UC ANR publishes nitrogen management advice for fruit, nuts and other crops
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.
For more information on the nitrogen management training materials, visit http://ciwr.ucanr.edu/NitrogenManagement.
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.
Communication is key to action on California’s new water narrative
UC scientists, students and water agency professionals took a critical look inwards and a radical look outwards when they gathered in Sacramento in October to reimagine California water.
The event was the fourth annual gathering sponsored by UC ANR's California Institute for Water Resources and the University of California Water Security and Sustainability Research Initiative, UC Water.
While science is the hallmark of a research-oriented institution like UC, the participants were asked to recognize their important role not just as scientists but also communicators.
“We have a big role in educating the public,” said Roger Bales, engineering professor at UC Merced who has been active in water and climate research for more than 30 years. “Scientists are political actors. Facts do not speak for themselves.”
Felicia Marcus, chair of the California Water Resources Control Board and a conference panelist, asked the scientists to make their work accessible, and if they are uncomfortable with plain language, “write it both ways.”
“Complexity can lose people easily,” she said.
The conference keynote speaker, futurist Kim Stanley Robinson, also addressed the divide between scientific discourse and popular understanding, in particular when speaking about climate change.
“There is a strange disconnect between what the scientific community is telling the world and what the world is hearing. As a result of data analysis, science is announcing to the world there is climate change. Individuals cannot perceive climate change,” he said. “Show them in ways that can be understood by the senses. The story has to be told with pragmatism and common sense.”
The Reimagining California Water Conference pursued the water journey from the high-mountain headwaters of the Sierra Nevada to the vast groundwater basins in the valleys below. Over the last century, the mountains were blanketed with snow each winter, storing water that melted slowly in the spring and summer to provide a reliable source of water for farming and communities below. However, climate change is telling a new tale. Warmer weather means less snow and more rain will fall on the mountains during the winter. The quick runoff must be managed in a way that preserves it for use in the summer.
“We need groundwater recharge because we're losing the snow pack quicker than we thought we would,” Bales said.
The new California water narrative has prompted scientists and policy makers to take a serious look at the potential for “flood-managed aquifer recharge” or Flood-MAR. Flood-MAR is a management strategy that uses water from rain or snowmelt to flood agricultural lands and working landscapes, such as refuges, floodplains and flood bypasses.
Successful implementation of Flood-MAR requires the identification of land for groundwater recharge, understanding the economic and agronomic impact of using agricultural land for recharge, and impacts of high-volume recharge on groundwater quality. But the potential is enormous.
“The state's underground basins are capable of storing 500 million acre-feet of water,” said Graham Fogg, UC Davis professor of hydrogeology. “That's like 500 Folsom reservoirs.”
Though the enormity of rewriting the California water story might seem an insurmountable challenge, panelist Debbie Franco noted that the passage of Sustainable Groundwater Management in 2014 happened when the state's unsustainable reliance of groundwater spiked during the 2011-2016 drought, reducing municipal water quality, drying domestic wells and causing land to sink.
“What seems impossible, after four years of drought, can be possible,” Franco said. “What will be the next thing? Get a sense of the solutions now.”
New dust sources resulting from a shrinking Salton Sea have negative ecological and health impacts
Scientists at UC Riverside investigating the composition of particulate matter (PM) and its sources at the Salton Sea have found that this shrinking lake in Southern California is exposing large areas of dry lakebed, called playa, that are acting as new dust sources with the potential to impact human health.
“Playas have a high potential to act as dust sources because playa surfaces often lack vegetation,” said Roya Bahreini, an associate professor of environmental sciences, who led the research project. “Dust emissions from playas increase airborne PM mass, which has been linked to cardiovascular disease, respiratory disease, and mortality.”
Study results appeared recently in Environmental Science and Technology.
Bahreini's team set out to test whether emissions from playas change the composition of PM10 (particulate matter with diameters up to 10 microns) near the Salton Sea. The team assessed the composition of playa soils (recently submerged underneath the Salton Sea), desert soils (located farther from the sea), and PM10 collected during August 2015 and February 2016.
They found that dust sources contributed to about 45 percent of PM10 at the Salton Sea during the sampling period while playa emissions contributed to about 10 percent. Further, they found that playa emissions significantly increased the sodium content of PM10.
Her team also found that playa soils and PM10 are significantly enriched in selenium relative to desert soils.
Bahreini explained that selenium can be a driver of aquatic and avian toxicity. “Additionally, higher selenium enrichments in PM10 during summertime suggest that selenium volatilization from the playa may become an important factor controlling the selenium budget in the area as more playa gets exposed,” she said.
Alexander L. Frie, a graduate student in environmental sciences and the first author of the research paper, urges that the Salton Sea be paid close attention since, although it is widely considered a large ecological disaster, with no serious monitoring and remediation efforts the sea may also create a human health crisis for the surrounding area.
Samantha C. Ying, an assistant professor of environmental sciences and a coauthor on the paper, stresses that monitoring the increase in dust sources over time is necessary to quantify its contribution to local health problems.
“Our study shows that the shrinking Salton Sea is contributing to dust sources in the region,” she said. “Even considering just the small area of playa that is exposed now, the contributions are significant.”
Another concern the researchers point out is that water that is currently diverted from the Colorado River and directed into the Salton Sea is scheduled to end before 2018. The resultant decrease of inflow into the sea will likely cause a decline in water level, exposing more playa, and therefore emitting more dust.
“With more playa being exposed, we expect total PM10 concentrations to increase and human exposure to these particles in downwind areas will also increase,” Bahreini said. “Therefore implementing any project, for example, creating shallow water pools over the playa, that limits formation of salt crusts on the playa will be valuable.”
Bahreini, Frie and Ying were joined in the study by Justin H. Dingle, a graduate student in Bahreini's lab.
The study was funded by UCR Regents' Faculty Development Award, USDA National Institute of Food and Agriculture, a UCR Provost Research Fellowship, the U.S. Geological Survey and ANR's California Institute for Water Resources.
