1. Forms of sulfur in Brazilian Oxisols under no-tillage system / Formas de enxofre em Latossolos sob sistema plantio direto
Soil is a critical component of the global sulfur (S) cycle acting as source and a sink for various S species and mediating changes of S oxidation states. However, very little is known about the identities of these specific organic and inorganic S containing molecules, especially in Brazilian soils under no-tillage (NT) system. Thus, the objectives of this s

5. Concentration of 226Ra in soil and sugar cane after application of calcareous, gypsum or phosphogypsum / ConcentraÃÃo de 226Ra em solo e em cana-de-aÃÃcar apÃs aplicaÃÃo de CalcÃrio, Fosfogesso ou Gipsita
All kinds of soil possess 226Ra, and its absorption by the plants, depends on the specific characteristics of each region and of the cultivated species. In different parts of the world, radioecological studies are currently developed to evaluate the transferences of 226Ra in the soil-plant system and the presence of this radioelement in human nutrition. In r
