Excessive fertilizer use can have detrimental consequences on soil fertility and the environment. Overapplication can lead to soil imbalances, disrupting microbial communities and depleting organic matter. Nutrient runoff from fields can contaminate water bodies, causing eutrophication and harming aquatic ecosystems. Nitrogen fertilizers contribute to greenhouse gas emissions and air pollution. Moreover, the use of certain fertilizers can lead to the accumulation of salts in the soil, negatively affecting plant growth. Sustainable fertilizer management practices are essential to prevent these adverse effects, promoting environmental health and maintaining long-term soil fertility.
