New ‘big data’ tools help California wheat farmers reduce fertilizer guesswork
Growers in California grapple with plenty of climate uncertainty – but a new set of tools can help wheat farmers make crucial fertilizer decisions with more precision and confidence.
An interactive website integrates these tools – developed or adapted by researchers at the University of California, Davis and University of California Cooperative Extension – that provide farmers with recommendations for applying nitrogen fertilizers, specific to their own sites and conditions.
While factoring in those weather variables, the management tool also draws data from two indicators of nitrogen sufficiency or deficiency: the results of a soil nitrate quick test (a simple test previously used in vegetable crop systems along the coast), and comparisons of plant health in the broader field to that in a “nitrogen-rich reference zone” (a practice originally developed in the Midwest).
Using them in tandem, in the context of California wheat growing, is a novel approach. In a Nov. 4 webinar, Lundy will introduce the use of the nitrogen-rich reference zone, a small area in a field where extra fertilizer is added at the beginning of the season.
“This project is a unique example of digital agriculture at work in an applied setting,” he explained. “We are integrating ‘big data' sources like site-specific soil and weather data, as well as satellite, drone and other sensor measurements into an interactive web interface. This allows users to receive straightforward yet highly customized recommendations from somewhat complex agronomic models.”
The team conducted 11 on-farm demonstrations in fields representing a wide range of agroecosystems, including the Sacramento Valley, San Joaquin Valley, Delta region, and Tulelake Basin.
Fritz Durst, a western Yolo County-based grower who participated in one of the case studies, said that the process of gathering the data was “actually pretty simple” and the tool “eliminates much of the guesswork” for managing nitrogen fertilizers.
“This tool is extremely helpful for me to make decisions about the most efficient and cost-effective method for applying nitrogen to my wheat,” Durst said.
In addition to potentially increasing crop productivity and farmer net-income, the tool can benefit the environment by reducing the amount of nitrate leaching from fertilizer applications, according to Lundy.
“It's not only trying to say how much fertilizer to put down, sometimes it's trying to confirm you don't really need any fertilizer,” he said.
More resources and events related to the Nitrogen Fertilizer Management Tool for California Wheat – including demonstration activities – will appear on the UC Small Grains blog.

Black Lives Matter, Pride Month, budget and Big Dig Day
It's hard to believe it is already Friday; this week has certainly been chaotic. While dealing with the challenges of a pandemic that may be entering a second wave soon, we've all had to process a great deal of emotion over the death of George Floyd and anger over the ongoing injustice against the Black community. As I said earlier this week, our mission to serve California can never fully come to fruition if Black Americans and other historically victimized groups continue to suffer hatred and bias. Easy enough to say, but what does that mean going forward?
This week, the most important action was to quickly make it clear where we stood on the situation and offer emotional support to our colleagues and communities of color. Let me be clear: Black Lives Matter. It's hard to know if our messages were the best they could be, but they were offered with sincerity and the hope of stimulating productive discussions. Those discussions are critical to next steps; we have to think and learn and then identify where and how we can enhance our programs and policies to build that healthy, peaceful and prosperous California for all.
I'm not sure what those next steps will encompass, but I am sure that, working together, we can design actions that will help us achieve that goal. As we work toward that, I ask all of you to be open to new ideas and have patience with each other. We are all flawed human beings that are doing the best we can while dealing with a pandemic, an uncertain economy, sheltering-in-place and all the other upheaval that has been thrown at everyone this past few months.
One action that I would like to offer right now is to read this very thoughtful article and one of the best explanations of "white privilege" I've seen. These easy-to-understand, everyday examples are shared with compassion despite the hurt they caused; every white person needs to read this. If your reaction to that is to say, "I don't need to read this because I'm not a racist," then you are probably one of the people that need to read it the most.
In June, every Wednesday at 6 p.m., you are invited to join UC ANR colleagues to view films about LGBTQ+ communities and participate in discussions after the shows from the comfort of wherever you are sheltering in place. The length of each session will vary with the length of the film. Register for the ANR Pride Film Fest at http://ucanr.edu/pride2020 to get the Zoom link.
Before I close, I'm sure many of you have been following our budget situation and actions taken by the state legislature. At this time, we don't know for sure how large of a cut we may be facing, but are preparing for various scenarios. We'll share more detail on that next week. I can commit to you that any actions taken on the budget will prioritize our people. You – our academics, programmatic staff and the support staff that enable them all to be successful – are our most important infrastructure. Without you, the mission cannot be delivered!
In closing, the last action I'll suggest for this week is for you to please take care of yourself. Sleep in this weekend, get out into the sun, spend some quality time (Zoom or in person) with family and friends. Take part (safely) in a protest of some sort or find another way to support our Black community.
Best wishes and warm regards to all,
Glenda
