| Research Abstract |
Up to 20 L of vinasse can be generated for every 1 L of bioethanol produced. Therefore, it has become important to establish a sustainable system for recycling vinasse that includes its application to land. To better understand the effect of vinasse application on soil environment, we investigated growth of microorganisms because it is rich in nutrients, reduction in hydraulic conductivity due to physical clogging of soil pores by suspended solids and biological components, soil water repellency due to microbial activity, and transport property of dissolved organic matter from sugarcane-molasses ethanol vinasse in soils. Our study suggested that soil physical properties should be considered in order to develop an appropriate method for application of vinasse to land.
