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.

Winter grains like wheat and triticale are incredibly attractive to nesting ducks. Winter grains are seeded in the fall and grow throughout the winter; by nesting season, a dense stand of winter grains near a planted rice field looks like a great nesting location with brood-rearing habitat just a waddle away. Several studies have found ducks may favor winter planted grains over natural uplands when they're available, and winter grains in rice country can produce far higher mallard nest densities and nest survival than anything in the Prairie Pothole Region.
Unfortunately, some winter grains like wheat have been declining along with its poor market price, and the Sacramento Valley's once robust mallard population is declining...

Summary Note
Mechanical cultivation is a useful tool in controlling herbicide-resistant Italian ryegrass individuals in a rainfed wheat system but is only about half as effective as Axial in reducing overall pressure from Italian ryegrass (expressed as a percentage of total groundcover). Growers should consider multiple approaches (chemical and mechanical) and integrate IPM strategies to reduce the spread of resistance among Italian ryegrass individuals.
Background
Italian ryegrass (Lolium multiflorum) has been shown to be a persistent weed for growers in rainfed winter grass...

UC Cooperative Extension will host the annual corn field meeting on Tuesday, October 15th, from 10:00-11:30am, on Tyler Island in Sacramento County. The agenda is pasted below and attached. In addition to providing information on the annual corn variety trial, this year's agenda includes presentations on nitrogen management for the upcoming small grains season. The attached version of the agenda includes a map and directions to the field site. We have applied for CCA continuing education credits, and light refreshments will be provided. RSVP is not required. Hope to see you in the field!
