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. | |
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. | |
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 | |
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. | |
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. | |
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. | |
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. | |
Cu Soil solution |
| The DGT allowed a representative estimation of the amount of Cu available in the soil. | |
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. | |
Phosphorus | Lycopersicon esculentum, Triticum aestivum | P deficiency assessed by yield response to P fertilizers; DGT provided excellent separation of responsive and nonresponsive soils. | |
