Manganese determination by GFAAS in feces and fish feed slurries
This paper presents a simple, fast and sensitive method to determine manganese in samples of feces and fish feed by graphite furnace atomic absorption spectrometry (GFAAS) by the direct introduction of slurries into the ...
Concentrations of Cu, Fe, Mn, and Zn in tropical soils amended with sewage sludge and composted sewage sludge
Sewage sludge may be used as an agricultural fertilizer, but the practice has been criticized because sludge may contain trace elements and pathogens. The aim of this study was to compare the effectiveness of total and ...

Contents and main fractions of trace elements in Typic Argiudolls of the Argentinean Pampas
(Taylor & Francis, 2000-12)
The knowledge of the trace elements in soils of the Pampas remains fragmentary. Agriculture has been intensified in this region increasing the crop demand of micronutrients and increasing the use of fertilizers, which could ...
Bioavailability of Nutrients in Seeds from Tropical and Subtropical Soybean Varieties
(Taylor & Francis Inc, 2016-01-01)
The selection of varieties or species of plants with higher nutrient uptake efficiency and nutrient concentration for biofortification of food crops is a key tool to reduce malnutrition. Soybean (Glycine max L. Merr) is ...
