Potencial de produção de grãos brasileiros via fertilização e impactos nas emissões de CO2eq

Resumo

For all Brazilian municipalities, data of planted area, quantity produced, types of soil and soil use, for Rice, Beans, Wheat, Corn and Soybeans, was collected. With the aid of a Geographic information System (GIS) maps were drawn, and by cross-checking them, crop yields per type of soil in anthropized areas were obtained. From the expected yield on the application rate of fertilizer per level of availability of primary major nutrients (Nitrogen, Phosphorus and Potassium) in the soil, recommended by Embrapa (WebAgritec), it was considered that each municipality, without area expansion as from its actual productivity value in 2011/12, would increase to the maximum xpected value related to the recommended application rate of fertilizers on the upper range of productivity. A period of ten years was considered for the rise of productivity level, which allowed a time horizon of the estimates from 2011/12 to 2061/62. The Fertilization Consumption, Application Rate and Efficiencies for the primary major nutrients, as well as the Balances of CO2eq, required for these new conditions, were projected. The horizon and the resulting volume of agricultural production were compared to the projections of MAPA (Ministério da Agricultura, Pecuária e Abastecimento and Outlook Fiesp 2023, whose horizon projections are 2021/22 and 20022/23 respectively. The potential volume of agricultural production via fertilization of these five cultures and the impact on the balance of CO2eq are then measured, thus culminating with the possibility of significant advances in this volume in terms of the number of harvests and the beneficial effect on the balance of CO2eq, allowing, due to the spared areas, significant postponement of emissions of CO2eq
