According to data from the IPCC (2007), agriculture is one of the economic sectors accountingfor the most greenhouse gas emissions. Conventional nitrogen-based fertilizers are mostcommonly used in agriculture, and nitrogen is lost very quickly as their componentsdecompose. The generally low efficacy of nitrogen-based fertilizers not only leads to technicaland economic losses, but also contributes to higher concentrations of greenhouse gases in theatmosphere by releasing nitrous oxide (N 2 O), a gas that is nearly 300 times more potent thancarbon dioxide (CO 2 ) in terms of its effects on the ozone layer. On the other hand, fertilizersthat release nitrogen (N) more slowly are expensive to produce, even though they are moreeffective. Within this context, new fertilizer production technologies could help reduce theseproblems. Biochar could offer an alternative for developing slow-release fertilizers containingnitrogen and minerals. The objective of this study is to develop an organic mineral fertilizerbased on biochar and verify impacts on N 2 O emissions and agricultural performance inpastures and corn to determine prospects for industrial application.
