The Future of Groundwater Management

Most experts agree that using satellites to monitor groundwater is the future for California agriculture. Satellite measurements are accurate enough to determine water usage of a given crop, which has led Groundwater Sustainability Agencies (GSAs) to look at this as a way to monitor groundwater. Satellite monitoring of crop water use for groundwater management is the wave of the future, according to Joel Kimmelshue, Ph.D., principal agricultural scientist for Land IQ, and it is a method that the regulatory agencies are using. Tracking of evapotranspiration (ET) through infrared technology for mapping has been around for quite some time, but satellites...

Prevent Water Stress in the Central Valley and Set Trees Up for Bearing Next Year’s Crop

This year, long-range weather forecasts from the National Weather Service call for above-normal temperatures for the southern half of the state and cooler temperatures to the north. As for rainfall, much of the Central Valley looks to have less than a 50% chance of precipitation in November. If this dry forecast proves to be correct, what steps can growers and farm managers take to prevent water stress and set their trees up for bearing next year’s crop? Keep Up with ET “They have to continue to stay in farming mode, keep up with irrigation to meet evapotranspiration demands,” said UCCE...

A Pound of Brrrrr: Late-Season Irrigation Can Help Prevent Freeze Damage to Walnut Trees

Walnut growers, particularly those in the northern Sacramento and San Joaquin valleys, used to view sudden fall freezes as a one-in-seven- or one-in-10-year occurrence. But consecutive freezes during the past three autumns may cause them to change their thinking and become more prepared for cold snaps before leaf drop. “This is something that’s going to have to be on [walnut growers’] radar,” said Luke Milliron, a University of California Cooperative Extension orchard systems advisor for Butte, Glenn and Tehama counties. “My perception is walnut growers see these freeze events in fall as less predictable, and they creep up on them...

Almond Irrigation Systems of the Future

Implementation of new irrigation system technologies and strategies is continuously on tree nut growers’ minds. Irrigation systems of the future will need to be nimble and flexible to deal with variability in the orchard for maximum water use efficiency. Growers may look at water use as it relates to rate and timing, but there is another important aspect to consider when designing an irrigation system in an orchard, known as spatiotemporal variability. Spatiotemporal variability may be caused by variation in soil physical and hydraulic properties, which affects soil water infiltration rates. Soils that have high spatiotemporal variability are said to...

Pest, Nutrition and Irrigation Considerations in a Lean Year

Low almond prices may encourage almond growers to reduce or alter management inputs for pests, nutrition and irrigation in their orchards. But experts say growers need to consider when it is safe for the crop and the tree to cut costs and resources without damaging the tree or future yields, and decisions should be made on an orchard-by-orchard, case-by-case basis. Nutrition Management The decision to cut back on nutrient inputs will depend on the orchard. More often than pest management, there will be instances where cutting an input will not be feasible. One question to ask is: What nutrients...
