Explanation:
Fertilizers provide nutrients to plants, where the most needed nutrients in agriculture are nitrogen, phosphorus and potassium. Negative media coverage of the role of agriculture in pollution can make farmers feel guilty about the use of fertilizers. However, reducing fertilizer input can slow plant growth and exacerbate problems such as soil erosion. While it is important to be aware of the effects of fertilizers and use them with caution, it is also important for everyone to recognize that agricultural fertilizers are not the main source of pollution. If the plant uses all the nutrients and uses fertilizer wisely to prevent leaching, there is little chance of contamination.
Nitrate leaching from the soil poses a serious health risk and can contribute to soil acidification. When high levels of nitrogen are used, or when clover grass meadows fix significant nitrogen, nitrates inevitably seep out into groundwater where the water table is present, especially in sandy or well-drained soils. There is a possibility of entering. When this groundwater is used for domestic supply, leaching poses a serious health risk.
