The ore can be used as an organic fertilizer and provides a cheaper alternative to producers."For the soybean crop, we reached more than those with fertilization. We arrived at the most eight sacks," celebrates the agronomist Claudia Gorge. In Jataí, researchers from the Brazilian Agricultural Research Corporation (Embrapa) are tested with the rock dust in small areas in soy. The raw material is found in the region, with positive results. "We're doing a regional search of rocks that can be used in agriculture. And here we have a reasonable group of them, which can greatly decrease the traditional inputs," explains researcher Eder Martins de Souza, Embrapa. Nutrients Also according to the researchers, the product provides nutrients such as calcium, phosphorus and potassium, which help in the recovery of the soil. The application is simple in process similar to limestone. The technique has been passed on to farmers through field days in lectures. More than 50 farmers from various regions of Goiás and even other states, attended demonstrations in the field. Embrapa researchers have shown the advantages of the use of rock dust in agriculture. Embrapa Cerrados coordinates for almost ten years Agrirocha Network, formed by about 100 researchers across the country, assessing the potential of different Brazilian rocks as sources of nutrients for agriculture. The farmer Eduardo Martins produces sugarcane and eucalyptus in Minas Gerais. Four years ago he uses the rock dust in the plantations and is satisfied with the produdutividade. But closely following the research, the search for even better results.
