Optimizing cotton irrigation and nitrogen management using a soil water balance model and in-season nitrogen applications
Agricultural Water Management(2019)
摘要
•Irrigation application amounts were evaluated using soil water depletion estimates.•In-season nitrogen rates were split at first square and bloom.•Optimal irrigation was replacing 50% of the depleted soil water until first bloom.•Optimal split nitrogen treatments varied across research locations and years.•Site-specific tools estimating soil nitrogen loss in-season are needed.
