DTPA has the ability to increase uptake by plants of several metals. In the present study DTPA increased uptake from Hacienda and Yolo loam soils of Pb210 and Am241. There was a decreased effect in the 2nd and 3rd harvests relative to the first. It had no effect on uptake of Sb125 or Hg203. EDDHA increased uptake of Sb125 from Yolo loam, and of Am241 from both soils. The effect of EDDHA did not persist in the soil as much as did that of DTPA. DTPA increased slightly the uptake of Cs137.
