Other claims from this paper (13)
- Observation Most of the total soil Cu, 51.12%, was in the residual fraction.
- Observation Exchangeable fraction (EX-) of soil Cu averaged 2.71%.
- Observation Carbonate bound (CARB-) fraction of soil Cu averaged 0.74%.
- Observation Organically associated (OM-) fraction of soil Cu averaged 2.74%.
- Observation Mn oxide bound (MnOX-) fraction of soil Cu averaged 0.21%.
- Observation Amorphous Fe oxide bound (AFeOX-) fraction of soil Cu averaged 13.35%.
- Observation Crystalline Fe oxide bound (CFeOX-) fraction of soil Cu averaged 29.11%.
- Association Exchangeable and carbonate bound Cu fractions contribute most to Cu availability to oat.
- Association Cu concentration and uptake in oat were positively correlated with DTPA-extractable Cu, MnOX-Cu and AFeOX-Cu.
- Association Cu concentration and uptake in oat were positively correlated with total Cu.
- Association Cu fractions in MnOX, AFeOX, CFeOX, RES and total Cu varied directly with DTPA-extractable Cu and clay content.
- Method / resource Plant Cu concentration and uptake can be predicted by an equation including DTPA-extractable Cu and clay content.
- Method / resource DTPA-extractable Cu is a good predictor of Cu availability in Haryana soils.
