  journal={Plant and Soil},
A long-term greenhouse column experiment using two soils of different textures amended with dewatered, composted and alkaline-stabilized sludges (biosolids) tested the effect of aging on trace metal solubility, mobility and crop uptake over 15 cropping cycles. Specifically, soil chemical properties and extractability of Cu, Zn and Mo were measured after each cropping cycle, and soybeans (Glycine max (L.) Merr.) grown as the final crop were analyzed for those metal concentrations in the seeds… Expand

Phytotoxic effects of Cu and Zn on soybeans grown in field-aged soils: their additive and interactive actions.
The critical roles of the properties of the soil, the nature of the metal, and the level of other toxic metals present on the development of differential phytotoxicity due to soil Cu and Zn are demonstrated. Expand
Metal Availability following Paper Mill and Alkaline Residuals Application to Field Crops.
Results of this study indicate that paper mill biosolids and alkaline residuals, when applied with respect to regulations and soil pH, have a limited effect on metal accumulation in plants and soil. Expand
Residual effects of papermill biosolids and forest-derived alkaline materials on crop yield and plant metal accumulation
Abstract: Combined papermill biosolids (PB) and forest-derived alkaline by-products are known for their direct benefits to agricultural crops, but their residual effects after several years ofExpand
Effect of soil metal contamination on glyphosate mineralization: role of zinc in the mineralization rates of two copper-spiked mineral soils.
Interestingly, Zn appeared to alleviate high-Cu inhibition of mineralization in the Arkport soil, suggesting that increased mineralization rates in high Cu soil with Zn additions might have been due to alleviation of cellular toxicity by Zn rather than a mineralization specific mechanism. Expand
Effect of composted sewage sludge with organic garbage on planting watercress in red soil
The results showed that the addition of compost could significantly promote the dry weight yield of watercress and the contents of TOC and TN in the soil increased dramatically after 60 days of planting but the content of TP decreased. Expand
Direct, Residual, and Cumulative Effects of Mixed Sludge Generated by Coca-cola Soft-Drink Industry on Crop Yield, Soil Fertility, and Heavy-Metal Uptake in Rice–Wheat Cropping Sequence
A field experiment was conducted to evaluate the effects of directly, residually, and cumulatively applied mixed sludge generated by the soft-drink industry on rice and wheat yields, soil fertility,Expand
Application of sewage sludge improves growth, photosynthesis and antioxidant activities of nodulated alfalfa plants under drought conditions
Evidence is provided for a beneficial effect of sewage sludge application for nodulated alfalfa plants subjected to cyclic drought, which might have contributed to protect nodules from oxidative stress as indicated by low products of lipid peroxidation. Expand
Distribution of Cd, Ni, Cr, and Pb in Amended Soils from Alicante Province (SE, Spain)
Heavy metals can be transferred from soils to other ecosystem parts and affect ecosystems and human health through the food chain. Today the use of biosolids to improve the nutrient contents of aExpand
Mineralogy and Distribution of Cd, Ni, Cr, and Pb in Biosolids-Amended Soils From Castellón Province (NE, Spain)
Heavy metals can be transferred from soils to other portions of the ecosystem, with effects at both the ecosystem level and on human health from transmission through the web chain. For several years,Expand
Relationship between photosynthetic capacity, nitrogen assimilation and nodule metabolism in alfalfa (Medicago sativa) grown with sewage sludge.
Sewage sludge did no affect nodulation but decreased nodule enzyme activities involved in carbon and N metabolisms that may lead to accumulation of toxic N-compounds in alfalfa. Expand


Long-term changes in the extractability and bioavailability of zinc and cadmium after sludge application
Changes in the extractability and uptake by crops of sludge metals in a long-term field experiment, started in 1942, were measured to assess whether Zn and Cd are either fixed by the sludge/soilExpand
Bioavailability and crop uptake of trace elements in soil columns amended with sewage sludge products
In order to assess the potential impact of long-term sewage sludge application on soil health, the equivalent of about 25 years of agronomic applications of low-metal (`EQ') sewage sludge productsExpand
Effect of sludge-processing mode, soil texture and soil pH on metal mobility in undisturbed soil columns under accelerated loading.
Leachate and soil pH were substantially depressed in dewatered and pelletized sludge soil columns and increased for alkaline-stabilized and ash treatments, especially at low pH. Expand

The long-term potential for sewage sludge amendments to alter forage trace metal concentrations was determined on bromegrass, which received no sludge application for 20 yr following annualExpand
Effects of potentially toxic metals in soil derived from past applications of sewage sludge on nitrogen fixation by trifolium repens L

Molybdenum uptake by forage crops grown on sewage sludge-amended soils in the field and greenhouse.
Molybdenum (Mo) is a plant-available element in soils that can adversely affect the health of farm animals. There is a need for more information on its uptake into forage crops from waste materials,Expand
With the availability of sensitive multielement analytical capability, it is no longer essential to use chemically aggressive soil tests to extract measurable levels of most trace elements. However,Expand
The phytoavailability of cadmium to lettuce in long-term biosolids-amended soils
A field study was conducted to assess the phytoavailability of Cd in long-term biosolids-amended plots managed at high and low pH. The experiment, established 13 to 15 yr prior to the presentExpand
Metal mobility at an old, heavily loaded sludge application site.
Despite heavy loadings, fine soil texture, and evidence of past and ongoing metals leaching, examination of the bulk subsoil indicated no statistically significant increases in metals concentrations when comparing pooled sludge plot soil profiles with controls, which may not be reliable evidence for immobility of sludge-applied metals.

Effect of microbial activity on trace element release from sewage sludge.
The results suggest that microbial acidification via S oxidation can mobilize trace elements from sludge, and that Elemental mobility in field situations would also be governed by other factors, including the capacity of soil to buffer acidification and to adsorb mobilized elements. Expand
