The most common is the heptahydrate MgSO4\u00b77H2O, known as Epsom salt, which is a household chemical with many traditional uses, including bath salts.<\/span><\/p>\n<p class=\"MsoNormal\" style=\"text-indent: 24.0000pt; mso-char-indent-count: 2.0000; text-autospace: ideograph-numeric; mso-pagination: none; line-height: 125%;\"><span style=\"mso-spacerun: 'yes'; font-family: Georgia; mso-fareast-font-family: \u5b8b\u4f53; line-height: 125%; font-size: 12.0000pt; mso-font-kerning: 1.0000pt;\">The main use of magnesium sulfate is in agriculture, to correct soils deficient in magnesium (an essential plant nutrient because of the role of magnesium in chlorophyll and photosynthesis). The monohydrate is favored for this use; by the mid 1970s, its production was 2.3 million tons per year. The anhydrous form and several hydrates occur in nature as minerals, and the salt is a significant component of the water from some springs.<\/span><\/p>\n<p class=\"MsoNormal\" style=\"margin-left: 21.2500pt;

It is most commonly used for potted plants, or magnesium-demanding crops such as potatoes, tomatoes, carrots, peppers, lemons and roses. The advantage of magnesium sulphate over other magnesium-containing soil amendments, such as calcium dolomite, is its high solubility, making it an option for foliar application as well. The pH of magnesium sulphate solutions is close to neutral compared to the slightly alkaline magnesium salts found in limestone; therefore, the use of magnesium sulphate as a source of magnesium in the soil will not significantly alter the pH of the soil. Magnesium sulphate controls pests and slugs, helps seeds germinate, produces more flowers, improves nutrient uptake, and is environmentally friendly, but contrary to popular belief, magnesium sulphate does not have any effect other than correcting magnesium deficiencies in the soil.<\/span><\/p>\n<p class=\"MsoNormal\" style=\"text-indent: 24.0000pt; mso-char-indent-count: 2.0000; text-autospace: ideograph-numeric; mso-pagination: none; text-align: justify; text-justify: inter-ideograph; line-height: 125%;\" align=\"justify\"><span style=\"mso-spacerun: 'yes'; font-family: Georgia; mso-fareast-font-family: \u5b8b\u4f53; line-height: 125%; font-size: 12.0000pt; mso-font-kerning: 1.0000pt;\">Excessive use of magnesium sulfate can even contaminate water supplies.<\/span><\/p>\n<p class=\"MsoNormal\" style=\"text-indent: 24.0000pt; mso-char-indent-count: 2.0000; text-autospace: ideograph-numeric; mso-pagination: none; text-align: justify; text-justify: inter-ideograph; line-height: 125%;\" align=\"justify\"><span style=\"mso-spacerun: 'yes'; font-family: Georgia; mso-fareast-font-family: \u5b8b\u4f53; line-height: 125%; font-size: 12.0000pt; mso-font-kerning: 1.0000pt;\">Before the advent of chelation therapy, magnesium sulfate was historically used to treat lead poisoning because it was hoped that any lead ingested would be precipitated by the magnesium sulfate and then eliminated from the digestive system.
