Parana basin basalt powder: A multinutrient soil amendment for enhancing soil chemistry and microbiology

ABSTRACT: This study evaluated the effects of Paran´a Basin basalt powder, a mining byproduct from southern Brazil, on the macro- and micronutrient content of two soil types, Oxisol (OX) and Typic Quartzipsamment (TQ), as well as the metabolic activity of soil microorganisms. Basalt powder doses were determined based on CaO levels required to correct Ca2+ levels in each soil, ranging from 0 to 4 times the recommended amount. Soil samples were collected for analysis after 60 and 170 days of incubation to assess soil attributes. Additionally, a laboratory study examined soil basal respiration (SBR) after 168 days of greenhouse incubation. The ...

STONEMEAL IN THE SOUTH OF MARANHÃO AND PIAUÍ STATES

According to forecast analysis based on strategic planning tools, the current model of agriculture practiced in the southern plains of Maranhão and Piauí states (Brazil) is unsustainable in the medium and long terms. Elaborated geological surveys in this region are pointing to large deposits of rocks and agrominerals, which can facilitate the practice of stonemeal. This could contribute to the conservation of soils and water resources. https://www.researchgate.net/publication/295099176_Anais_do_II_Congresso_Brasileiro_de_Rochagem_coletanea_de_varios_autores
