What is the consequence of applying too much fertilizer to sandy soils?

• A. It benefits plant growth
• B. It can leach nutrients away
• C. It improves soil structure
• D. It enhances moisture retention

Answer: (B)

Applying too much fertilizer to sandy soils can lead to nutrient leaching. Sandy soils have a coarse texture with larger particles, which results in greater pore spaces and less ability to retain water and nutrients compared to finer soils, such as clay. When excess fertilizer is applied, the nutrients dissolve in water and, due to the rapid drainage characteristics of sandy soils, can easily wash away or leach deeper into the soil profile. This leaching not only deprives the plants of essential nutrients they need for healthy growth but can also lead to groundwater contamination. It highlights the necessity for careful nutrient management, especially in sandy soil types, to ensure that plants receive the right amount of fertilizer without risking the loss of those nutrients from the root zone.
