ABSTRACT Ingestion in food is a major pathway of cadmium (Cd) exposure for humans. It is therefore desirable to ensure that Cd concentrations in crops that enter the human food chain do not increase to levels that may lead to health risks. Phosphorus fertilizers contain Cd as a contaminant at levels varying from trace amounts to as much as 300 mg Cd kg–1 of dry product and therefore can be a major source of Cd input to agricultural systems. Fertilization can influence Cd accumulation in crops… Expand
Influence of Phosphate Fertilizer on Cadmium in Agricultural Soils and Crops(Symposium 3.5.1 Heavy Metal Contaminated Soils, International Symposium: Soil Degradation Control, Remediation, and Reclamation, Tokyo Metropolitan University Symposium Series No.2, 2010)
Phosphorus fertilizers contain cadmium (Cd) as a contaminant at levels varying from trace amounts to as much as 300 mg Cd kg−1 of dry product and therefore can be a major source of Cd input toExpand
Phytoaccumulation of Cadmium in Leafy Vegetables Grown in Contaminated Soil under Varying Rates of Compost and Phosphate Fertilizer Application
ABSTRACT Cadmium (Cd) contamination in agricultural soil is a global issue of concern because of its potential transfer to the human body through food chain interactions. Phosphate fertilizers usedExpand
Food Safety Issues for Mineral and Organic Fertilizers
Fertilizers and other soil amendments are required to maintain soil fertility, but some may be naturally rich in trace elements, or contaminated. As part of the overall consideration of usingExpand
An explanation of soil amendments to reduce cadmium phytoavailability and transfer to food chain.
TLDR
This review is aimed to provide a comprehensive note on Cd toxicity in humans and environment, its immobilization by different agents through variety of processes, and comparison of technologies for Cd removal from contaminated sites. Expand
Cadmium in potato and soybeans: Do phosphate fertilization and soil management systems play a role?
Abstract While it has been claimed that phosphate (P) fertilizers are essential for agriculture production, there is considerable debate regarding the safety of the cadmium (Cd) added to the soil inExpand
Strategies for reducing cadmium accumulation in rice grains
Abstract A high concentration of toxic heavy metal cadmium (Cd) in the paddy soils and its translocation and subsequent accumulation in the rice grain and the food chain is a global environmentalExpand
Effects of different potassium fertilizers on cadmium uptake by three crops
TLDR
Results suggest that when K fertilizers are applied to Cd-contaminated soils, both types and doses should be carefully considered to mitigate Cd accumulation in crops, especially the edible part. Expand
Long-Term Effect of Phosphate Fertilization on Cadmium Uptake by Oat and its Accumulation in Soil
Phosphate fertilizers contain varying amounts of cadmium (Cd) and other heavy metals as contaminants from phosphate rock (PR). Periodic applications of these fertilizers could result in measurableExpand
Cadmium and Phosphorous Fertilizers: The Issues and the Science
Abstract Non-nutritive metals, such as cadmium (Cd), occur naturally in all agricultural soils, in soil amendments (e.g. biosolids), and to varying degrees in phosphorous (P) fertilizers. ItsExpand

TLDR
The concern of long-term agriculture should be the depletion of available phosphate fertilizers, rather than the negligible contamination of the soil by trace metals from fertilizer inputs, the conclusion is confirmed by showing that the claimed correlations between fertilizer input and Cd accumulation in crops are not robust.

TLDR
The elevated pastoral soil Cd levels were not clearly reflected in grass or legume species but were displayed in weed species, and phosphatic fertiliser use is implicated in Cd accumulation in pastoral soils. Expand

TLDR
It was concluded that chlorocomplexation of Cd increased the phytoavailability of biosolid-borne Cd to a similar degree as soil (fertilizer) Cd. Expand
Management Factors which Influence Cadmium Concentrations in Crops
TLDR
It is necessary to develop management practices which can produce acceptable levels of Cd in food, both in the short and long term, while maintaining stable and affordable crop production. Expand
