Gypsum for agricultural use is a byproduct of the phosphate fertilizer industry and broadly available in Brazil (Caires et al., 2011a). Gypsum is an excellent source of Ca (20 %) and S (1518 %); also, it supplies small amounts of P ( %).
Occurrence. Gypsum is a common, rockforming mineral, with thick, extensive beds formed by the evaporation of extremely saline waters. It is often associated with other minerals, such as halite and sulfur. It is deposited from lakes, seawater, hot springs, volcanic vapors, and sulfate solutions in geological veins. Hydrothermal anhydrite in ...
ABSTRACT The use of gypsum to improve the root environment in tropical soils in the southeastern and centralwestern regions of Brazil is a widespread practice with wellestablished recommendation criteria. However, only recently gypsum began to be used on subtropical soils in South of Brazil, so available knowledge of its effect on crop yield is incipient and mainly for soils under notill ...

gypsum, used in making plaster, as a soil amendment. On a prominent hillside, Franklin applied gypsum in a word pattern that read, "This land has been plastered." The increased grass growth in the area on which the gypsum had been applied served as an effective demonstration of its value as a fertilizer. Two hundred years later, gypsum
In Brazil, the Cerrado soils especially benefit from this use, primarily by the occurrence of Indian summer dry period during the rainy season, with days of intense heat and sunshine, with a minimum duration of 4 days (Agritempo, 2012). When applied to soil, the gypsum penetrates to below the topsoil layer, increasing the
Occurrence. Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.
Named in 1789 by Abraham Gottlieb Werner from the Greek word "kyanos", meaning "blue," the common color of the species. The French spelling, "Cyanite", was commonly used by mineralogists through much of the 19th and early 20th centuries.

The fact that black, gypsum crusts are able to develop over entire façades in a humid subtropical environment is testimony to the high levels of local pollution, especially particulate deposition. Reduced rainwash, in sheltered microenvironments of narrow, canyonlike streets, overcomes the gypsum tendencytobewashedawayfrombuildingsfaçades.
