[Form tendency and bio-availability dynamics of Cu and Zn in different farm soils after application of organic fertilizer of livestock and poultry manures].
Huan Jing Ke Xue. 2015 Jan; 36(1):314-24.HJ

Abstract

Soil incubation experiments were conducted with different sources of manures containing heavy metals to evaluate the bioavailability of heavy metals (Cu and Zn) and their form transformation in different soils. This study may assist in developing strategies to ascertain the loads of heavy metals which entered into soils together with manures, and promote policies to evaluate the ecological risk in agriculture soils. The results showed that, during the six months of soil incubation, the pH value of acidic soil increased and the pH value of calcareous soil reduced. After adding chicken manures, the contents of available Cu in both calcareous and acid soils were significant lower than those in the equivalent inorganic salt treatments, but there was no significant difference between the treatments in the contents of available Zn in both calcareous and acid soils. Furthermore, there were also no significant differences between pig matures and the equivalent inorganic salt treatments in the contents of available Cu and Zn in both calcareous and acid soils. The results of form tendency showed that the main forms of Cu and Zn in both calcareous and acid soils, which entered into soils together with manures, were exchangeable, carbonate, Fe-Mn oxides, and organic. And the proportions of different heavy metals species in calcareous and acid soils were different with different manures sources. After six months of incubation, the contents of exchangeable and Fe-Mn oxides Cu, Zn were lower than those in the equivalent inorganic salt treatments, the contents of organics Cu and Zn were higher than those in the equivalent inorganic salt treatments, and other Cu and Zn forms in soils showed no difference with inorganic salt treatments.
