The Agriculture and Agrarian Reform Commission (CRA) will hold a public hearing on Thursday (28), at 8 am, to discuss the use of remineralizers as an alternative for soil management and use. According to the website of the Brazilian Agricultural Research Corporation (Embrapa), soil remineralizers are mineral inputs that can provide macronutrients and micronutrients, in addition to other beneficial elements for plants. Elements such as calcium, magnesium, potassium, copper, iron, manganese, silicon and zinc can be used.

Remineralizers are regulated in Brazil by Law 12,890/2013 and Normative Instruction 05/2016 of the Ministry of Agriculture, Livestock and Supply (MPLSA). "The regulation is a guarantee for producers and consumers of soil remineralizers, as it imposes criteria for the production, registration and trade of these new inputs", explains the Embrapa website. Certain ground silica rocks have characteristics such as soil remineralizers, one of the categories of silicate agrominerals.

They have the potential to act as soil conditioners, as suppliers of regional nutrients, in addition to forming new functional mineral phases in the soil. Studies of agronomic efficiency indicate that agrominerals applied to the soil have short, medium and long term effects in annual cropping systems.“Further studies, however, are necessary to evaluate the management technology of these inputs and in different cropping systems”, notes the publication.

The request for the debate was presented by Senator Acir Gurgacz (PDT-RO), president of the commission, informs "Agência Senado". The chief general of Embrapa Cerrados, Sebastião Pedro da Silva, and the president of the Associated Group for Sustainable Agriculture (GAAS), Rogério Vian, are invited to the audience. Rounding out the list of debaters are the president of the Brazilian Association of Soy Producers (Aprosoja Brasil), Antonio Galvan, and agronomist Antônio Alexandre Bizão, a researcher in the area of technology transfer.
