Other claims from this paper (10)
- Intervention effect Flooded soil doubled dry matter production and P uptake of immature rice compared with moist soil.
- Intervention effect Zn concentration in rice tissue decreased at the high P rate on moist soil but not on flooded soil.
- Intervention effect Percentage recovery of fertilizer Zn by rice was greater from flooded than moist soil, especially at the high P rate.
- Intervention effect Mixed and surface Zn applications were comparable in flooded rice.
- Intervention effect Middepth Zn placement was less effective than mixed and surface applications in flooded rice.
- Intervention effect Surface and middepth Zn placements were less effective than mixing in nonflooded soil.
- Intervention effect Mobility of Zn applied as ZnSO4 was comparable in flooded and moist soil in laboratory studies.
- Intervention effect DTPA-extractable Zn tended to be higher in moist than in flooded soil.
- Recommendation DTPA may not be a reliable measure of Zn availability in flooded soils for rice.
- Mechanism Differences in Zn uptake by rice may be related to root distribution or other root characteristics.
