Purpose To ensure the sustainability of rice husk recycling schemes, there are essential conditions that should be considered. In this study, a system in which a fertilizer was obtained after rice husk heat treatment, which also produces hot water as a heat recovery strategy, was considered, and its financial sustainability, based on different conditions in […]
Purpose The solubility of silica is a key parameter affecting its suitability as a rice fertilizer. Therefore, this study determined the effect of calcination temperature and duration on the physical composition of silica derived from rice husk ash. Method Rice husks were calcined at 100–900 °C for 15–120 min in an electric furnace. The solubility […]
Purpose This study aims to evaluate the potential negative effects of rice husk as a source of fertilizer on plant growth. Method Growth tests were conducted on komatsuna (Brassica rapa var. perviridis) using three types of experiment. A pot experiment was conducted to compare different fertilizers on an individual basis. A second pot experiment was conducted […]
