Hand-held electronic devices help you make better nitrogen fertilizer decisions

Figure 2

This is the third post in a blog series focused on improving nitrogen (N) use efficiency in California small grains. This post discusses two hand-held devices that indicate plant N levels in small grains to help optimize fertilizer decisions. The tools...

Implementing N-Rich Reference Zones to Inform In-Season N Fertilization Practices

Figure 1.

This is our second in a series of blog posts on improving nitrogen (N) use efficiency in California small grains. This post focuses on the use of N-rich reference zones to assess in-season N status and make management decisions based on crop need. Our...

New resources available for conducting and interpreting soil nitrate quick tests

Measuring soil nitrate in the field.

Measuring soil nitrogen (N) prior to fertilizing can improve N fertilizer management. The soil nitrate quick test is a simple and low-cost test. It provides a ballpark estimate of the soil nitrate-N concentration in the rootzone. Nitrate is a highly...

Adapting in-season N rates for wheat during a dry year

Figure 3. Wheat N uptake as a percentage of seasonal total expressed as a function of GDD.

After almost 6 weeks without a substantial rainstorm, there is finally some precipitation starting to appear in the 10-day forecast for the Sacramento Valley. The lack of rain thus far has made it difficult to proceed with N fertilizer topdress...

Start planning your nitrogen management strategy for fall-planted wheat now (and consider using a N-rich reference strip to manage your N more precisely)

In Season N Reference

Recent UCCE research has illustrated the value of in-season applications of nitrogen (N) fertilizer, particularly applications made at the early vegetative growth stages. This is typically the stage of growth when N demand from the crop is...
