The nutrient geotextile is composed of a layer of non-woven fabric and a layer of animal and plant fiber felt layers. The decomposition of plant fibers in the felt layer can enhance the anti-penetration ability of plant cells. After the decomposition of animal keratin fibers, it can be long-term plants. Provide nitrogen fertilizer.

Nutritional geotextile is a functional non-woven geotextile specially designed for the protection of green concrete (concrete-bearing concrete). The non-woven geotextile can be evenly laid under the green concrete slab, and a layer of felt which can slowly decompose the plant is compounded on the surface of the non-woven fabric, and the plant is maintained at the same time as the filtration performance of the non-woven geotextile. The plants on the green belt provide long-term slow-release fertilizer, which solves the problem of insufficient sustained-release fertilizer in the filling material due to limited space in the gap of the green concrete.
