Nitrogen budgets are becoming more of a norm for California growers, and more than ever it's important for growers to get the greatest return for their nitrogen applications. One fertilizer management approach that can improve both yield and nitrogen use efficiency is to shift nitrogen applications from being mostly pre-plant to mostly in-season.
Research from the University of California has shown that in-season applications of nitrogen applied from the tillering to the jointing stage resulted in higher wheat yields and grain protein concentrations than pre-plant applications (Figure 1). This is something to keep in mind as we approach the winter growing season.
