Arid Soils. Other than arid soil (belongs to Aridisol), three extra processes are prominent in subhumid and semiarid soils such as (1) pedoturbation or soil churning is responsible for the formation of Vertisol, (2) argillation or clay migration that forms Alfisol, and (3) melanization responsible for the formation of Mollisol (Kabata-Pendias, 2003;

2020-9-29 · Some soils, usually in semi-arid regions, suffer with very high concentration of salts and sodium, mostly due to high evaporation, low rainfall and lack of drain ability. Gypsum is used in these cases as a soil corrective agent, because it improves drainage, allowing the water to move into the soil and leach the excess minerals.

2021-2-9 · In arid and semi-arid areas gypsum is dissolved in the wet season and tends to be precipitated when the soil is dry. Whatever the source of calcium and sulphate ions, the precipitation of gypsum in soils is a function of the nature and the composition of the soil solution, as well as the effects of alternating wet and dry seasons.

Texture was determined with the pipette method but only for soils without 21 gypsum due to several problems with this procedure in soils with gypsum (Porta et al., 22 1986). Soils were classified according to Soil Taxonomy (SSS, 1999).

2020-5-4 · Mineral lime (calcium carbonate) in these soils can be converted to gypsum by adding sulfur, sulfuric acid, or other acidic or acid-forming materials (see Table 1 for equivalent quantities of various soil amendments). The acid dissolves the calcium carbonate, and the dissolved calcium forms gypsum.

Desert Soils

Desert soils may be gray-colored, brown, or even brick red. In the more arid parts of the Sonoran Desert, surfaces of some soils are covered by a layer of small stones that can be as tightly interlocked as pieces of an ancient Roman mosaic, and are coated with

GYPSUM IN AGRICULTURE: A BRIEF DISCUSSION

2020-7-7 · A soil which has ESP value greater than 15 is scarce even in semi-arid and arid condition while low ESP soil (ranging 1-5) is widespread in arid and semi-arid conditions and even humid regions (Shainberget al., 1989). As a result, the dispersive and unstable soils where gypsum potentially can be used are much more significant. The leaching

2021-2-22 · Salinity generally occurs in arid and semi-arid regions, where leaching of the profile is restricted (Bernstein 1975). Within Australia salinity affects 5.3% (386,300 km2) of the continent (Northcote and Skene 1972), although this area increases significantly if sodic soils that are also saline are taken into account. Soluble salts

THE SALT LAKE SYSTEMS AND THEIR ASSOCIATED

Dunes of both coarse crystalline and fine floury gypsum and lunettes of sand, silt, or clay size material are common near to the leeward margin of salt lakes. Further removed, materials, blown out from the lake areas as aggregates of clay, silt, and sand, are deposited as sheets which are medium‐textured and have a high lime content.
