Uses of Iron Sulphate
Iron sulphate has several uses as it is an iron ion carrier. It is used in agriculture to supply iron to plants and is used to stain concrete floors.
Iron sulphate for plants. Sometimes plants are deficient in micronutrients, and this may be due to a high pH of the soil, a high alkalinity, which makes the nutrients insoluble, retaining them and thus making them unavailable to the plants. Ferric sulphate is a salt that can be used to lower the pH of the soil, thus releasing micronutrients and providing a supply of iron.
Iron sulphate for painting. Especially for concrete walls on farms, ponds, stairs, when painting with this material it will give you a very special and characteristic reddish surface colour. This effect is achieved by the oxidation of iron ions when dissolved in water.
