Rendimento Energético e Qualidade do Biofertilizante da Batata-Doce

Abstract

Among the agriculture challenges, high yield, reducing the negative impact on environment, becomes increasingly important. In this sense, integrated crop systems are studied. The Brazilian energy matrix is based on hydroelectric plants, however, the temporal and volumetric irregularity of rainfall regime create uncertainties regarding the sustainability in this resource for energy generating. The strategy using renewable energies that reduce the environmental impact and reduce financial and social costs is discussed and disseminated in presented scenario. Evidence shows that sweet potato tubers, as they have a high carbohydrate content, are promising as a strategy for energy generating when compared to crops such as grains. This evidence leads to the hypothesis that sweet potato after anaerobic fermentation results in higher biogas volume, besides providing biofertilizer with a higher concentration of essential nutrients for agricultural crops. Thus, the objective of this research project is to evaluate the e
