Direct and subsequent effect of compost and poultry manure on the bioavailability of cadmium and copper and their uptake by oat biomass

Abstract

Direct and subsequent influence of added organic materials on changes of cadmium and copper bioavailability in soil and their accumulation in aboveground oat (Avena sativa L.) biomass was studied in a three-year experiment. Mineral NPK, poultry manure and two types of composts were used as fertilizers. The average portion of available cadmium and copper from their total content in soil in all treatments was 0.94% and 0.25%, respectively. After application of poultry manure the concentration of available Cd increased during experimental years, contrary to Cu. The Cd uptake increased proportionally with available Cd content in soil almost in all treatments during experimental years (correlation coefficient R = 0.54; P < 0.05). The Cu uptake was however different than Cd uptake, mainly in the second and third year. The lowest uptake of Cu was found in the first experimental year and was in close positive correlation with yields of dry biomass.

Changes in cadmium mobility during composting and after soil application

“…In our previous studies, we tested the effect of lime, limestone, bentonite and zeolite as ameliorative materials (Hanc et al, 2006), and the effect on Cd mobility of poultry manure and composts as organic materials (Hanc et al, 2008). One of the most effective stabilizers found was compost.…”

Assessment of composted kitchen waste and poultry manure amendments on growth, yield and heavy metal uptake by Jute mallow Corchorus olitorius Linn.

“…This, in a way, can reduce the source of contaminant and subsequent transfer of heavy metal to edible portion of Corchorus. Previous studies have reported that the origin of a particular compost material could be a potential source of heavy metals in the plant tissues (Petersen et al 2003;Hanč et al 2008).…”

“…Composted organic manure especially from poultry wastes have been reported to improve mineral composition in tissues of vegetables such as Jute mallow (Mazen et al 2010;Jonathan et al 2012). In contrast to the beneficial roles of compost, it could also be a potential source of contaminants depending on its origin (Petersen et al 2003;Hanč et al 2008).…”

The influence of humic substance on Cd accumulation of phytostabilizer Athyrium wardii (Hook.) grown in Cd-contaminated soils

“…For the mobilization, metals are released into the soil and subsequently removed through native plant species. The application of poultry manure increased the available Cd concentration in soil and Cd uptake by Avena sativa L. proportionally during a 3-year experiment (Hanč et al 2008). According to Meeinkuirt et al (2013), the application of cow manure and organic fertilizer in the pot experiment and Osmocote® in the field experiment resulted in an increase of Pb uptake in both phytostabilization grass species of Thysanolaena maxima and Vetiveria zizanioides.…”
