Mn

Different Scandinavian agriculture soils

It is unlikely that the DGT techniques can be used to accurately predict the plant availability of Mn in crop production. DGT prediction of plant availability was best in anaerobic compared to aerobic soils. However, DGT can be a valuable tool in understanding factors affecting Mn availability.

Cd, Cu, Pb and Zn

Sorghum bicolour; Lactuca sativa

The DGT technique was fairly predictive of bioavailability in the greenhouse but not in the field.

(Agbenin and Welp, 2012)

Pb, Zn, Cu and Cd

Triticum aestivum

DGT and leachate concentrations in combination with bioassays in undisturbed soil cores can be used to account for metal bioavailability in soil.

(Mundus et al., 2012)

Cd, Zn

Taraxacum officinale and Plantago lanceolate

DGT did not perform better than soil solution, as Cd and Zn uptake in the plant was not limited by diffusion

(Muhammad et al., 2012)

Cd, Zn

Rice (Oryza sativa)

Due to the inherent heterogeneity of the rice rhizosphere soils, deployment of DGT in dried and homogenized soils offers the best possibility of a soil screening tool.

(Williams et al., 2012)

Cu, Zn and Cd

Various vegetables

DGT can be used for the general evaluation of the risks associated with soil contamination with Cu, Zn and Cd in field conditions.

(Senila et al., 2012)

Hg

Rice (Oryza sativa)

DGT can predict the bioavailability of methyl mercury in rice paddy soil, and the DGT method can provide a quantitative description of the rate of uptake of this bioavailable methyl mercury.

(Liu et al., 2012)

Zn and Cd

Salix smithiana clone

Single extraction with the DGT value of Cd was not able to predict shoot Cd removal on the tested soils.

(Puschenreiter et al., 2013)

Cu Soil solution

The DGT allowed a representative estimation of the amount of Cu available in the soil.

(Garrido and Mendoza, 2013)

Cu Fontinalis antipyretica

Tatiana Garrido and Jorge

The DGT approach was demonstrated to be a dynamic in-situ measuring technique that can be used as a surrogate of bio-indicators if the cationic correction is taken into account.

(Ferreira et al., 2013)

Phosphorus

Lycopersicon esculentum, Triticum aestivum

P deficiency assessed by yield response to P fertilizers; DGT provided excellent separation of responsive and nonresponsive soils.
