<p>Bioprocess for extracting silicon from the agro-industrial waste rice husk using the natural extractant citric acid, which is derived from waste from the citrus industry, for developing an organic silicate fertilizer, particularly a bioprocess for extracting silicon from the agro-industrial waste rice husk using the natural extractant citric acid, which is derived from waste from the citrus industry, for developing an organic silicate fertilizer with the technological aim of providing an organic source of silicon from various agro-industrial wastes, through the extraction thereof by the processes of fermentation and decoction. The ideal process for extracting silicon has been defined in this first step, for providing silicon content in manure both when it is elaborated and after it has been sitting for three months, and also for lowering pH values and for increasing the concentrations of macro- and micronutrients. An increase in the use of said wastes has been observed due to the agro-industrial generation of large quantities thereof. In the second step of the invention, the process for elaborating the fertilizer was optimized, as well as the form of the wastes being altered.</p> |
