“…The decrease in quality parameters due to increased Cd level could partly be owing to its toxic effect and partly due to its ionic imbalance (Dahiya et al, 1987) [4] . These results were in conformity with these of Prince et al (2002) [17] .…”

In order to evaluate the effects of different combinations of cadmium and FYM on growth parameters, yields and quality parameters of semi rabi sorghum (var. Gundari), a pot experiment was conducted at Junagadh Agriculture University, Junagadh. The treatments comprising of different five levels of cadmium viz., 0, 10, 20, 40 and 80 mg kg -1 and three levels of farmyard manure viz., 0, 10 and 20 t ha -1 in Completely Randomization Design (Factorial) repeated thrice. The result revealed that higher value of growth, yield and quality parameters were achieved in treatment Cd0 (0 mg Cd kg -1 ) and decreased with increasing levels of Cd from 0 to 80 mg kg -1 . The highest values of growth, yield and quality parameters were achieve under the application of 20 t FYM ha -1 (F20). Among all treatment combinations, the highest values of plant height, number of leaves, stem diameter, dry leaves, dry stem, dry root yield, green forage yield and dry matter yield were observed with treatment combination F20Cd0. However, interaction effect of Cd and FYM was found non-significant with respect to quality parameters viz., crude protein, crude fiber and ash content of sorghum at harvest.

“…Of the potentially toxic metals, Cd is most dangerous because it presents no evidence of toxicity in plants even when they have accumulated excessive concentrations (Prince et al 2002). The solubility of Cd in soils is strongly influenced by pH, soil texture, and organic matter (McBride 1994;Agbenin 2006).…”

Increasing accumulation of cadmium (Cd) in urban and peri-urban savannah soils under long-term wastewater irrigation has been reported in some studies. Because of the insidiousness of Cd in soil ecosystems and the human health implications after the consumption of Cd in food and vegetables containing residues of the metal, we investigated its adsorption and solubility controls in selected urban soils. The latter were spiked with Cd at the rate of 200 mg Cd kg À1 soil and allowed to react at pH 4-8 for 25 days. Cadmium adsorption was stronger at higher pH, with a maximum at about pH 8, just below its first hydrolysis constant (pK 1 ¼ 10.1). Total Cd in the soil solution (Cd T ) was speciated into free Cd 2þ and Cd complexes. Free Cd 2þ accounted for between 66% and 88% of Cd T . The dominant Cd complexes were Cd-fulvate, CdCl þ and CdOH þ in two of the three experimental field soils, while Cd-fulvate and CdSO o 4 were the dominant ones in the third. Free Cd 2þ was undersaturated with regard to the Cd 3 (PO 4 ) 2 --Ca 3 (PO 4 ) 2 solubility isotherm in the soil solution at pH 7.0, while above pH 7.0 Cd 2þ in the solution was supersaturated with respect to Cd 3 (PO 4 ) 2 --Ca 3 (PO 4 ) 2 solubility, but undersaturated with respect to the octavite (CdCO 3 ) solubility isotherm. The slopes of the Àlog [Cd 2þ ] versus pH relations indicated that mechanisms other than the solid phase formation controlled Cd 2þ concentrations in the soils.

“…Atkinson et al, 2011;McGrath et al, 1988;McLaughlin et al, 1999;Santos et al, 2015). Transfer from soil to plants and so entry into food chains is a primary concern in relation to soil metal content and, while any metal can become toxic at elevated concentrations, cadmium (Cd) is a particular problem because it is a non-essential element that can accumulate in plants at levels that are harmful to humans and other animals before becoming phytotoxic (Prince et al, 2002). Rice is known to accumulate Cd when grown on contaminated soils and human health impacts, particularly kidney disease and associated conditions, have been conclusively linked to Cd exposure via rice consumption (Cai et al, 1990;Chaney, 2015;Swaddiwudhipong et al, 2012).…”

Cadmium (Cd) contaminated soils from the Mae Sot district in northwest Thailand, a region in which rice Cd concentrations often exceed health limits (0.4 mg/kg) set by the World Health Organisation, were examined for isotopically exchangeable Cd (Cd E values using a 111 Cd spike) to determine how this rates as a predictor of rice grain Cd in comparison with soil total Cd and solution extractable Cd (using the commonly applied BCR scheme and, in an attempt to distinguish carbonate bound forms, the Tessier soil sequential extraction scheme reagents). Step 1 of the BCR scheme (0.11 M CH3COOH) and step 1 of the Tessier scheme (1M MgCl2) showed the highest R 2 values in regressions with rice Cd (91% and 90%, respectively), but all predictors were strongly linked to rice Cd (p<0.001) and could be used for prediction purposes. One soil, of the six tested, was an exception to this, where all predictors overestimated grain Cd by a factor of 2.5 to 5.7, suggesting that rice grain Cd had been restricted here by the differing flooding regime and subsequent changes to redox conditions. E values and Tessier step 1 extractions were closely related, indicating that these measurements access similar pools of soil Cd. Separately, the isotopic exchangeability (representing bioavailability) of Cd was also assessed in two soils amended with rice husk and miscanthus biochars (0, 1, 5, 10, 15 and 20% w/w) in order to assess the utility of the biochars as a soil amendment for immobilising Cd in-situ. One soil showed significant reductions in Cd E value at 5% rice husk biochar addition and at 15% miscanthus biochar addition however, based on the E value-rice grain Cd regression relationship previously established, the E values in the amended soils still predicted for a rice Cd concentration above the health limit. In the second soil, neither of the biochars successfully reduced the Cd E value. This indicates that further work is needed to customise biochar properties to suit specific soil and contaminant situations if they are to be used successfully for remediation of metal contaminated soils.
