Ferrous sulfate is generally used for spraying and flushing. Foliar spraying is sprayed according to 500 times, and flushing is applied according to 1000 times, which is exactly to meet the needs of plants for iron. Some specific plants need to be applied, and some plants like slightly acidic soil, so they can apply ferrous sulfate to adjust the PH value of the soil.
Dilute ferrous sulfate with a small amount of water before use, and then add water to stir well. Ferrous sulfate to dissolve relatively takes a little time, first with a small amount of water for dilution, constantly stirring, wait until fully dissolved, and then add the right amount of water for use, the advantage of this is that the dissolution is more sufficient.
Diluting ferrous sulfate with clean water can make ferrous sulfate safer to use and more effective. If the water quality is poor, the mineral content is high, and some dirty water will affect the effect of ferrous sulfate use, so ferrous sulfate has high requirements for water quality.
The use of ferrous sulfate must be ready to use, ferrous sulfate has strong oxygen, ferrous sulfate oxidation is not easy to be absorbed by plants. After dilution of ferrous sulfate, it begins to oxidize more than two hours, so after preparation, use it as soon as possible and do not affect the effect of use.
