The use of fertilizer can have a negative impact on the environment in several ways. First, fertilizers can increase the levels of nutrients in the soil, especially nitrogen and phosphorus. When these nutrients are washed away by rain or irrigation, they can enter nearby water sources and cause eutrophication, which is the excessive growth of algae and other aquatic plants that deplete oxygen in the water and harm aquatic life.
Second, the use of chemical fertilizers can affect the pH balance of the soil, making it more acidic or alkaline, which can harm native plant species and disrupt natural ecosystems.
Third, many fertilizers are manufactured using fossil fuels, contributing to greenhouse gas emissions and climate change. Finally, the runoff of fertilizers also increases the level of greenhouse gases, namely, nitrous oxide, which can contribute significantly to climate change.
Therefore, while the use of fertilizers can increase crop yields, it is important to use them in moderation and responsibly to minimize their negative impact on the environment. Organically sourced fertilizer that doesn't contain synthetic chemicals can be created, which considerably reduces the damage of chemical fertilizers on the environment.
