In recent research conducted in Gilan Province, Iran, the impact of wood ash and lime on improving the pH and biological properties of acidic soils has been explored, shedding light on sustainable practices that could benefit various sectors, including construction. The study, led by آناهیتا رمضانی, a master’s student at the Department of Soil Science at the University of Gilan, reveals significant insights into the long-term effects of these natural amendments on soil health.
As the construction industry increasingly seeks sustainable materials, the findings of this research could pave the way for the use of wood ash as a soil amendment in landscaping and green building projects. “Our results indicate that while lime effectively raises soil pH more quickly, wood ash enhances organic carbon levels and biological activity over time,” رمضانی stated. This dual impact could lead to healthier soils that support vegetation, an essential consideration for eco-friendly construction practices.
The study focused on two samples of acidic soil from the Fuman region, with initial pH levels of 2.5 and 3.4. By adding calculated amounts of lime and wood ash, researchers monitored changes in soil properties over six months. Notably, while lime increased the pH to 7 and 7.2 in the two soil samples, wood ash also contributed positively by raising the pH to 5.7 and 6.3, respectively.
The implications of these findings extend beyond agriculture. For the construction sector, improved soil health can enhance the viability of land for development, reduce erosion, and promote sustainable landscaping practices. As urban areas continue to expand, integrating such natural amendments could lead to more resilient ecosystems.
“By using wood ash in soil amendments, we not only improve soil quality but also recycle waste materials, aligning with sustainability goals,” رمضانی added. This perspective resonates with the growing trend towards eco-conscious construction methods, where minimizing environmental impact is crucial.
The study, published in the journal “Soil Management and Sustainable Production,” highlights the importance of considering both chemical and biological soil properties in land management practices. As the construction industry adapts to these findings, we may see a shift towards more sustainable practices that leverage natural materials for improved soil health.
