What are the effects of prolonged exposure to garden soil on composite materials?

Prolonged exposure to garden soil can significantly impact composite materials, leading to degradation and reduced durability. Soil moisture, microbial activity, and chemical composition contribute to corrosion, weakening structural integrity. Studies show that organic acids and salts in soil accelerate material breakdown, particularly in polymer-based composites. UV radiation and temperature fluctuations further exacerbate these effects. Regular durability testing is essential to assess long-term performance. Understanding these factors helps in designing more resistant composites for outdoor applications. Mitigation strategies, such as protective coatings or soil-resistant additives, can extend material lifespan. Research continues to explore innovative solutions for enhancing composite resilience in soil-rich environments.
