Which THREE of the following agricultural practices are most likely to have a negative impact on the environment?
Increasing the amount of fertilizer applied to a field to maximize crop yields, providing a field with excessive amounts of water to maintain ground saturation, and applying nonselective herbicides to a field at the end of the growing season to eliminate weeds are practices likely to have a negative impact on the environment.
These practices contribute to environmental degradation through nutrient runoff, water wastage, and harm to biodiversity, respectively. Each of these actions can lead to issues like pollution, soil degradation, and loss of beneficial species.
Excessive fertilizer application can lead to nutrient runoff into nearby water bodies, resulting in algal blooms and water quality issues. This practice often causes soil degradation and can harm local ecosystems, making it a negative environmental impact.
Over-irrigation can lead to waterlogging, soil salinization, and depletion of water resources. This practice negatively affects soil health and can reduce agricultural sustainability, contributing to a detrimental impact on the environment.
Nonselective herbicides kill a wide range of plants, including beneficial ones, which can disrupt local ecosystems and harm biodiversity. This practice can lead to resistance in weed populations and negatively affect soil health, making it environmentally harmful.
This practice promotes sustainable agriculture by enhancing soil structure and preventing erosion. Minimal disturbance helps maintain soil health and biodiversity, making it beneficial rather than harmful to the environment.
Practices such as excessive fertilizer use, over-irrigation, and nonselective herbicide application can lead to significant environmental issues, including pollution and biodiversity loss. In contrast, minimal soil disturbance is a sustainable practice that helps protect the environment. Understanding these impacts is crucial for implementing more environmentally-friendly agricultural practices.
