Gypsum-exclusive plants accumulate more leaf S than non-exclusive species both in and off gypsum [PDF]
, 2021 Gypsum-exclusive species (gypsophiles), are restricted to gypseous soils in natural environments. However, it is unclear why gypsophiles display greater affinity to gyspeous soils than other soils.

Improvement of Gypseous Soil by Clinker Additive
Engineering and Technology Journal, 2010 In this paper, mechanical properties were studied for gypseous soilbrought up from Al-Axandria region, Babylon Governorate. Gypsumcontent is equal to (40%). Many tests were employed on disturbed andundisturbed samples collected at depth (1-1.5) m.Clinker material used in cement was chosen as additive to study itseffect on improvement of gypseous soil ...

Bearing Capacity of Bored Pile Model Constructed in Gypseous Soil
Journal of Engineering, 2015 Gypseous soils are distributed in many regions in the world including Iraq, which cover more than (31%) of the surface area of the country. Existence of these soils, always with high gypsum content, caused difficult problems to the buildings and ...

Despite phylogenetic effects, C3-C4 lineages bridge the ecological gap to C4 photosynthesis. [PDF]
, 2016 C4 photosynthesis is a physiological innovation involving several anatomical and biochemical components that emerged recurrently in flowering plants. This complex trait evolved via a series of physiological intermediates, broadly termed 'C3-C4', which ...

Influence of Leaching on Gypseous Soil
, 2014 Gypseous soil disturbed in many regions of the world. Existence of these soils with high gypsum content caused many problems to the buildings and structures that built on it due to dissolution and leaching of the gypsum slates by the action of water flow through the soil mass. Therefore, it is necessary to study the properties of such soils and improve
