Thermophosphate consists of the thermal treatment of the rock, with or without addition of other materials, being an excellent source of phosphate fertilizer, presenting other nutrients and beneficial elements such as Mg and Si. In this work were used Al-phosphates from Sapucaia (Bonito, State of Pará) and slag of the blast furnace (Marabá, State of Pará), in the ratio 80/20, being subjected to calcination at 700 ºC and 1100 ºC with the objective of verifying the behavior of crystalline phases in these temperatures. The samples were calcined and then characterized by X-ray diffraction (XRD). These analyzes showed that the phosphate ore consists of phases of the crandallite group and quartz and the slag by amorphous material. After calcination at 700°C, the phases of the thermophosphate and slag-thermophosphate are restructured tending to amorphous, except quartz. At this temperature, the solubility of the phosphate material favors the increase in P2O5 content. At 1100° C the identified crystalline phases were: aluminum oxide, aluminum and iron phosphates, calcium and iron phosphates, and silicon oxide. Studies evaluating these materials in agriculture may determine their agronomic efficiency. |

Direct sowing has been proposed as an alternative to planting seedlings because of its low cost. However, there are still few works with direct seeding that aim to select species that best respond to the technique. Therefore, we carried out a direct sowing study with native tree species of the Semideciduous Seasonal Forest in Southern Brazil (Serra do Sudeste, State of Rio Grande do Sul). |
