Introduction
Ammonium sulfate is a commonly used fertilizer that can also be used to lower soil pH levels. pH is an important factor for plant growth, and if the pH level is too high, plants may not be able to absorb nutrients properly. This article will give you an idea of how much ammonium sulfate is needed to lower soil pH levels.
What is Ammonium Sulfate?
Ammonium sulfate is a fertilizer that contains nitrogen and sulfur. It is usually sold in granular form and can be applied to the soil to provide plants with the necessary nutrients. In addition to being a fertilizer, ammonium sulfate can also be used to lower soil pH levels.
Why Lower Soil pH?
The pH level of the soil is important for plant growth. If the pH level is too high, nutrients may not be available to plants, even if they are present in the soil. Lowering the pH level can make nutrients more available to plants and improve their growth.
How Much Ammonium Sulfate is Needed?
The amount of ammonium sulfate needed to lower soil pH levels depends on the current pH level and the desired pH level. In general, a 1% decrease in pH level requires about 4 pounds of ammonium sulfate per 100 square feet of soil. However, this can vary depending on the soil type and other factors.
Calculating the Amount of Ammonium Sulfate Needed
To calculate the amount of ammonium sulfate needed to lower soil pH levels, you will need to know the current pH level and the desired pH level. You can use a soil testing kit to determine the current pH level. Once you know the current pH level, you can use a soil calculator to determine how much ammonium sulfate is needed.
Applying Ammonium Sulfate
Ammonium sulfate can be applied to the soil using a spreader or by hand. It should be applied evenly over the soil surface and then watered in thoroughly. It is important to follow the manufacturer’s instructions when applying ammonium sulfate to ensure that you do not apply too much and damage your plants.
Precautions
Ammonium sulfate can be harmful if ingested, so it is important to keep it out of reach of children and pets. It can also be harmful to aquatic life, so it should not be used near water sources. When applying ammonium sulfate, be sure to wear gloves and protective clothing to avoid skin irritation.
Conclusion
Lowering soil pH levels can improve the growth of your plants, and ammonium sulfate is an effective way to do so. By knowing the current pH level and the desired pH level, you can calculate how much ammonium sulfate is needed and apply it safely and effectively.
