Name two major problems cause by usage of fertilizees?

1. Water pollution: Excessive use of fertilizers can lead to runoff of nitrogen and phosphorus into water bodies, causing algal blooms and eutrophication. This can result in decreased oxygen levels in the water, harming aquatic life and disrupting ecosystems.

2. Soil degradation: Overuse of fertilizers can lead to soil acidification, nutrient imbalances, and decreased soil fertility. This can result in reduced crop yields, increased susceptibility to pests and diseases, and long-term degradation of the soil structure.

1. Water pollution: Fertilizers can run off into waterways, causing algal blooms and other water quality problems. Algal blooms can block sunlight from reaching underwater plants, which can lead to a decline in fish populations. Fertilizers can also contribute to nutrient pollution, which can cause eutrophication of lakes and other bodies of water.
2. Air pollution: Fertilizers can also release gases into the atmosphere, such as nitrous oxide and ammonia. Nitrous oxide is a greenhouse gas, which contributes to climate change. Ammonia can also contribute to smog and other air quality problems.
