Abstract A greenhouse experiment was aimed at assessing the effects of poultry manure, sorghum, and clover residues (0 and 15 g kg− 1) on the zinc (Zn) bioavailable fraction in contaminated calcareous soil using two chemical assay, including diffusion gradient in thin films (DGT) and diethylene triamine pentaacetic acid-triethanolamine (DTPA-TEA), and a bioassay with corn (Zea mase L.). The results showed that poultry manure, clover, and sorghum residues application increased dissolved organic carbon (DOC) by 53.6 and 36.1, and 9.2%, respectively, with respect to unamended soils, as well as decreasing soil pH by 0.42, 0.26, and 0.06 units, respectively. These changes did result in increases of Zn effective concentration (CE) and DTPA-Zn, and plant Zn concentration as a result of the increased exchangeable form of Zn. In the sorghum residues-amended soils, a reverse trend was observed for CE-Zn compared to the DTPA method. Correlation analyses revealed that unlike CE-Zn, DTPA-Zn had a significant positive correlation with organic fractions that can be considered as an equivalent to the fact that the DTPA method had been overestimated Zn available to the plant. The best correlations between corn metal concentrations and soil metal bioavailability were obtained for CE-Zn using DGT technique, which also provided the best Zn bioavailability estimate. It is concluded that sorghum residues could be used to reduce the phytotoxicity risk of Zn in calcareous contaminated soil, and DTPA method is the less robust indicator of Zn bioavailability than DGT technique.

In order to study the soil amend agent how to suppress the function of the vegetables absorb Pb, the Pb was added in the experimental soil in pakchoi pot, The lime and peanut dry cake were added to the experimental soil as modifier, and the varying concentrate of modifiers, lead effect on pakchoi biomass and lead accumulate were discussed in this paper. Through the determination of Pb content of aboveground and underground part of pakchoi by ICP, the lime and peanut dry cake can resist lead absorption were proved, and the lime achieved better inhibitory effect of the two. By analyzed the BCF of two parts of pakchoi, two types of modifiers had proved can reduce the pakchoi BCF of Pb in the soil. The lime was more efficient than the peanut dry cake on reducing BCF of Pb.

This study was conducted to determine the effects of organic materials to remediate contaminated soil with heavy metals. A pot study was performed by growing maize (Zea mays) in metal contaminated soil (10 kg pot-1) and soils amendments with cow manure dust, poultry manure dust, vermicompost dust, fern dust, water hyacinth dust, mustard stover dust and barnyard grass dust each at 5 g kg-1 soil. The results showed that Pb, Cd, Ni, Cr and Co uptake by maize depended on the organic materials type. Water hyacinth dust, fern dust, mustard stover dust, and barnyard grass dust addition led to decreased metal content in maize, and this decrease was better expressed with 20.5 to 33.3% for fern dust, 17.3 to 22.0 % for water hyacinth, 18.6 to 21.3% for mustard stover dust, 17.33 to 20.5% for barnyard grass dust. Cow manure dust, poultry manure dust and vermicompost dust led to increased metal content in the maize, and this increase was 6.80 to 18.7 % for cow manure, 18.9 to 86.7 % for poultry manure and 17.4 to 16.0 % for vermicompost. The different effectiveness of organic amendment on metal uptake by maize plant could be due to the nature of organic matter where water hyacinth dust, fern dust, mustard stover dust, and barnyard grass dust were mainly originated from plant. On the other hand, cow manure, poultry manure and vermicompost were mainly the excreta collected from cattle, poultry and earthworms. However, immobilization and phytoextraction techniques might be used to remediate soils which are contaminated with heavy metal.Bangladesh J. Agril. Res. 42(4): 589-598, December 2017
