Answer
The major disadvantage of using chemical fertilizers is environmental pollution and soil degradation. Excessive fertilizer use leads to nutrient runoff into water bodies, causing eutrophication where algae blooms deplete oxygen and harm aquatic life. Over-reliance on fertilizers can reduce soil organic matter, disrupt beneficial soil microorganisms, and cause soil acidification. Long-term use may also lead to nutrient imbalances, reduced soil fertility, and groundwater contamination with nitrates, posing health risks.
