By nature-based solutions and a sustainable approach, this research aims to develop high water-retaining and pH-adjustable soil conditioners with ionic and nanoparticulate plant nutrients, by investigating the effect of key components and the factors influencing their stability in an aqueous system. First, we speculate that the stability of the combination is influenced by the conductivity, pH, and dispersion of important ingredients, such as bagasse ash. Our primary research topic is whether different rheological modifiers, such as dispersing, stabilizing, and compatibilizing agents, may have an impact on stability. Consequently, the optimal bagasse-ash liquid suspension containing stearic acid as a dispersing agent, d-chitosan as a stabilizing agent, and carboxymethyl cellulose as a water-retaining agent is found to be stable. This formulation can help improve the quality of such infertile soils as bare sand during the plantation of green bean seed. From electron microscopy, it is believed that CaO could be the physical origin of the excellent water absorption ability of bagasse ash. Finally, the multicompositional formulations are also stable as pH adjusters. The findings confirm the versatility of our approach to formulate stable aqueous-based soil conditioners and their applicability toward different types of soil under the varying effects of heat and draft from climate change worldwide.
通过基于自然的解决方案和可持续方法,本研究旨在通过研究关键成分的影响以及影响其在水体系中稳定性的因素,开发具有离子和纳米颗粒植物养分的高保水和pH可调节土壤改良剂。首先,我们推测这种组合的稳定性受甘蔗渣灰等重要成分的电导率、pH值和分散性影响。我们的主要研究课题是不同的流变改性剂,如分散剂、稳定剂和增容剂,是否会对稳定性产生影响。因此,发现以硬脂酸为分散剂、d-壳聚糖为稳定剂、羧甲基纤维素为保水剂的最佳甘蔗渣灰液体悬浮液是稳定的。这种配方有助于在种植绿豆种子时改善诸如裸沙等贫瘠土壤的质量。从电子显微镜观察可知,CaO可能是甘蔗渣灰优异吸水能力的物理来源。最后,多成分配方作为pH调节剂也是稳定的。这些发现证实了我们配制稳定水基土壤改良剂方法的通用性及其在全球气候变化导致的不同热和干旱影响下对不同类型土壤的适用性。
