Title

Effects of reducing and postponing nitrogen application on soil N supply,plant N uptake and utilization of summer maize

Jiyun Jin Plant Nutrition and Fertilizing Science 2010

Other claims from this paper (8)

Intervention effect Reduced and postponed N application increased maize N accumulation rate over farmers practice.
Intervention effect Reduced and postponed N application did not decrease N use efficiency.
Intervention effect Reduced and postponed N application did not decrease dry biomass accumulation.
Intervention effect Reduced and postponed N application did not decrease N accumulation amount.
Intervention effect The treatment improved synchronization of soil N supply and maize demand.
Intervention effect The treatment decreased nitrate N accumulation in the 0-100 cm soil profile.
Intervention effect The treatment reduced apparent field N loss at maturity.
Recommendation Reduced and postponed N application is recommended as feasible and could save 30% N fertilizer versus farmers practice.
