If you're planning to attend the World Ag Exp in Tulare this week, be sure to stop by Seminar Trailer 2 between 1-3 PM on Tuesday and Wednesday to catch the UC Dairy Series.
Talks will include presentations on water and nutrient management for forage crops (full agenda here), including information about maximizing water productivity from winter cereals in the face of increasing drought and regulations on water use. This "Water-wise Dairying" session will take place...

We're off to a good start to the rainfall year! As farmers begin to turn attention to fall-planted small grains, be sure to check out UC's extension resources on the UC Small Grains Research and Information Center and the associated UC Small Grains Blog. Resources include the following:
UC Davis and UC Cooperative Extension are excited to share newly developed tools that optimize nitrogen (N) fertilizer management in wheat and other small grains. The new tools and case studies illustrating how they've been applied in commercial settings will be discussed at an upcoming webinar on 11/4/2021 from 2-4 PM (2 INMP/CURES CEU credits available for those who REGISTER).
These tools are the product of many years of UC research and include an interactive website that provides customized, site-specific nitrogen fertilizer recommendations. Recommendations are based on monitoring of crop health and...
Dry conditions this year have generated common questions from growers such as “when should I irrigate to maximize yield?” and “will I be able to take this crop to seed?” Many of the principles that dictate irrigation strategies in wheat are similar to those of other crops. Understanding wheat's growth stages can help growers develop a strategy for drought years.
Relative to many crops, small grains are considered plastic, or flexible, in their growth habit and yield potential. This means that the crop adjusts its growth to the scarcity or abundance of resources (water and nutrients) encountered during the season. The impacts of stress on crop yield are not...

Concerns about a growing resistance to herbicides
In Mediterranean or arid climates, particularly in areas with marginal soils, crop rotations are often limited to a narrow range of hay, pasture, a handful of winter legumes, or rainy-season grasses. Arid conditions and weathered soils drove Australia's rainfed grain growers to adopt no-till strategies earlier than their counterparts in California. While beneficial from a water use perspective, successful no-till systems depend on herbicides to control weeds that were traditionally kept in check with tillage.
Dependence on herbicides alone in these systems has resulted in weeds with resistance to multiple modes of action. In Australia, there is one...
