e0“Urea was split applied to transplanted rice in a greenhouse experiment”
e5“For the first split application, fertilizer losses of 50% from urea were decreased to about 10% by use of NBPT and to 28% with PPDA alone, and by combination of PPDA with the algicide losses were 22%”

- Intervention effect Algicide addition extended the effectiveness of PPDA inhibition by about 2 days.
- Intervention effect Algicide addition with PPDA significantly increased rice plant N uptake and grain yield over urea alone.
- Intervention effect Al2(SO4)3 addition extended the effectiveness of PPDA by only about 1 day.
- Intervention effect Al2(SO4)3 addition slightly increased plant N uptake.
- Intervention effect Al2(SO4)3 addition failed to increase rice grain yield.
- Intervention effect NBPT effectively slowed urea hydrolysis.
- Intervention effect NBPT more than doubled rice plant N uptake over urea alone.
- Intervention effect NBPT increased rice grain yield by 38%.
- Intervention effect Percolation at 0.5 cm per day increased plant N uptake by about 6% in all treatments.
- Association Percolation was not essential for the beneficial effect of the urease inhibitors.
- Intervention effect NBPT decreased fertilizer N losses from urea in the first split application to about 10%.
- Intervention effect PPDA alone decreased fertilizer N losses from urea in the first split application to 28%.
