Final answer:
Using phosphorus-rich fertilizers is key to solving phosphorus deficiency and boosting wheat yield, while crop rotation enhances soil quality and reduces the reliance on pesticides. The correct option is (C).
Step-by-step explanation:
To solve the problem with phosphorus and increase wheat yield, the best option would be to use phosphorus-rich fertilizers. Phosphorus is critical for plant growth and is a component of key molecules such as ATP and nucleic acids.
To release phosphorus into the environment, natural processes such as rock weathering and decomposition of organic molecules play roles, but in agriculture, direct application through fertilizers is common.
Another practice that contributes to the improvement of soil fertility is crop rotation. Crop rotation involves planned sequences of various crops over time on the same field, enhancing soil nutrient levels and breaking the cycles of pests, weeds, and diseases.
This practice reduces pesticide costs and helps in preserving environmental quality by preventing excess nutrients or chemicals from entering water supplies.
The excess of nutrients like nitrogen and phosphorus can lead to ecological disturbances such as eutrophication, where microbial growth is spurred, depleting oxygen in bodies of water and creating 'dead zones' where aquatic life cannot survive.
Therefore, while phosphorus-rich fertilizers are helpful, it's critical to use them judiciously to prevent such environmental impacts.
