Regular use of which of the following fertilizers increases the acidit...
Explanation:
Fertilizers are substances that are added to the soil to enhance plant growth and increase productivity. However, the use of fertilizers can also affect the pH of the soil. The pH of the soil is a measure of its acidity or alkalinity, and it is important for plant growth as it affects the availability of nutrients in the soil.
The regular use of Ammonium sulphate fertilizer increases the acidity of the soil. This is because Ammonium sulphate fertilizer contains ammonium ions (NH4+) which are acidic in nature. When ammonium ions are added to the soil, they react with water to form ammonium hydroxide (NH4OH), which releases hydrogen ions (H+) into the soil. These hydrogen ions then lower the pH of the soil, making it more acidic.
On the other hand, Potassium nitrate and Urea fertilizers are neutral in nature and do not affect the pH of the soil. Superphosphate of lime fertilizer, on the other hand, contains calcium ions (Ca2+) which are basic in nature and can increase the pH of the soil.
In conclusion, the regular use of Ammonium sulphate fertilizer can increase the acidity of the soil, which can affect plant growth and productivity. It is important to monitor the pH of the soil and use fertilizers accordingly to maintain a healthy balance of nutrients in the soil.
