Agrogeological Principles on Soil Remineralization and Brazilian Protagonism
摘要
The application of silicate rock dust to enhance soil fertility and quality represents a vital strategy for countries heavily dependent on imported soluble fertilizers, particularly those localized in tropical regions where agricultural soils are highly weathered. Brazil faces this scenario and, as a result, must explore innovative technological approaches to sustain agricultural productivity, economic viability, and food and environmental security. With its rich geodiversity and extensive agricultural sector, Brazil is well positioned to capitalize on technologies that harness the diverse silicate-rich rocks located near its agricultural regions. Additionally, the country benefits from a regulatory framework that sets standards to ensure the agronomic efficiency and environmental safety of these materials, defined as soil remineralizers (REM). In light of these considerations, this chapter aims to outline the key aspects of Law 12,890/2013 and Normative Instruction 05/2016, highlighting the requirements set forth by these regulations, as well as the main advantages and limitations associated with the utilization of REM. These legal measures of Brazil integrate geochemical and mineralogical parameters for rock characterization and are based on methodological principles that adhere to recognized scientific practices in agrogeology. By doing so, they illustrate the connection between regulatory criteria and existing scientific methodologies in the field. In conclusion, the combination of Brazil’s vast natural resources, regulatory framework, and agricultural potential creates a favorable environment for the adoption of REM. However, to fully constrain this potential, it is essential to develop new public policies focused on financing and capacitating technicians in the use and benefits of remineralizers. Additionally, holding training courses and providing information on the benefits of applying REM for rural consultants and extension agents would significantly increase the chances of success. This will ensure broader implementation and maximize the positive impact of this technology on Brazilian agriculture.
