Effect of mineral amendment on the gypsum and salinity .
· Gypsum soil can be defined as soil with less than 40% gypsum (CaSO 4 .2H 2 O), and gypsiferous soils have gypsum contents of between 1 and 40% (Pearson et al. 2015 ). It has proven difficult to establish the global distributions of soils with particular contents of gypsum.

Using Visible and near Infrared Spectroscopy to Estimate .
· Carbonates and gypsum in a total of 251 sieved and airdried topsoil samples from Isfahan Province in central Iran were measured by standard laboratory methods and visNIR spectroscopy (350–2500 nm wavelength range). In parallel, PLSR and the feature specific method based on CR spectra were used to predict carbonates and gypsum.
How does gypsum improve soil structure?
Why is gypsum added to soil? Gypsum is added to bring down the pH of soil, if it is found to be greater than Soil having pH > is called sodic soil or alkali soil. It causes the problem of water logging in soil. High water content of soil may harm some crops that require lesser irrigation. Gypsum is added to soil to reclaim such soils.
gypsum
Gypsum is a nonmetallic mineral, found in rock form. It is composed of % calcium sulphate and % water, by weight. Chemists call it Hydrous Calcium Sulphate, and as there is one molecule of calcium sulphate combined with two molecules of water. It has the chemical formula CaSO 4 2H 2 0.

The solubilities and dissolution rates of 3 gypsum sources [analytical grade reagent (AR), phosphogypsum (PG), mined gypsum (MG)] with 6 MG size fractions (>, –, –, –, –, < mm) were investigated in tripledeionised water (TDI) and seawater to examine their suitability for bauxite residue amelioration. Gypsum solubility was greater in .
Agricultural Gypsum
GYPSOIL® is a brand of agricultural gypsum that will sure to yield better crops and a more profitable harvest. Not only that, agricultural gypsum also prevents water runoff, protecting the soil from unnecessary water runoff from particularly big storms which create erosion. Agricultural gypsum also significantly reduces the salinity of the soil.

Band appliion of flue gas desulfurization gypsum improves sodic soil ...
· In soil bin 1, a trench with a width of 6 cm and a depth of 5 cm was dug on one side 10 cm from the left edge. After adding 360 g FGD gypsum, the trench was covered with sodic soil; this system acted as a singleband treatment. In soil bin 2, two trenches with a width of 4 cm and a depth of 5 cm were dug on two sides, both 10 cm from the edge.
Mining
Gypsum Gypsum occurs in the Port Royal Mountains of eastern St. Andrew where it is mined by quarrying. It is used in Jamaica as a retarder for cement. It is ground with cement in the proportion of approximately 1 part to 20 parts of cement. Another use is in the manufacture of plaster of Paris, which is used to make ceiling tiles and plaster.
Clearing Pond Water With Gypsum
· Gypsum, or calcium sulfate (CaSO4), is a natural, watersoluble mineral that often occurs in sedimentary rock systems. Considered the most common of sulfate minerals, it is deposited by saltwater, lakes, volcanic vapor, and hot springs. It forms when sulfuric acid comes into contact with calcium carbonate.
Soil moisture sensors for agriculture
· renkeer_admin. Soil moisture sensors are also known as soil moisture meters. It is mainly used for measuring soil volumetric water content, monitoring soil moisture, agricultural irrigation, and forestry protection. The soil moisture sensor commonly used at present has FDR type and TDR type, namely frequency domain type, and timedomain type.
