  Enhanced Rock Weathering in Sandy Soils: Carbon Removal Potential and Fertility Restoration in Future Urbanization Zones
  Author(s): Hkaung Htut San*, Khin Pyone and Tsutomu SATO
  
  Enhanced Rock Weathering (ERW) has emerged as a promising Negative Emission Technology due to its dual role in atmospheric carbon dioxide removal (CDR) and soil fertility restoration. While most ERW research focuses on fertile croplands, its application in agriculturally marginal areas remains underexplored. This study investigates the efficacy of basalt-based ERW in sandy soils within Future Urbanization Zones of Kyaukse and Sintgaing townships, Mandalay Division, Myanmar, a site characterized by poor water retention, low nutrient content, and limited agricultural viability. Small-scale plantation and extraction experiments were conducted using different soil-to-basalt ratios to assess impacts on plant growth, soil mineralogy, and porewater chemistry. Eggplant growth was notably enhanced in moderate basalt-amended soils (ratios 0.9:0.1 and 0.5:0.5), while mineralogical anal- ysis rev.. Read More»
