How do composite materials prevent discoloration from fertilizer runoff?

Composite materials are increasingly used to prevent discoloration caused by fertilizer runoff due to their unique properties. These materials, often made from polymers, fibers, or resins, are designed to resist chemical reactions with fertilizers, which can lead to staining or degradation. Their non-porous surfaces prevent absorption, while protective coatings add an extra layer of defense. Additionally, composites are UV-resistant, reducing fading from sun exposure. By combining durability with low maintenance, composites offer a long-term solution for structures exposed to agricultural chemicals, ensuring aesthetic and functional longevity.
