What is the environmental impact of improper manure application?

Improper manure application can have serious environmental repercussions, primarily due to the potential for nutrient runoff and contamination of nearby water sources. When manure is not applied correctly, for example, at inappropriate times or in excessive amounts, nutrients such as nitrogen and phosphorus can wash away during rainfall or snowmelt. This runoff can lead to eutrophication in water bodies, which is characterized by excessive growth of algae, depleting oxygen levels and harming aquatic ecosystems.

Furthermore, nutrient enrichment in water bodies can lead to the proliferation of harmful algal blooms that pose risks to aquatic life and human health. This is particularly concerning as it can lead to the contamination of drinking water supplies. Therefore, understanding the implications of proper nutrient management, including careful application of manure, is critical for safeguarding environmental health and maintaining water quality.
