N management case studies: Utilizing N-rich reference zones in California small grain crops

As the fall planting season begins, we'd like to share recently developed case studies detailing N management actions and crop productivity outcomes in several small grain fields during the 2019-20 growing season. Growers from different parts of the...

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

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

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...

2020 Virtual Small Grains Field Day

Due to the health concerns surrounding COVID-19, we had to cancel our annual field day that typically occurs in May at UC Davis. While there is no full replacement for seeing field trials in person, the UC small grains research and extension team has...

New resources available for conducting and interpreting soil nitrate quick tests

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...
