Mining and agriculture go hand in hand, says president director
This statement by the director-president of the Geological Survey of Brazil (CPRM), Esteves Colnago, took place in the opening speech of the Seminar Remineralizers of Soils, held on June 17 and 18, in Brasília. Esteves Colnago pointed out that CPRM has intensified the prospecting of inputs for agricultural fertilizers (phosphorus and potassium), as part of initiatives that aim to reverse the high dependence on imports of these inputs.
The event was attended by representatives from the Ministry of Mines and Energy, the Geological Survey of Brazil, Embrapa, the National Mining Agency, the Defense and Agriculture Secretariat of MAPA, the MCTIC Secretariat for Entrepreneurship and Innovation and the Secretariat of Family Agriculture and Cooperatives of MAPA.
The seminar discussed the legal framework for soil remineralizers, the current status of records and the modernization of legislation for these inputs. Studies were also presented addressing the prospects for using waste from the mineral activity, and and was emphasized the need to adapt agronomic tests that should validate the performance of these new inputs
At the opening ceremony, president director Esteves Colnago praised the work being carried out by CPRM specialists in partnership with the Remineralizers Working Group, in expanding knowledge of the potential for the production of this new category of fertilizers.
“The working group has been dedicated to developing practices to characterize, quantify and take advantage of mining waste materials. We believe that mining and agriculture go hand in hand ”, emphasized the president director.
Still at the opening, the executive secretary of the Ministry of Mines and Energy, Marisete Dadald, spoke about the importance of remineralizers for mining and agribusiness. "The insertion of new technologies, resulting from studies such as that of the Remineralizers Working Group, allows to extend the useful life of the enterprises, reducing the impacts on the affected communities, which contributes to the sustainable strengthening of the Brazilian mineral sector", said Marisete.
The WG was established in 2012 and is coordinated by the Secretariat of Geology, Mining and Mineral Transformation, with the objective of regulating and working for the implementation of a new technological route capable of increasing soil productivity with low environmental impact, reducing dependence on Brazil imported fertilizers. The expectation is to value and make natural resources more efficient, with low waste generation and social equity.
In her lecture, researcher Magda Bergmann emphasized that the participation of ministries in basic productive arrangements is important, in order to enable the use of the materials that CPRM indicates. Although the Agromineral Projects of the Geological Survey of Brazil carry out a whole job of characterizing and estimating reserves of remineralizers, the opportunities to add materials to this practice often depend on productive arrangements that can and should be encouraged, especially when it comes to small mining.
For Paulo Romano, special advisor to the presidency and member of the working group, the remineralizers work in the perspective of the importance for the sustainability of Agriculture and in strengthening the micro-regional economy. “The biomineralization process, which is intense in our tropical environment, facilitates the release of nutrients for plants. Therefore, CPRM in its partnership with EMBRAPA inserts its activities in the context of bioeconomics, strategic for Brazil and integrates geological and agronomic knowledge ", emphasizes Paulo Romano.
Agrogeological Zoning of Brazil launched - During the seminar, Agrogeological Zoning of Brazil was also launched. It is a technical-scientific instrument built from the interaction of data already available between the Geological Survey of Brazil (CPRM / SGB) and Embrapa. CPRM provided information on the country's geological mapping, and Embrapa, in turn, aggregated information on soils and agricultural crops to provide subsidies for research, technical assistance and rural extension, and also to guide decision makers in establishing public policies sustainability of the agro-industrial and mineral sectors.
What are remineralizers?
Remineralizers are materials of mineral origin that are reduced by mechanical processes. The use of these inputs makes it possible to change soil fertility rates, as they offer macro and micronutrients for plants. This procedure promotes the improvement of the physical and physical-chemical properties or biological activity of the soil, and can help to reduce the use of fertilizers, in addition to enabling the practice of more sustainable and organic agriculture.
