What are the effects of prolonged exposure to manure-based fertilizers on PVC?

Prolonged exposure to manure-based fertilizers can significantly impact PVC (polyvinyl chloride) materials, commonly used in agricultural applications such as irrigation pipes and storage containers. Manure contains organic acids, ammonia, and salts, which may chemically interact with PVC over time. These reactions can lead to surface degradation, reduced flexibility, and eventual brittleness, compromising the material's structural integrity. Additionally, microbial activity in manure may accelerate PVC breakdown. Studies suggest that high concentrations of nitrogen compounds and acidic conditions in manure further exacerbate these effects. To mitigate damage, farmers and manufacturers should consider protective coatings or alternative materials for long-term use in manure-rich environments. Regular inspections and maintenance are also recommended to ensure PVC durability.
