Stabilization of Gypsum Clay Soil by Adding Lime. Often, the temperature and water variation exist in semi-arid areas of a clayey soil leads to vertical and horizontal settlements, cracks in the soil and in general disorder to the building installed on this soil. The objective of this work is to stabilize the local gypsum clay soil, which poses ...
Along with reclaiming sodic 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.

Iberian semi-arid gypsum environment. This has been carried out by means of Canonical Correspondence Analysis as a hypothesis-testing tool. CCA models show that the spatial data matrix is able to explain a relevant fraction of the soil data set (P < 0.001). The most important variable, as firstly selected in the CCA stepwise selection
Plant species growing on gypsum substrates, usually found in arid and semi-arid zones, create characteristic landscapes that can harbor highly specialized species, several of which are endemic. In the Cuatro Ciénegas basin (CCB) gypsum is abundant and creates patches of plant assemblages, but little is known about the floristic …
This paper determines the influence of lime and gypsum on the rehabilitation of a degraded sodic soil in a semi-arid environment 12 years after application. ... many semi-arid landscapes in ...
At present gypsum helps to mitigate the adverse effect of climate change from humid to semi-arid during the Holocene. The present sustainability of crop productivity in such soils would however be further improved by using good-quality irrigation water as gypsum (Fig. 5.4c ) has been available for the last several thousands of years (Pal et al ...
This paper determines the influence of lime and gypsum on the rehabilitation of a degraded sodic soil in a semi-arid environment 12 years after application. The aim was to assess rehabilitation strategies for sodic soils as alternatives to the application of gypsum alone. An experimental site was used where lime and gypsum …
Gypseous (high-gypsum) soils generally occupy sparsely populated land with minimal land use intensity in arid and semiarid climates. Gypsum content in …
Lime and gypsum are valuable soil amendments in certain areas of the United States. Many s is often …
In present investigations locally available lime and gypsum of commercial grade has been used for studying the effect of lime and gypsum mixture on the plasticity and swelling properties of ...
As occurs in other arid and semi-arid systems, depositional sites of basal zones, which receive runon water, support grasses (Stein and Ludwig, 1979; Wondzell and Ludwig, 1995) like Lygeum spartum L. tussocks inour case. In contrast, steeper slopes which 145 Figure 1. Biplots from the three significant CCA models of the soil data set.
For instance, gypsum (CaSO₄) contains Ca in appreciable amounts, but does not reduce soil acidity. ... HYDRATED LIME. Hydrated lime (Ca (OH)²) is calcium hydroxide, sometimes called slaked or builder's lime. ... Many soils in the semi-arid and arid regions of the United States have a naturally high pH. They may contain significant ...

Results show that the abundance of mosses and lichens forming biological soil crusts was related to a limited set of variables, and provide some insights into the importance of these variables as drivers of biological soil-crust composition and abundance in semi-arid gypsum environments. Despite important advances in the understanding …
Results indicate using lime and gypsum singly, or in combination, at low agronomic rates is not necessarily viable for broadacre-irrigated-agriculture on alkaline clayey soils. ... This paper determines the influence of lime and gypsum on the rehabilitation of a degraded sodic soil in a semi-arid environment 12 years after …
The effects of adding three percentages of gypsum (2%, 4%, and 8%) to 6% lime-stabilized expansive soil to improve its engineering properties are investigated through several …
In this paper, we examine the effects of surface-applied lime and gypsum on soil profile chemical properties that affect Al toxicity in short-term (1 year), medium-term (2 years and 8 months) and long-term (10 years) …
study has evaluated such relationships in semi-arid gypsum areas. As observed in other semi-arid areas (Eldridge 1996, 1999; Eldridge and Tozer 1996, 1997), we hypothesised that subsurface soil attributes would exert a significant influence on biological-crust abundance at small spatial scales, and that this fraction of variation would not be
This work compares the effect of three increasing grazing intensities (low, medium, and high) on the hydraulic properties of the upper soil layers, measured on two areas with increasing gypsum content (56 and 73%, respectively) located in a semi-arid region of the Middle Ebro Valley (NE, Spain). 90 soil samplings were taken on bare soil …
Addition of gypsum to soil can limit clay swelling and dispersion, and thus improve soil structural stability, by both soil solution electrolyte effects and cation …
Gypsophily, i.e. the relationship between plants and gypsum soils, has been extensively studied only in arid and semi-arid regions, in contrast to tropical areas, where gypsum outcrops act as ...
Gypsum is commonly applied as an ameliorant but there are few field studies into its long-term (> 10 years) effects on soil chemistry, especially at depths greater than …
Areas: They occur in arid and semi-arid regions, and in waterlogged and swampy areas. These are more widespread in western Gujarat, deltas of the eastern coast and in Sunderban areas of West Bengal. ... These soils can be reclaimed by improving drainage, by applying gypsum and/or lime, and by cultivating salt resistant crops like …
Soil salinization and sodication pose significant environmental challenges, especially in arid and semi-arid regions, causing land degradation.
The aim of this paper is to evaluate seed bank density and composition along a semi-arid gypsum gradient in Central Spain. Seed bank density was relatively high (16,214 seed/m(2)) with a very ...
Anhydrite (CaSO 4) and gypsum (CaSO 4 ·2H 2 O) are the two most abundant minerals of ancient marine evaporite deposits and are also common in non-marine evaporite deposits. Sedimentary gypsum forms by direct precipitation out of evaporating seawater under arid climatic conditions in hydrologically restricted marine …
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 semi-arid-type climate; (2) several phytocoenological and soil parameters show a comparatively rapid recovery trend in the values of unaltered lands, but this pattern is …
