California growers can download a new series of publications summarizing efficient nitrogen management practices from UC Agriculture and Natural Resources. The publications are designed to assist growers in complying with state regulations for tracking and reporting nitrogen fertilizer applied to crops, in an effort to prevent nitrogen from leaching into groundwater.
The science-based publications are associated with a series of trainings for growers and Certified Crop Advisers to develop efficient nitrogen management practices, an effort coordinated by UC ANR's California Institute for Water Resources.
“Our role is to provide farmers, agricultural consultants and policymakers the best science possible for making decisions on managing and protecting California groundwater,” said Doug Parker, director of the water institute.
The free publications, created from training materials, lessons learned from the training sessions and from additional UC research, can be downloaded at http://ucanr.edu/nmgmtpublications.
The following publications are now available for download:
· Principles of Nitrogen Cycling and Management
· Irrigation and Nitrogen Management
· Nitrogen Management for Nut Crops
· Nitrogen Management for Deciduous Fruit and Grapes
· Nitrogen Management for Citrus and Avocado
· Nitrogen Management for Cool-Season Vegetables
· Nitrogen Management for Strawberry Production
· Nitrogen Management for Processing Tomato
· Nitrogen Management for Corn on California Dairies
The publications were authored by Parker of California Institute for Water Resources; Patrick Brown, professor in the UC Davis Department of Plant Sciences; Allan Fulton, UC Cooperative Extension advisor, Tehama County; Tim Hartz, UC Cooperative Extension specialist emeritus, UC Davis Department of Plant Sciences; Dan Munk, UC Cooperative Extension advisor, Fresno County; Daniel Geisseler, UC Cooperative Extension specialist, UC Davis Department of Land, Air & Water Resources; Michael Cahn, UC Cooperative Extension advisor, Monterey, Santa Cruz and San Benito counties; Richard Smith, UC Cooperative Extension advisor, Monterey, Santa Cruz and San Benito counties; Marsha Campbell, UC Cooperative Extension advisor emeritus, Stanislaus County; Sat Darshan Khalsa, UC Davis project scientist; and Saiful Muhammad, UC Davis graduate student.
Developed in 2014, the training program has been offered at 11 different locations around the state, most recently in Fresno. More than 1,000 Certified Crop Advisers have taken the training.
The nitrogen management training curriculum was developed by a group of UC ANR faculty, specialists and advisors. The first day focuses on the nitrogen cycle in crop production systems, nitrogen sources, irrigation and nitrogen management, and nitrogen budgeting. The second morning covers annual and permanent crops and nitrogen planning practices.

The Nitrogen Management Training and Certification Program is a joint effort between the California Department of Food and Agriculture, UC Agriculture and Natural Resources, California Association of Pest Control Advisers' Certified Crop Adviser Program and the Regional Water Boards.

To mark its centennial anniversary, UCCE is hosting a Day of Science and Service to engage all Californians in creating an extensive statewide dataset on pollinators, food and water. Farmers may attend any of the myriad public celebrations on May 8. Computers will be available at the events for participation in the citizen science project. Or, if their schedules do not permit, they can quickly link in on their own computers or smart phones to record their efforts.
To participate, farmers can open http://beascientist.ucanr.edu. Click on the icon for water and find the farm on the map or search by address. The survey is set up for all California residents to record their water-saving in the household, garden and landscape. Farmers can click on the boxes that reflect their agriculture operations' water-saving strategies:
o Using drip/micro irrigation
o Scheduling irrigation efficiently
o Changing to drought-tolerant crops
o Using deficit irrigation
o Managing the soil
The system also allows users to upload a related photo. The whole process takes about a minute. No registration is necessary and the system doesn't collect email addresses. Twitter users can tweet about their participation in the Day of Science and Service using the hashtag #beascientist.
In addition to providing a better understanding of ongoing water-saving efforts, the Day of Science and Service aims to raise awareness about water conservation on farms and in households. Given the size of California, small savings across the board add up to a significant amount of water.
“Right now California is experiencing one of the worst droughts on record,” said Darren Haver, UCCE advisor in Orange County. “Some communities may run out of water in the next 10 years. If everyone in the state saves at least 10 gallons a month, we will be able to save over four and a half billion gallons a year.”
