Catching up with the Cloud: WiFi-based Irrigation Controllers

By Morgan Hopkins, FYN Agent UF/IFAS Miami-Dade County

Who would have thought that many of life's activities can now be accomplished with an app? From dating, to grocery shopping, and now irrigation scheduling - our hand-held computers (a.k.a. smart phones) have simplified so many of our tasks!

UF-ABE's Dr. Kati Migliaccio knows a thing or two about irrigation apps
Catching On
Within the last year or so, we (the Florida Yards andNeighborhood Program’s Urban Conservation Unit) have seen more and more customers from our Landscape Irrigation Evaluation and Rebate Program (LIERP) show an interest in WiFi or cloud-based irrigation controllers – attracted by the appeal of convenience and high-tech features.

If we see it in the field, we need to know how to use it! So thanks to some generous brand reps, we’re now using and learning more about how these new cloud-based, smart irrigation controllers work. Once connected to a local WiFi signal, these controllers generate run times based on external information, such as area weather data. The WiFi capability allows homeowners and property managers to access their systems from an internet connection anywhere in the world. Each brand offers several different interactive features, and most simplify the timer programming process through user-friendly app design.

Irrigate From Anywhere
As technology continues to advance, we will see these controllers change internally as well as externally - as in our perception of water management in the landscape. Here’s to hopping on the smart app band wagon and hoping that positive water conservation behavior change comes along with it!

Dispatches from the Virgin Islands: Anticipation

This week Agronomy Masters Student David Hensley is embarking on a research trip to the University of the Virgin Islands (UVI) in St. Croix. Mr. Hensley will be stationed there until late spring and has agreed to send dispatches to IrriGator about his work and progress there. Here is the first in his series of contributions:


Currently I'm working on an MS thesis degree in the agronomy department with an Agroecology concentration. I just submitted my thesis proposal and now know that my research is focused on the interaction between synthetic nitrogen fertilization and biological nitrogen fixation in crop rotations. My overall interests are nitrogen fixation, crop rotation, intercropping, and nutrient cycles.

Next Stop: St. Croix
My advisor, Dr. Diane Rowland, teaches a class called Global Agroecosystems that I enrolled in for my first semester, fall 2016. One of the great things about this course is the large diversity of guest lecturers we had, and it was one of those lecturers that introduced me to the opportunity at UVI. Dr. Stuart Weiss is an agronomist there and gave us a guest lecture about his research into low-input agriculture in tropical systems, which involves a lot of crop rotation, intercropping, and the like, often incorporating nitrogen fixing crops. I came to UF with an existing history and interest in tropical regions, studying agricultural policy in West Africa in my undergraduate degree and doing a couple of basic on-farm volunteer experiences for a few months in Senegal and Jamaica. All of this combined to pique my interest in his work immediately.

I'll be in St. Croix from mid-January to the end of April. Thankfully, their growing season is year-round, so I'll be exposed to plenty of activity during that time.

Looking Ahead 
Obviously it's hard not to get excited about traveling to a new place, especially one as beautiful as St. Croix. After Dr. Weiss' lecture, I googled some images of the island, and I couldn't believe how amazing it looked. I love being in the Caribbean, as I'm sure most anyone would, and I love tropical farms, too, so I am really excited about being back in the mix, with some formal agronomy experience this time, to see how it all works and get involved with it.

At work on a nutrient study in Live Oak, FL: Sienna Turner, Maria Zamora and David Hensley
At a basic level, getting some formal experience with tropical agriculture is enough for me. But I'm sure I'll meet that goal no matter what else happens. A more ambitious goal that I have is to walk away knowing a little more about what works in practice in low-input tropical systems as far as crop rotation and intercropping goes, and my ideal goal is to get a lot of information about the realities of nutrient cycling and nitrogen fixation in that kind of system. I'm hoping for the best!


Editor's Note: Originally intended as a series of reports spanning the duration of Mr. Hensley's research assignment at UVI, this content will continue on a more Agronomy-focused digital platform. Read the next and final dispatch here.

Research and science policy share the stage at the 2016 AGU Fall Meeting

As it has for decades, the Fall Meeting of the American Geophysical Union (AGU) took place this month in San Francisco, CA. AGU is a professional society representing earth and space scientists, who study a broad variety of sub-disciplines such as Hydrology, Biogeosciences, Atmospheric Sciences, Seismology, Oceanography, Geophysics, and more. Although each of these specialties sound fairly niche on their own, together they compose a huge community of scientists. The AGU Fall Meeting attendance in 2015 amounted to 24,000 people, making this conference the largest annual gathering of geoscientists in the world. Every day while walking up the stairs of the conference center, I remarked to myself that the geoscientists on each floor looked like ants flooding out of a mound.


The AGU Fall Meeting includes hundreds of oral and poster presentations. World-class scientists from all over the globe attend this meeting to present recent scientific findings and meet with old and new colleagues. As a result, the networking opportunities at the AGU Fall Meeting are unmatched, and students have easy access to renowned researchers throughout its duration.


With 2016 being an election year, this year’s Fall Meeting included several notable talks related to science policy and politics. California Governor Jerry Brown spoke to the crowd on topics related to science funding for the geosciences, as well as “green” policies that California state legislators have spearheaded.


Sally Jewell, the U.S. Secretary of the Interior, was another notable speaker at this year’s meeting. Secretary Jewell spoke of the importance of ensuring that science has a seat at the table, because “if you are not at the table, you are on the menu.” She also emphasized the need for scientists to fight disinformation with relatable facts, which requires effective communication of science’s real-world impacts. In addition to speaking, Secretary Jewell attended the conference, and even stopped by the poster session. The networking doesn’t get much better than this, folks!



In addition, Dr. Waleed Abdalati, former NASA Chief Scientist (2011-2012), gave an enlightening talk on the history of earth observations from space. He highlighted several old NASA promotional materials and news snippets from decades past that emphasized how much we’ve learned about the earth in a short time period. For example, it wasn’t until 1969 when satellites captured imagery of Hurricane Camille that we understood the scale, magnitude, and organization of hurricanes. That’s only 37 years ago! Dr. Abdalati ended his presentation by sharing some of his wisdom on the topic of science communication, particularly on potentially divisive issues:



As you may have noted, talk of science policy and politics always veers towards the topic of science communication. AGU’s operations include staff devoted to science policy. This group of public affairs specialists and analysts hosted several events at this year’s Fall Meeting, which speaks to how expectations for scientists to communicate effectively are increasing. At some of these events, you could find science communication cards that highlighted how commonly-used words in science can come across as confusing and misleading to laypersons:


Effective science communication was also in focus at the poster sessions. Thousands of students present posters, and about 5,000 choose to compete for the Outstanding Student Paper Award (OSPA). Of these 5,000, the top 3-5% presenters in each sub-discipline of AGU will be awarded with an OSPA. Scientists attending the conference are asked to judge the posters. The judges never reveal to presenting students that they are judges, which requires all presenters to give their best throughout their allotted time in in the poster session – I thought this was a great idea! I presented two posters this year: one in an educational session, and one in a session on hydrology:


The Fall Meeting is always in San Francisco, but, due to renovations taking place at the conference center in which the meeting is hosted, next year’s conference is coming to New Orleans, LA! For those of us in Florida, that makes for a much shorter journey, which is a great opportunity. Don’t pass it up!

On the Cutting Edge of Water Saving Science: A Look Back at 2016

By Michael Gutierrez

We're not usually in the habit of ending the year having to clarify what it is we do and why, but here we are. From my perspective, 2016 was a remarkable year in water research. Summer water quality issues in South Florida put our water in the national headlines for weeks (the debate rolls on). Then projections about future water demand in Florida underscored the need for continued work around water-use efficiency. Meanwhile our group of UF/IFAS water specialists on campus and around the state remained focused on providing solutions for present and future challenges, and I kept doing my best to find unique ways to communicate those efforts to you. What follows are some highlights from 2016.

Water researchers: Maria Zamora, Mackenzie Boyer, Eliza Breder, Michael Dukes & Bernard Cardenas
Statewide Work
One of the measures of successful research is how well it can move from design and data to real-world impact. For the Dukes research group (pictured above), the smart irrigation study in Orange County continued to inform policy this year when the Board of County Commissioners formally recognized the water-saving capacity of smart technology. There is already work around creating a watering restriction variance for smart device users

This year also saw UF/IFAS go even bigger on promoting and coordinating water-focused work in Florida by creating 5 positions for regional specialized agents in water. Each agent concentrates on the water issues specific to their sector. This year we profiled Dr. Lisa Krimsky from the South District. We’ll continue to profile the other water RSAs in 2017 to learn about the water issues of note in their sectors. In the meantime, keep up with their efforts on Twitter.

Irrigation Tools and How to Get Them
In my experience as a water resources tech with UF/IFAS I have never seen more interest in basic landscape irrigation know-how among IFAS staff around the state than in 2016. I wrote about one instance of assisting an agent in Lake County earlier this year. But we had other requests for help that we were not able to address. Fortunately, some of the best irrigation-focused programs in the state are currently lending their expertise to fashioning workshops where extension agents can learn irrigation system audit basics. How do I know they’re the best? Well in 2016 I had the privilege to work with both of them.  

Miami-Dade’s Urban Conservation Unit administers an irrigation rebate program as large as its region requires. This program is a model of UF/IFAS and utility collaboration. Further, despite their whopping load of field work they remain largely accessible online and eager to share their knowledge. 
On the Southwest coast of Florida is Manatee County Extension. Their mobile irrigation lab also executes an irrigation rebate program, the details of which I was so impressed with that I requested a ride-along this summer while in the area on other field work. The result of that meeting was a short video that tries to do some justice to how effective that team is in educating the public about water-use efficiency.
As more utilities move toward incentivizing smart irrigation technology, the demand for trainings and workshops for area irrigation contractors continues to grow. That’s where we come in. In 2016 the Dukes research group conducted 3 trainings in Southwest/Central Florida on proper installation and use of soil moisture sensors and weather-based irrigation controllers. Look for us in your area in 2017.

Dr. Kati Migliaccio at ASABE AIM 2016
Home Team
This year ASABE held their annual international meetings (AIM) in Orlando. Most of our water group presented research there and I had the opportunity to document really exciting student competitions like robotics and the fountain wars. AIM also served as an occasion for recognizing noteworthy work as Dr. Michael Dukes was honored with the John Deere Gold Medal and Dr. Kati Migliaccio won for Outstanding Associate Editor (pictured above). 

This was not the only honor Dr. Migliaccio would receive in 2016. This year the UF Water Institute recognized Dr. Migliaccio as a Faculty Fellow. Watch her Distinguished Scholar Seminar on the future of water management here.

For me collaborating with students is one of the more rewarding aspects of work in academia. At ASABE, UF ABE robotics team leader (and the future of precision ag) Amanda DeCanio was integral to me being able to complete the short video I was tasked with. Later, Ms. DeCanio agreed to reflect on her ASABE AIM experience for IrriGator.
UF ABE PhD Candidate and NSF Graduate Research Fellow Natalie Nelson continued contributing excellent entries to IrriGator this year – taking our readership along on her treks to conferences and researcher gatherings across the country. And while I missed my first Irrigation Show and Education Conference since 2012 this year, Food and Resource Economics PhD Candidate Maria Vrachioli attended as an E3 Learner and chronicled her experience with the wider irrigation industry for us as well.  

2017: You Are Invited!

The fall of 2016 found us dedicating considerable lab time to pressure regulating sprinkler bodies. This work helped inform what will eventually result in EPA WaterSense certification of spray sprinkler bodies (SSB) as water-saving devices. Despite the solitary nature of this lab work – research associate Bernard Cardenas toiling at the testing apparatus for hours with different sprinkler brands - we found inventive ways to bring our audience/the greater public into the lab with us. Similarly this summer, Dr. Michael Dukes and I translated a sensor wiring mishap and some great corrective work in Pasco County into an elucidating dialogue about water saving technology and perception. Look for this piece to go national in 2017’s first issue of Irrigation Today. 

We’re going to stay on the cutting edge of irrigation research because that’s where we need to be. See you in the new year!

Mehrhof Gardens: Florida-Friendly Landscaping in Our Own Back Yard

This summer I was involved in documenting the planning and execution of UF’s newest Florida-Friendly Landscaping demonstration piece: Mehrhof Gardens. Named after the buildings in its vicinity, Mehrhof Gardens helps beautify a highly visible, well-trafficked area of campus while serving as a living example of sustainable landscaping practices.

How Sustainable is Sustainable?
But can you really maintain an aesthetically pleasing landscape sustainably? This is a pressing question of late. This year the 1000 Friends of Florida, UF GeoPlan Center and FDACS released the Florida 2070 report. Its projections of future population growth, land-use alterations and greater demand on resources paint a sobering picture about what’s ahead for the Sunshine State. In light of this information, some in the know are reacting with austere prescriptions, while others are confident that we have solutions for tomorrow’s challenges.


In the meantime, when you're in the neighborhood stop by Mehrhof Gardens and maybe you’ll be inspired to add a Florida-Friendly touch to your home landscape.

Irrigation Show & Education Conference 2016: A Student’s Perspective

Last week, UF Graduate Student Maria Vrachioli attended the Irrigation Association’s Irrigation Show and Education Conference as a participant in the immersive E3 Program for students and instructors. This is Ms. Vrachioli’s report back.


I am a third year PhD student in the Food and Resource Economics (FRE) Department in the University of Florida.  As an economist, I have focused on creating applied mathematical models to analyze water efficiency and productivity in the agricultural sector, where the ever increasing demand for food is challenging us to develop more efficient and sustainable ways of exploiting our natural resources. 
Maria Vrachioli - PhD Candidate, UF

Given that agriculture is the biggest consumer of fresh water in the world, irrigation is at the epicenter of this dilemma. To this end, my doctoral dissertation will be focused on understanding how the adoption of new irrigation technologies by farmers can allow them to use a scarce water resource more efficiently, while maximizing their profits. With the support of colleagues at the World Bank, this analysis will be applied on a data base of water consumption and agricultural production in Morocco.

E3 Program Ready
Attending the 2016 Irrigation Show and Education Conference as an E3 Learner will be a good way for me to bridge my academic research on agricultural water use with the latest technologies and practices in irrigation. I took two courses during the event: 
  • Agricultural Irrigation Specialist
  • Principles of Irrigation: Agriculture

Classroom POV: Irrigation is part theory and practice
Reflection
These courses gave me a really good base on which I can build my future research and let me understand deeply the terminology used by the experts in the irrigation field. I would say that I enjoyed both of the courses, but the Principles of Irrigation in Agriculture course was a little bit more interesting for me as through this 2-day course I was afforded a good review of all the information I learned in different irrigation classes at university.

In the General Session presentation
One of the things that I found really surprising was despite the fact that we have so many efficient irrigation technologies available for farmers, sometimes training is lacking for them to properly adopt new irrigation technology. This results in less efficient irrigation practices and less profits for the farmers.

I spent many hours in the show floor of the IA event and I was really surprised by all the new and innovative technologies presented there. You could find all kinds of companies related to agriculture and landscape irrigation.

Hear the Bringing Water to Life Podcast live from the expo floor
Advice for 2017
Attending the Irrigation Show was an amazing experience for me and I strongly recommend students to attend it in the future. I strongly believe that applying to E3 cannot only help you build on your theoretical and practical skills through the courses, but also it is the best way to expand your network and why not get in contact with your future employer in the irrigation industry.

See you in Orlando, FL!!!

“It’s really about communicating”: An Interview with Dr. Eric McLamore

This November, Dr. Eric McLamore, associate professor in Agricultural and Biological Engineering, was honored with a USDA Excellence in Teaching award in the New Teacher category. Dr. McLamore is popular among students in the ABE department for his wide-ranging research and a grant writing course he teaches which includes learning about and creating digital media. In fact, not too long ago Dr. McLamore worked with IrriGator on a short video about air conditioning condensate irrigation.

In this same collaborative spirit, Dr. McLamore recently shared with us some thoughts on his current research and receiving a teaching award.

USDA Excellence in Teaching award recipients for UF/IFAS: Eric McLamore and Nicole Stedman 
What do you focus on in your research?

We make biosensors – measurement technology for measuring small molecules, viruses, cells and everything in between. Most of our work is applied within food safety or water quality; although we do some medical and nutritional work as well.

Right now we have a big project where we’re trying to measure a bacterium in food called Listeria monocytogenes – it’s a particularly dangerous organism that affects children and the elderly. It’s a major problem across the world. We’re working in the US with food producers on both the water quality side – things like irrigation water within the farm and also the processing facility. And we’re also working overseas. We have a project in Colombia working with displaced refugees monitoring that pathogen as well as others on food - trying to help people who are very vulnerable from a health standpoint. We also have some work initiating in that same sort of humanitarian context in Malaysia right now.
La Toma: Colombian community impacted by small-scale gold mining
I mentioned that we measure small molecules. One of the larger things we’re measuring in a similar humanitarian effort in Colombia is mercury. That project is focusing on illegal gold mining which is prevalent in that region of the world. We’re working with a community of displaced Afro-Colombians and indigenous tribes who live in the mountains. The illegal miners use mercury to create what’s called amalgamate - which is how they extract the gold. The miners don’t understand the damage that they’re doing to the environment and to themselves and the indigenous communities by using so much mercury. We’re finding levels hundreds of times higher than what the World Health Organization allows in any drinking water. We also measure fish that the locals consume. We’re trying to put together a project where we can assist the community as well as help train the miners who are exposed to the most dangerous levels of mercury.
Read a WHO report on gold and mining health
You teach a grant writing course which emphasizes the usefulness of digital media in terms of professional development. How do you use these tools in your research?  

This is enormously important. In engineering we do a lot of nanomaterials and chemistry and physics and all these things – the fundamental sciences drive what we do. But at the end of the day it’s really about communicating it to people and making sure that they know where we’re coming from, they understand how to use the science in the way that we intended it to be used. 

Sampling and testing for mercury in water
And that really comes down to oral communication, digital media - these sorts of things. From a technology standpoint as well, the sensors typically output data that goes to a smart phone. So we’re getting to a point now where we’re going to start creating apps. We’re going to develop some of those things for the communities so that it’s user-friendly and not so sciencey.


Right now on the mercury project we’re working with a filmmaker in Colombia. We have several videos online. We need to get the message out and give a voice to the people who need help.

What does it mean to be honored with the new teacher award at this stage of your career?

It was primarily associated with the humanitarian work and bringing that kind of research into the classroom. It’s humbling and it’s a big honor. Just standing in the room with some amazing people who have been teaching their entire career and learning from them about all the things they do gave me a lot of confidence in what I’m doing.

Researchers and community leaders meeting 
What are some projects you’re focusing on in 2017?

The big thing is these two humanitarian projects. There are a lot of other projects that we’re working on that are important. For example, I have a student who is trying to make a type of breathalyzer, but it monitors a compound associated with diabetes that is the number one diagnostic tool for preventing death in children – it’s called diabetic ketoacidosis. He’s monitoring a specific maker in the breath that’s kind of difficult to measure with ornery kids who are sick and can’t communicate as adults can. Hopefully we can make a cute, fun breathalyzer that monitors this marker and helps these kids stay out of the emergency room because it’s a deadly problem. We have some other very important projects, but the humanitarian work has been a focus of the last year and will probably continue to be for the next four or five years.
