Gypsum is a relatively common mineral that is widely available in agricultural areas and has a number of specialized agronomic uses principally as a Ca source on legumes and as a soil conditioner on sodic soils Recent research has suggest that the utility of

While accumulations of pedogenic gypsum commonly occur in alkaline environments gypsum has also been reported as an acid sulfate weathering product in mine spoils Doolittle et al 1993 Until recently descriptive terminology for gypsum soil morphology and soil taxonomic classification has been inadequate particularly for gypseous soils
The shortage of cultivated land resources in coastal areas of Zhejiang province can be effectively resolved by improving coastal saline alkali soil In this study the effects of different materials on salinization and fertility of coastal saline alkali soil in Zhejiang province were evaluated through column leaching experiment The results revealed that the soil pH were
Improvement of Saline Alkaline Soil via Flue Gas Desulfurization Gypsum and Safety Analysis of the Associated Heavy Metals Yanrong Fu Kun He Chunliang Zhou Yumei Mao He K Li XP Xu C Zhang ZG and Zhou CL 2018 Remediation efficiency of flue gas desulfurization gypsum on coastal saline alkali soil Res Environ Sci 31 547 554 in Chinese
Introduction Saline alkali soil in coastal China covers a large area and is widely distributed There are obstacles such as serious salinization low fertility poor structure and low and unstable crop yields Lv et al 2015 The Yellow River Delta with an area of approximately 5 × 10 5 hm 2 is a typical coastal saline alkali soil and a main resource of reserve land
Gypsum addition into saline∠alkali soil can elevate soil permeability by increasing ion concentration With the increase of gypsum proportion the significant decrease of EC and SAR in soil could be achieved [13] ZHAO et al [12] investigated the effect of gypsum addition on the saline∠alkali soil of Songnen plain and found that
This study results indicate that the optimal application amount for improving nutrients in saline alkali soil is t ha −1 of desulfurized gypsum and t ha −1 of organic fertilizer representing the TV treatment Effects of gypsum amendment and organic matter on soil enzyme activities in saline alkali soil
Adding gypsum to the soil reduces erosion by increasing the ability of soil to soak up water after precipitation thus reducing runoff Gypsum application also improves soil aeration and water percolation through the soil profile A recent study showed the benefit of gypsum application to improve movement of water through the profile to tile

Investigation of the effects of FGD gypsum addition on the soil properties and distribution profiles of the heavy metals in sodic soils revealed that heavy metal concentrations in soils complied well with Environmental Quality Standard for Soils in China GB15618 1995 gypsum could replace the natrium ions Na in alkali soil to cause its
The effective and safe use of FGD gypsum in agricultural land is still debated in some countries even though its effectiveness in soil management has been reported in many studies
For FGDG % of particle size is between and mm far smaller than that of natural gypsum Long et al 2017 which creates a better soil remediation effect than natural gypsum since small particle size can promote the reaction between gypsum and the main components of saline alkali soil Wang et al 2017a
Reclamation of saline sodic soils with gypsum from the desulphurization of flue gas FGD is a recently developed technique However limited information is available on the long‐term effects of FGD gypsum in agricultural fields This study evaluated the effects of FGD gypsum on soil physical and chemical properties and heavy metal concentrations after 17
Salt and sodicity of saline alkali soil adversely affect the construction of ecological landscapes and negatively impact crop production The reclamation potential of biochar BC wheat straw biochar applied at 1% by weight gypsum G % by weight and gypsum coupled with biochar GBC was examined in this laboratory based study by evaluating their
Zhang et al 2020b investigated the influence of biochar combined with gypsum on saline alkali soil in soil column experiments reporting that biochar application significantly increased the
As one of the three largest sodic saline alkali soil distribution regions in the world the Songnen Plain of Northeast China contains > million ha of land estimated to be affected by sodicity Wang et al 2009 The parent materials topographical features climatic conditions and anthropogenic factors there contribute to the formation and evolution of the salinization of
Lime and gypsum are common soil amendments and many homeowners tend to get confused about what each does for turfgrass and the lawn issues each amendment addresses Each product can be great for lawns Conversely if your soil is alkaline you shouldn t spread any lime instead your lawn might benefit from an application of Sulphur to
Benefits of Alkaline Soil While some plants thrive in acidic soil others require alkaline soil to grow and produce healthy yields Alkaline soil can provide several benefits to plants including Better absorption of nutrients Alkaline soil can help to increase the availability of essential nutrients such as phosphorus potassium and calcium
The main environmental limitation in arid and semiarid area of the world for agricultural productivity and sustainability which degrades soil is salinity and/or sodicity Pitman and Läuchli 2002; Qadir et al 2006; Suarez 2001; Tanji 1990 In salt affected soils there is higher concentration of soluble salts salinity and/or Na in the solution phase as well as on cation
Flue gas desulfurization simplified as FGD gypsum a kind of byproduct from wet FGD process of coal fired power plants was used to ameliorate saline alkali soil The FGD gypsum can react with
