Influence of sulfur on selenium absorption in strawberry Agronomy
Santiago, Franklin Eduardo Melo; Silva, Maria Ligia de Sousa; Ribeiro, Flaviane de Oliveirra; Cipriano, Patriciani Estela; Guilherme, Luiz Roberto Guimarães.
Selenium (Se) is an essential mineral element for animals and humans, and attention has been devoted to Se biofortification of agricultural crops. Due to the scarcity of studies aimed at guiding the nutritional Se-enrichment on strawberry and the need to understand the interaction between Se and sulfur (S) in this cultivation, the objective of this study was to evaluate the effect of the application of Se and S levels on the nutrition and production of strawberry. Treatments consisted of five levels of Se (0, 0.3, 0.6, 1.2, and 2.4 mg dm-3 as sodium selenate) and two levels of S (0 and 60 mg dm-3 as gypsum), which were applied in dystroferric Red Latosol soils under greenhouse conditions. The concentration and accumulation of Se are drastically reduced in...

Fast immersion to test the stability of aggregates in water: consequences for interpreting results from tropical soil classes Agronomy
Silva, Rodrigo Fonseca da; Cipriano, Patriciani Estela; Siueia Junior, Matias; Mars, Geslin; Dias Junior, Moacir de Souza.
Aggregates are the primary structural components of soil and have been used as an indicator of soil quality in conservation systems. The objective of this study was to analyse the effect of slow pre-wetting on the results of the aggregate stability test for different classes of tropical soils. Data were arranged in a 2 x 4 factorial design with three replications, in which the first factor comprised the two methods of pre-treatment on soil aggregates: without pre-wetting (WOPW), which considered the moisture of the aggregates in the field, and with pre-wetting (WPW), which considered the slow wetting of aggregates through capillarity on wet filter paper for 24h. The second factor consisted of four soil classes: Typic Dystrustept (Cambissolo Aplico...
