· Gypsum is an abundant soil mineral in arid and semiarid climates with low rainfall and gypsiferous parent material. Although gypsum is found over a .
Gypsum is calcium sulfate dihydrate (CaSO 4 2H 2 0). Flue gas desulfurization (FGD) gypsum, such as GYPSOIL ® brand gypsum, is a coproduct material derived from the scrubbing of flue gas emissions in coalburning power plants. Gypsum can be spread with lime and litter spreaders. Gypsum is not acid soluble and will not change the soil pH.
soils; the other most common utilities of gypsum are reducing soil crusting in arid and semi areas where it can increase infiltration rate despite scarce rainfall and improving seed germination. In high aluminium rich soil, gypsum can suppress the Al ions from damaging the root system by replacing it with Ca ions thus helps to establish a sound root system (Ritchey et al., 1995). On the ...
These findings provide information for evaluating land use practices for increased soil carbon sequestration under semiarid region biofuel crop production. This study investigated a new strategy for increasing carbon retention in slightly alkaline soils through addition of fuel gas desulfurization gypsum (FGDG, CaSO4∙2H2O).
Smallscale spatial soilplant relationship in semiarid gypsum environments Adrián Escudero IntroductionIt has been long accepted that interactive soilplant relationships induce spatial patterning in soil properties, and that individual plant performance and even plant communities may respond to soil heterogeneity caused * FAX No: +.

· Gypsum rich soils are found in many parts of the world, particularly in arid and semiarid regions. Most gypsum occurs in the form of evaporites, which are minerals that precipitate out of water due to a high rate of evaporation and a high mineral concentration. Gypsum rich soils make good foundation material under dry conditions but pose major engineering hazards when exposed to water.
Lime • Accummulation of ... SemiArid soils of Central Otago and identifying characters of the wines grown on those soils. There is also a logical expectation that individual vineyard wines may have characters that are the expression of the soils the vines are grown on. But to identify subregional wine characters within the SemiArid soil zone of Central Otago and be able to relate those to ...

In the present work, successional plant and soil dynamics on abandoned gypsum quarries were studied, using the chronosequences approach covering a time span of 70 years. From an ecological perspective, the results suggest that: (1) the successional pattern on gypsum outcrops does not differ greatly from that observed in other areas under semiaridtype climate; (2) several phytocoenological ...
Sodic soils tend to be in semiarid regions of the world. Decreases pH of sodic soils: The sodic soils are characterised by the high soil pH (>). Gypsum lowers the high pH of sodic soils or near sodic soils to to These values are in the range of acceptability for growth of most crop plants. Increased calcium uptake by roots when gypsum is applied can decrease the pH of the ...
· Gypsum is commonly used to reclaim sodic and saline soils in arid and semiarid regions, for example, especially where salty water is used for irrigation. Gypsum has also been shown to increase aggregation, reduce surface crusting, improve crop rooting, and boost yields in soils of the Southeast's Piedmont and Coastal Plain regions. There the ...
Why are arid/semiarid zone soils salty, and why does it matter? First, let us answer why soils get salty. Salts are naturally occurring, soluble minerals in areas where soil evaporation and plant water use (or transpiration) are both high, and precipitation is low. In that scenario, dissolved minerals concentrate over time as the extraction of essentially pure water leaves the soluble mineral ...
Resilience of the semiarid tropical soils T ... Over time these powdery lime particles accumulate to form lime concretions (conca). The depth function of PC shows 12an increasing trend . On many occasions the surface soils (0–25 cm depth) may be devoid of CaCO 3 but the subsurface indies its richness. The depth function of CaCO 3 is related to MAR 8 and are designated as concas called ...
In arid and semiarid 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. Gypsum can be transformed into anhydrite upon heating ...
· Lime and gypsum are valuable soil amendments in certain areas of the United States. Many s is often unnecessary.
When this technique was applied in arid climates it was noticed that on occasion lime treatment induced very severe swelling. This apparently anomalous behavior was traced to the presence of watersoluble sulfate in the treated soils. The sulfate in gypsum, for example, reacts with the lime and clay mineral breakdown products to produce a mineral from the ettingitethaumasite solid solution ...
In heavy textured clay soils in semiarid regions, many parts of inland Australia, sulfur may be low in the topsoil, but gypsum accretions may be present at depth (in the subsoil). A small amount of starter sulfur is all that is required in these circumstances, to satisfy plant demands in the seedling stages until such time that the crop roots have reached the subsoil. In these ...

· Some soils, usually in semiarid 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.
