Title

Effects of urea formulation on sugarcane yield, nitrogen uptake and nitrous oxide emission in tropical Queensland.

Weijin Wang; B. Salter; Steven Reeves; et al. Griffith Research Online (Griffith University, Queensland, Australia) 2014

Other claims from this paper (13)

Intervention effect PCU released nitrogen into soil considerably more slowly.
Intervention effect PCU resulted in lower soil mineral nitrogen concentrations in the first 1–2 months than conventional urea.
Intervention effect PCU maintained higher soil mineral nitrogen levels in the mid to late cropping season than conventional urea.
Intervention effect NICU had lower soil nitrate contents than conventional urea in the initial three months.
Intervention effect Annual cumulative nitrous oxide emissions were 11.4–18.2 kg N/ha with no significant differences among urea forms or fertilizer rates.
Mechanism Similar emissions suggested soil nitrous oxide production was mainly driven by factors such as rainfall rather than soil mineral nitrogen.
Intervention effect Urea formulation did not affect sugarcane yield at the same nitrogen application rate.
Intervention effect Reducing nitrogen from 140 to 100 kg N/ha decreased sugarcane yield with conventional urea.
Intervention effect Reducing nitrogen from 140 to 100 kg N/ha decreased sugarcane yield with PCU.
Intervention effect Reducing nitrogen from 140 to 100 kg N/ha did not decrease sugarcane yield with NICU.
Intervention effect Crop nitrogen uptake decreased with decreasing application rate for conventional urea.
Intervention effect Crop nitrogen uptake did not decrease with decreasing application rate for NICU.
Recommendation Coated fertilizers may potentially allow lower nitrogen application rates without crop nitrogen deficiency.
