e0“The deep placement of urea fertilizer (DMU) containing 1% (W/W) of the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) on soybean growth and seed yield was as effective as those of the coated urea (CU) and lime nitrogen (LN) in a field research.”

Other claims from this paper (15)
- Intervention effect DMU was as effective as lime nitrogen for soybean growth and seed yield.
- Observation Average seed yield under LN was 464 g·m −2.
- Observation Average seed yield under DMU was 461 g·m −2.
- Observation Average seed yield under CU was 405 g·m −2.
- Observation Average seed yield under U was 396 g·m −2.
- Observation Average seed yield under control was 373 g·m −2.
- Intervention effect CU deep placement increased shoot dry matter accumulation relative to U and control.
- Intervention effect LN deep placement increased shoot dry matter accumulation relative to U and control.
- Intervention effect DMU deep placement increased shoot dry matter accumulation relative to U and control.
- Intervention effect Deep placement of CU, LN and DMU increased soybean shoot nitrogen accumulation over U and control.
- Intervention effect DMU, CU and LN had higher daily nitrogen fixation activity than control.
- Intervention effect DMU, CU and LN had higher daily nitrogen absorption rate than control.
- Intervention effect DMU inhibited soil nitrification similarly to LN for eight weeks.
- Intervention effect Increasing DMPP concentration did not markedly increase nitrification inhibition.
- Recommendation The authors concluded that 1% DMPP urea is efficient for deep placement in soybean cultivation because it costs less than CU and LN.
