Lowering Soil Ph Using Aluminum Sulfate
The method of reducing the pH of soil with aluminum sulfate
If you want to reduce the pH of soil, it is a good policy to apply aluminum sulfate.
If aluminum sulfate enters the water, it will dissociate, and aluminum ions and sulfate ions will be produced. Aluminum ions meet water in the soil and hydrolyze to produce hydrogen ions. As hydrogen ions increase, the pH of the soil will gradually decrease.
The method of applying aluminum sulfate is the first to understand the current situation of the soil. Measure its pH, texture and nutrients to know the amount of aluminum sulfate needed. If the soil is clay, its ability to maintain fertilizer and water is strong, and the amount of aluminum sulfate should be used more; if it is sand and it is easy to lose, the amount should be less.
The dosage is established, and the method of application should be considered. Or sprinkle it on the surface of the soil, and then plow it, so that it can be mixed with the soil; or dissolve it in water and apply it by irrigation. When applying, avoid the roots of the crop and fear injury.
After applying aluminum sulfate, always measure the soil pH and observe its change. If the drop is excessive, lime can be applied to adjust it, so that the soil pH is in line with the needs of crop growth. In this way, using aluminum sulfate to reduce the soil pH can be appropriate and help crops thrive.
