The correct answer is: All of the above.
Excessive use of chemical fertilizers in Punjab can potentially lead to:
- Soil degradation. Chemical fertilizers can leach into groundwater and pollute surface water. They can also runoff into streams and rivers, causing algae blooms and fish kills. When fertilizers are not used properly, they can also damage soil structure and reduce its ability to hold water.
- Water pollution. When fertilizers are not used properly, they can leach into groundwater and pollute surface water. They can also runoff into streams and rivers, causing algae blooms and fish kills.
- Reduced crop yields in the long term. Over time, the use of chemical fertilizers can lead to soil degradation, which can reduce crop yields. Additionally, the use of chemical fertilizers can select for weeds and pests that are resistant to these chemicals, which can also reduce crop yields.
It is important to use chemical fertilizers carefully and responsibly to avoid these potential problems.
