Geochemical signatures and weathering rates in soils derived from different granites in contrasting climatic locations Agronomy
Silva, Ygor Jacques Agra Bezerra da; Nascimento, Clístenes Williams Araújo do; Biondi, Caroline Miranda; van Straaten, Peter; Souza Júnior, Valdomiro Severino de; Ferreira, Tiago Osório.
We studied the mineralogical properties and chemical composition of different granites using energy dispersive X-ray spectroscopy coupled with scanning electron microscopy to understand the relationship between granite signatures and soil characteristics, including weathering patterns and soil fertility status. The discriminant analysis (DA) was based on soil physical and chemical properties and was used to differentiate soils developed from I- and S-type granites across contrasting climatic conditions in northeast Brazil. The DA identified the highest values of organic carbon, clay and plant nutrients as key variables to recognize soil profiles derived from I-type granites. In contrast, the greater sand contents and Al saturation distinguished soils...

Concentrations of major and trace elements in the soils, edible parts of crops and urine of farmers in agroecological communities Agronomy
Silva, João Paulo Siqueira da; Nascimento, Clístenes Williams Araújo do; Nascimento, Alexsandra Xavier do; Silva, Yuri Jacques Bezerra da; Biondi, Caroline Miranda.
The relationship between soil and health is important for populations that depend on the local environment to meet their nutritional needs. This study aimed to evaluate the concentrations of major and trace elements in the soils, edible parts of crops and urine of farmers in agroecological communities. We collected samples of soil, edible parts of crops and urine of farmers and family members in 23 crop fields in agroecological communities from northeast Brazil. These samples were analyzed to concentrations of Al, As, Ca, Cr, Cu, Fe, Hg, Mg, Zn, and Pb in urine and discriminant analysis and principal component analysis were used to assess the data. Concentrations of potentially toxic elements in soils and crops of agroecosystems were below regulatory...
