May 1, 2011 · Since these soils were somewhat excessively or well drained, the bedrock serves to temporarily restrict internal drainage to increase the time for soil particles to react with the soil solution. Eight of the soils are developed under excessively to well-drained conditions in relatively uniform sandy outwash, and yet they contain ortstein.

Jan 1, 2014 · Properties: Ortstein is 25 mm or more thick and 50% or more (by volume) cemented (Soil Survey Staff, 1999). As a rule, the horizon has sandy grain-size distribution. Compared to the adjacent non-cemented horizons, ortstein usually has a higher bulk density (Lambert and Hole, 1971; Wang et al., 1978). It is also stronger; the penetration ...

Pyrophosphate index Place 1g of sodium pyrophosphate in a small plastic, screw-topped container, add 4 ml of water and stir. With a syringe measure a 5 cm3 sample of moist organic material as in method 2.81 and place it in the plastic container, stir, and let stand overnight. Mix the sample thoroughly the next day.

where ortstein eventually forms than in those where it is absent. However, ortstein is not restricted to soils with poor drainage as only 39% of the soils with ortstein have an aquic soil moisture regime. From a weight-of-evidence assessment, ortstein is cemented by Al-organic complexes and short-range-order compounds, and placic horizons
Jan 1, 2022 · It is worth noting that the abundant root system of perennial grass species may result in a large proportion of the rhizosphere soil or even form exclusively rhizosphere soil in the topsoil that may further increase soil water repellency (Lipiec and Gliński, 2011). As to the deeper ortstein Bhsm and Bfe horizons, the higher level of soil water repellency under FH than GD can result from the ...

Ortstein horizons at two sites in the Maritime Provinces were found to be strongly developed and continuous in poorly drained locations in the observation trenches, and intermittent at well drained locations. Roots did not penetrate the ortstein horizons but most ortstein clods were permeable to water, with saturated hydraulic conductivities ranging from about 0.1 to 31 cm/h. The unconfined ...
