USDA-ARS Spence Research farm
1572 Old Stage Rd.
(36.628792, -121.540791)
Thursday October 18th, 9 am to 10:30 am
UC Cooperative Extension will host a field day at the USDA-ARS Spence research farm to show a field trial evaluating water use in drip irrigated celery. This is an opportunity to see first- hand the effect of water management on celery growth. We will discuss using weather data for scheduling irrigations using the CropManage online tool, water application monitoring using flowmeters, soil moisture monitoring using tensiometers, and the feasibility of improving irrigation scheduling using satellite-based tools. This is a joint project among UC Cooperative Extension, CSU Monterey Bay, NASA-Ames, and the USDA-ARS. The project is funded through the USDA-Specialty Crop Grant Program, administered through CDFA. Cooperators include Dole Fresh Vegetables, Inc., and Wilbur Ellis.
Location: The trial is located in a field adjacent to Spence Rd. Enter the ranch from the west side of Old Stage Rd. Turn right at the water reservoir and drive to the end of the road.

CropManage Hands-on Workshop:
Bringing Irrigation and Nutrient Management Decision Support to the Field
Date: Tuesday, April 24, 2018
8:00am – 12 pm
Location: Monterey County Agriculture Conference Room
1432 Abbott St. Salinas, CA 93901
- Learn how to use CropManage to support irrigation and nutrient management decisions and record-keeping
- Learn the new version of CropManage (3.0) – also available in Spanish
CropManage is a free online decision support tool for water and nutrient management of coastal crops. Based on in-depth research and field studies conducted by the University of California, CropManage provides real-time recommendations for efficient irrigation and fertilization applications— while maintaining or improving overall yield.
At this free workshop, we will provide hands-on training so that you can learn to use the newest version of CropManage (3.0) which has been updated to be more compatible for in-field use by farm staff. CropManage is now available in Spanish.
Crops currently supported by CropManage include strawberry, raspberry, head, romaine, and leaf lettuce, broccoli, cauliflower, cabbage, celery, bell peppers, spinach, baby lettuce, cilantro, and mizuna.
Who should participate? Vegetable and berry growers, ranch managers, other farm staff, and technical service providers are welcome. The workshop is for both new and current CropManage users.
What to bring? This is a participatory workshop. Please bring a tablet or laptop computer so that you can follow along and participate in the exercises. Each participant will need a user account for CropManage. Please set up a free user account at v3.cropmanage.ucanr.edu before the workshop.
RSVP by Friday, April 20, 2018 to Lennis Arriaga at larriaga@ucanr.edu or 831 759-7353.
