Which of the following fertilizers should be applied for good plant growth after prolonged use of sulphate of ammonia on a neutral soil?
Answer Details
Prolonged use of sulphate of ammonia (a fertilizer containing ammonium sulfate) on a neutral soil can lead to soil acidification over time, which can adversely affect plant growth. Therefore, the fertilizer that should be applied for good plant growth in this case is one that can help neutralize the acidity of the soil. Lime is commonly used to raise soil pH, and so it is the best choice for neutralizing the acidic effects of prolonged use of sulphate of ammonia on a neutral soil. Ammonium nitrate, urea, and single superphosphate do not have the same soil pH-neutralizing properties as lime and are not effective in addressing the issue of soil acidification caused by the prolonged use of sulphate of ammonia on a neutral soil.
