probably of eolian origin.

  • Surface soil thickness is the average thickness of the surface soil for use in estimation of the leach rate constant.

  • Surface soil cover would be mined and stockpiled separately to be placed over the areas of backfilled pits as part of progressive rehabilitation.At closure, the surface topography would be similar to the pre-mining landscape.In a method already assessed (EPA Assessment 1819 and EPBC 2009/5174) for mining at Centipede, the mined out voids at Millipede would be used for tailings storage.

  • Surface soil pHw was generally low (Table 1) but not universally so.

  • Surface soil moisture was estimated either manually (by weighing samples collected in the field) or automatically (in situ capacitive measurements).In 1995, soil moisture profiles within the top 5-cm soil layer were measured manually, twice a day, during two 30-day intensive observing periods (IOPs) in spring and autumn: 1-from DoY 114 to 143 for the spring-IOP, 2- from DoY 2б9 to 298 for the autumn-IOP.

  • Surface soil samples will be collected using a stainless steel hand trowel.

  • Surface soil moisture content is the volume fraction of the soil that is moisture.Total infiltration rate may be evaluated as the total annual precipitation + irrigation rate - evapotranspiration rate.
