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 goal is to help growers and consultants learn how to use N-rich zones to improve small grain N fertilizer use efficiency and reduce negative environmental outcomes. To demonstrate what we know about this practice across the small grain growing regions of the state, our team has helped growers establish N-rich zones in their fields across a wide range of soil and climatic conditions. These demonstration sites are in the Sacramento Valley, Delta Region, San Joaquin Valley, and the...

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 been hard at work developing extension resources that we can share digitally. Please take a moment to visit our 2020 Virtual Small Grains Field Day:

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 plant-available form of nitrogen. Using the soil nitrate quick test when N fertilizer decisions are being made will help define a range of fertilizer rates appropriate for that field. This can provide several benefits. These include improved N use efficiency, lower input costs, improved grain yield or grain protein, and reduced N loss to the air or below the crop rootzone.
