Budgeting nitrogen for best results

摘要

Managing nitrogen this season has come into sharp focus in central-west NSW, after the region experienced record rainfall and significant flooding in 2010. Disease and water logging impacted on grain yields last year, particularly chickpeas. Heavy rainfall and flooding during the periods of grain harvest and early summer fallow also impacted on the amounts of crop biomass left in the soil as residues and on the fate of those residues.
