Abstract：
Soil degradation threatens agricultural productivity and food supply, leading to hunger issues in some developing regions. To address this challenge, we developed a low-cost, highly efficient, and long-term stable soil improvement method. We chose polyvinyl alcohol (PVA), a commercially available polymer that is safe and non-degradable, to serve as a soil adhesive. We mixed PVA solution into the soil and applied a drying treatment to enhance the bonding between PVA and the soil, achieving highly water-stable soil. This PVA-stabilized soil exhibits low bulk density, high porosity, and high permeability, making it an ideal substrate for planting. In a germination test, the PVA-stabilized soil revealed a higher germination rate and growth rate compared to those of the non-treated soil. We believe this simple and efficient soil improvement method can restore degraded soil and contribute to sustainable agriculture.
摘要：
土壤退化威胁着农业生产力和粮食供应，导致一些发展中地区的饥饿问题。为了应对这一挑战，我们开发了一种低成本的，高效,和长期稳定的土壤改良方法。我们选择了聚乙烯醇（PVA），一种安全且不可降解的市售聚合物，用作土壤粘合剂。我们将PVA溶液混合到土壤中，并进行干燥处理以增强PVA与土壤之间的结合，实现高度水稳定的土壤。这种PVA稳定的土壤表现出低的容重，高孔隙率,和高渗透性，使其成为种植的理想基质。在发芽试验中，与未处理的土壤相比，PVA稳定的土壤显示出更高的发芽率和生长速率。我们相信这种简单有效的土壤改良方法可以恢复退化的土壤，并有助于可持续农业。
