Release of nutrients and organic carbon in different soil types from hydrochar obtained using sugarcane bagasse and vinasse

Hydrothermal carbonization of byproducts from the sugarcane industry generates a solid material (hydrochar) rich in carbon and nutrients with the potential to be used as a soil conditioner. In this context, the objective of this work was to evaluate the nutrient release process from hydrochar with the aim of improving soil quality. To do this, experiments were performed evaluating the concentration of NO3−, PO4−3, K, Ca, Mg, Fe and total organic...
