Plants require nutrition the same as humans to perform the growth process. Metallic salts as nutrients are used to maintain the fertility of soil insuring healthy farms and maximum production. Magnesium Sulphate as fertilizer is used to treat magnesium deficiency in plants and in the soil. It is very important to perform a soil test prior to a plantation of seeds in farms to treat the deficiency at the source level. Cabbage, corn, cucumber, eggplant, melon, pepper, potato, tomato, watermelon, bananas, citrus fruits, apples, and grapes are more sensitive to magnesium deficiencies and if one is targeting among such plants then magnesium deficiency should be identified and treated with Magnesium Sulphate.
Sulfur in Magnesium Sulphate acts as a major component of protein. The development of enzymes and vitamins is boosted with the sulfur content of Magnesium Sulphate and it is necessary for metabolic activity, photosynthesis, and other circulation processes of starch and sugar. Sulfur also helps in maintaining the pH of the soil. With magnesium deficient soil, the growth of plants is resisted at a certain point. The natural green color is lost and leaves appear with pale yellow spots. With the serious depletion of magnesium reddish-purple, leaves might appear that put the growth of the plant to minimal rate by which the ripening process of fruits takes more time than expected.
Magnesium Sulphate is used when natural magnesium is washed away with certain natural causes like rain or the same crop planted consecutively that uses major magnesium content in soil; some artificial reasons like pH level of soil are too low and use of ammonium, calcium and potassium fertilizers is done in excess.
Magnesium Sulphate is highly soluble in water and in majority cases, it is used directly by dissolving the calculated amount in water via hand spray or with the sprinkler system. Different plantation requires different content of Magnesium Sulphate and it is advised to distribute the fertilizer at a time when fruiting starts with regular intervals of 15 days as far as treatment requires. Usually, 2 to 3 times are enough if magnesium deficiency is not extreme. Fruits require less magnesium than vegetables and flower plants. Usually, Magnesium Sulphate is sprayed directly over plant leaves after magnesium deficiency is observed by dissolving 200 to 300 grams of Magnesium Sulphate into 100 liters of water. Melons and some field vegetables require more concentration up to 500 grams Magnesium Sulphate in 100 liters of water. Treatment should be done until the natural green color of plants and leaves is achieved.
Hence, Magnesium deficiency not only tempers the appearance of plantation but it also leads to loss of production if not identified and treated as soon as possible.
