Excess Nitrogen In Soil – How To Amend Too Much Nitrogen In The Soil?
In some cases it is necessary to amend soil with nitrogen. For example, if you have planted a field of wheat or other crops which require high amounts of nutrients like phosphorus and potassium. If you are not able to get these nutrients from your own farm land, then you may need to add them into the soil through fertilizer application.
If you have already added too much nitrogen to the soil, then you may want to try fixing it with lime. Lime is a common chemical used in agriculture.
However, there are many different types of lime available. Some varieties contain sulfuric acid, while others do not. When using lime, you must make sure that the type of lime you use contains sulfuric acid. You can check whether a particular kind of lime contains sulfuric acid by looking at its label.
Lime is usually applied to soils where there is excess nitrogen in the soil. Limes contain either sulfuric acid or calcium carbonate (calcium hydroxide).
Sulfuric acid has many potential uses for the soil. It can act as a wetting agent, break down compounds in the soil and release nutrients into the soil, and it can also affect the soil’s pH level. It is a strong acid which can change the chemical composition of nutrients and also make them more accessible to plants.
The addition of sulfuric acid to nitrogen-rich soil should result in an exchange between nitrogen and hydrogen in the soil.
