UCCE researchers are currently working on a project to determine the value of sorghum silage in California dairy systems. Sorghum has gained attention in recent years as it is well adapted to drought/water stress conditions, but very little research has been done with respect to growing and feeding sorghum silage on commercial California dairies.
Please join us for a discussion on growing sorghum for silage. First year information from the project will be presented, as well as some other considerations for growing sorghum in California. Whether you're new to sorghum, or looking to refine management, these meetings will present the current knowledge of sorghum silage in California; California derived information...
Yellow plants equals nitrogen deficits—right? Maybe not!
When we have a very wet winter or spring, alfalfa fields may look yellow with diseased-looking leaves and delayed growth.
As farmers know, yellowing of leaves is a strong indication that nitrogen (N) may be limiting in the crop. Certainly that's true with corn, tomato, or wheat. It may also be the case in alfalfa too – but since alfalfa is a legume, it gets most of its N from biological nitrogen fixation (N2 fixation from bacteria which colonizes the roots, forming nodules), not from the soil. This ability enables alfalfa to grow well even on sandy N-depleted soils. N fertilizers are generally not recommended...

We are in the midst of a new and changing era of Worker Protection Standards (WPS). The U.S. Environmental Protection Agency (EPA) and the California Department of Pesticide Regulation (DPR) recently published the revised WPS, which is meant to increase protections for agricultural fieldworkers and pesticide handlers from pesticide exposure when they're working in farms, forests, nurseries and greenhouses. The changes are already affecting California agriculture!
What major regulatory changes have already gone into effect?
Several changes are required to have been in place as of January 2, 2017. These include:
- All 417,000 fieldworkers in California must attend annual pesticide safety...
When are seasonal heavy rains welcomed but worrisome? When rains fill reservoirs, but also turn fields into seas of standing water!
Such has been the case in northern California which has seen torrential rains in recent weeks. After 5 years of intensive drought, the 2016-2017 rains are a welcome relief, but pose a danger to many crops including alfalfa.
It seems strange that we're discussing water damage a few months after discussing (lack of) water stress!
Ah, the ups and downs of agriculture!
